2015-02-27 | Performance of Frozen Density Embedding for Modeling Hole Transfer Reactions | We have carried out a thorough benchmark of the FDE-ET method for calculating
hole transfer couplings. We have considered 10 exchange-correlation
functionals, 3 non-additive kinetic energy functionals and 3 basis sets.
Overall, we conclude that with a 7% mean relative unsigned error, the PBE
functional coupled with the... | 1502.07957v1 |
2015-03-17 | Coupled wire construction of chiral spin liquids | We develop a coupled wire construction of chiral spin liquids. The starting
point are individual wires of electrons in the Mott regime that are subject to
a Zeeman field and Rashba spin-orbit coupling. Suitable spin-flip couplings
between the wires yield an Abelian chiral spin liquid state which supports
spinon excitat... | 1503.05051v2 |
2015-03-18 | Oscillations and synchronization in a system of three reactively coupled oscillators | We consider a system of three interacting van der Pol oscillators with
reactive coupling. Phase equations are derived, using proper order of expansion
over the coupling parameter. The dynamics of the system is studied by means of
the bifurcation analysis and with the method of Lyapunov exponent charts.
Essential and ph... | 1503.05313v3 |
2015-03-27 | On Coupling NEC-Violating Matter to Gravity | We show that effective theories of matter that classically violate the null
energy condition cannot be minimally coupled to Einstein gravity without being
inconsistent with both string theory and black hole thermodynamics. We argue
however that they could still be either non-minimally coupled or coupled to
higher-curva... | 1503.07950v1 |
2015-04-16 | Coupling ferroelectricity with spin-valley physics in oxide-based heterostructure | The coupling of spin and valley physics is nowadays regarded as a promising
route toward next-generation spintronic and valleytronic devices. In the aim of
engineering functional properties for valleytronic applications, we focus on
the ferroelectric heterostructure BiAlO3/BiIrO3, where the complex interplay
among trig... | 1504.04091v1 |
2015-05-04 | From the Higgs to the top: Couplings and Rare Decays | Within the Standard Model the Higgs couplings to fermions and gauge bosons,
as function of the particle mass, are predicted to lay on a single line.
However, new patterns appear in multi-Higgs models that employ the
Froggart-Nielsen mechanism, where the diagonal couplings could lay on different
lines and flavor-violati... | 1505.00757v1 |
2015-06-03 | Non-canonical inflation coupled to matter | We compute corrections to the inflationary potential due to conformally
coupled non-relativistic matter. We find that under certain conditions of the
matter coupling, inflation may be interrupted abruptly. We display this in the
superconformal Starobinsky model, where matter is conformally coupled to the
Einstein frame... | 1506.01244v2 |
2015-06-14 | Targeting engineering synchronization in chaotic systems | A method of targeting engineering synchronization states in two identical and
mismatch chaotic systems is explained in details. The method is proposed using
linear feedback controller coupling for engineering synchronization such as
mixed synchronization, linear and nonlinear generalized synchronization and
targeting f... | 1506.04351v1 |
2015-06-16 | Higgs-inflaton coupling from reheating and the metastable Universe | Current Higgs boson and top quark data favor metastability of our vacuum
which raises questions as to why the Universe has chosen an energetically
disfavored state and remained there during inflation. In this Letter, we point
out that these problems can be solved by a Higgs-inflaton coupling which
appears in realistic ... | 1506.05106v2 |
2015-06-16 | Switchable Coupling of Vibrations to Two-Electron Carbon-Nanotube Quantum Dot States | We report transport measurements on a quantum dot in a partly suspended
carbon nanotube. Electrostatic tuning allows us to modify and even switch 'on'
and 'off' the coupling to the quantized stretching vibration across several
charge states. The magnetic-field dependence indicates that only the
two-electron spin-triple... | 1506.05137v1 |
2015-06-19 | Chimeras in networks with purely local coupling | Chimera states in spatially extended networks of oscillators have some
oscillators synchronised while the remainder are asynchronous. These states
have primarily been studied in networks with nonlocal coupling, and more
recently in networks with global coupling. Here we present three networks with
only local coupling (... | 1506.05871v1 |
2015-06-29 | Monte Carlo determination of the critical coupling in $φ^4_2$ theory | We use lattice formulation of $\phi^4$ theory in order to investigate
non--perturbative features of its continuum limit in two dimensions. In
particular, by means of Monte Carlo calculations, we obtain the critical
coupling constant $g/\mu^2$ in the continuum, where $g$ is the {\em
unrenormalised} coupling. Our final r... | 1506.08587v2 |
2015-09-05 | Boundary and coupled boundary-finite element methods for transient wave-structure interaction | We propose time-domain boundary integral and coupled boundary integral and
variational formulations for acoustic scattering by linearly elastic obstacles.
Well posedness along with stability and error bounds with explicit time
dependence are established. Full discretization is achieved coupling boundary

2015-09-08 | Probing Scalar Coupling Differences via Long-Lived Singlet States | We probe small scalar coupling differences via the coherent interactions
between two nuclear spin singlet states in organic molecules. We show that the
spin-lock induced crossing (SLIC) technique enables the coherent transfer of
singlet order between one spin pair and another. The transfer is mediated by
the difference... | 1509.02240v1 |
2015-09-17 | Polariton resonances for ultra-strong coupling cavity optomechanics in GaAs/AlAs multiple quantum wells | Polariton-mediated light-sound interaction is investigated through resonant
Brillouin experiments in GaAs/AlAs multiple-quantum wells. Photoelastic
coupling enhancement at exciton-polariton resonance reaches 105 at 30 K as
compared to a typical bulk solid room temperature transparency value. When
applied to GaAs based ... | 1509.05152v1 |
2015-10-12 | $β$-function formalism for inflationary models with a non minimal coupling with gravity | We discuss the introduction of a non minimal coupling between the inflaton
and gravity in terms of the recently proposed $\beta$-function formalism for
inflation\cite{Binetruy:2014zya}. Via a field redefinition we reduce to the
case of minimally coupled theories. The universal attractor at strong coupling
has a simple ... | 1510.03691v2 |
2015-10-14 | Pseudo-locality for a coupled Ricci flow | Let $(M,g,\phi)$ be a solution to the Ricci flow coupled with the heat
equation for a scalar field $\phi$. We show that a complete,
$\kappa$-noncollapsed solution $(M,g,\phi)$ to this coupled Ricci flow with a
Type I singularity at time $T<\infty$ will converge to a non-trivial Ricci
soliton after parabolic rescaling, ... | 1510.04332v3 |
2015-10-16 | Tachyon field non-minimally coupled to massive neutrino matter | In this paper, we consider rolling tachyon, with steep run-away type of
potentials non-minimally coupled to massive neutrino matter. The coupling
dynamically builds up at late times as neutrino matter turns non-relativistic.
In case of scaling and string inspired potentials, we have shown that
non-minimal coupling lead... | 1510.04795v2 |
2015-10-27 | Direct measurement of second-order coupling in a waveguide lattice | We measure the next-nearest-neighbour coupling in an array of coupled optical
waveguides directly via an integrated eigenmode interferometer. In contrast to
light propagation experiments, the technique is insensitive to
nearest-neighbour dynamics. Our results show that second-order coupling in a
linear configuration ca... | 1510.07900v2 |
2015-11-05 | Bounds on Neutrino-Scalar Yukawa Coupling | General neutrino-scalar couplings appear in many extensions of Standard
Model. We can probe these neutrino-scalar couplings by leptonic decay of mesons
and from heavy neutrino search. Our analysis improves the present limits to
$|g_e|^2<1.9\times 10^{-6}$ and $|g_\mu|^2<1.9\times 10^{-7}$ at 90\% C.L. for
massless scal... | 1511.01811v2 |
2016-01-22 | FG- coupled fixed point theorems for various contractions in partially ordered metric spaces | In this paper we introduce FG- coupled fixed point, which is a generalization
of coupled fixed point for nonlinear mappings in partially ordered complete
metric spaces. We discuss existence and uniqueness theorems of FG- coupled
fixed points for different contractive mappings. Our theorems generalizes the
results of Gn... | 1602.00543v1 |
2016-02-05 | Yukawa couplings in 6D gauge-Higgs unification on $T^2/Z_N$ with magnetic fluxes | We discuss the Yukawa couplings in 6D gauge-Higgs unification models on
$T^2/Z_N$ in the presence of magnetic fluxes. We provide general formulae for
them, and numerically evaluate their magnitude in a specific model on
$T^2/Z_3$. Thanks to the nontrivial profiles of the zero-mode wave functions,
the top quark Yukawa c... | 1602.01994v2 |
2016-02-08 | Leptogenesis in supersymmetry with one $L$ violating coupling | We have shown a new scenario of successful leptogenesis with one $L$
violating coupling and a relative Majorana phase playing the role of $CP$
violation. This is in contrast to the usual consideration of Feynman diagram
with at least two $L$ violating couplings. We have considered $R$-parity
violating Minimal Supersymm... | 1602.02684v4 |
2016-01-25 | Method for generating two coupled Gaussian stochastic processes | Most processes in nature are coupled; however, extensive null models for
generating such processes still lacks. We present a new method to generate two
coupled Gaussian stochastic processes with arbitrary correlation functions.
This method is developed by modifying the Fourier filtering method. The
robustness of this m... | 1602.04697v1 |
2016-02-26 | Coupled networks and networks with bimodal frequency distributions are equivalent | Populations of oscillators can display a variety of synchronization patterns
depending on the oscillators' intrinsic coupling and the coupling between them.
We consider two coupled, symmetric (sub)populations with unimodal frequency
distributions and show that the resulting synchronization patterns may resemble
those o... | 1602.08368v2 |
2016-04-04 | Coupling single emitters to quantum plasmonic circuits | In recent years the controlled coupling of single photon emitters to
propagating surface plasmons has been intensely studied, which is fueled by the
prospect of a giant photonic non-linearity on a nano-scaled platform. In this
article we will review the recent progress on coupling single emitters to
nano-wires towards ... | 1604.00846v1 |
2016-04-06 | Periodically modulated electromagnetically induced transparency | Phenomena of electromagnetically induced transparency (PEIT) may be
interpreted by the Autler-Townes Splitting (ATS), where the coupled states are
split by the coupling laser field, or by the quantum destructive interference
(QDI), where the atomic phases caused by the coupling laser and the probe laser
field cancel. W... | 1604.01539v1 |
