2024-02-19 | On Coupling Constraints in Linear Bilevel Optimization | It is well-known that coupling constraints in linear bilevel optimization can

2000-05-31 | Can Nucleon Tell Where the Couplings Run? | The comparison of magnetic moments of neutron and proton reveals three
possible states of a nucleon with the same correction of 0.033 for the central

2010-07-29 | Dilaton coupling revisited | We reinvestigate the dilaton coupling in the string theory, which comes from
a wrapped membrane. The ghost number anomaly associated with the string

are calculated for t... | 9811126v1 |
2004-02-11 | Linearly Coupled Directed Percolation in the Strong Coupling Regime | We consider directed percolation processes for particle types A and B coupled
unidirectionally by a transmutation reaction A -> B. It is shown that the

study the pur... | 0408005v1 |
2006-03-24 | Torsion, Dilaton and Gauge Couplings | Non-Abelian gauge fields are traditionally not coupled to torsion due to
violation of gauge invariance. However, it is possible to couple torsion to
Yang-Mills fields while maintaining gauge invariance provided one accepts that

2000-03-01 | Measurability of the non-minimal coupling | The "measurability" of the non-minimal coupling is discussed in the context
of the effective field theory of gravity. Although there is no obvious motive

correction. | 0003008v1 |
2005-09-20 | Shy couplings | A pair of Markov processes is called a Markov coupling if both processes have
the same transition probabilities and the pair is also a Markov process. We say

2007-10-26 | Unitarity constraints on MSSM trilinear couplings | For MSSM phenomenology, soft SUSY breaking dimension-three operators are
important, in particular the couplings between Higgs bosons and squarks. In
scattering processes, perturbative unitarity is violated at modest
center-of-mass energy if these couplings are much larger than the masses of the
scalar particles involve... | 0710.5175v1 |

2009-02-28 | Quantum Measurements of Coupled Two-Level Systems | We propose an approach to measuring nonresonant coupled systems, which gives
a parametrically smaller error than the conventional fast projective

are coupled. Such an interaction is shown to take a form of angular momentum
coupling governed by the field angular momentum inside the dielectric. As a
specific examp... | 1203.1121v1 |

representation the central oscillator couples with its position to an
oscillator bath. In the second one it couples with its momentum to the bath.
Both representations are related by a unitary transformation. If the central
oscillator couples wit... | 1203.6804v1 |

consisting of a GaAs double quantum dot and a coplanar waveguide resonator.
Derived values of the qubit-resonator coupling strength and the decoherence
rate indicate strong coupling, which assures distinct vacuum Rabi oscillation
in the system. The a... | 1206.0674v1 |

the individual Higgs couplings. The new data allow us to specifically test the
effective coupling to photons. We find no significant deviation from the
Standard Model in any of the Higgs couplings. | 1207.6108v2 |
2012-09-28 | Spin-Hamilton Operator, Graviton-Photon Coupling and an Eigenvalue Problem | We solve exactly the eigenvalue problem for a spin Hamilton operator
describing graviton-photon coupling. Entanglement of the eigenstates are also
studied. Other spin-coupled Hamilton operators involving spin-1 and spin-2 are
also investigated and compared. | 1209.6494v2 |

in cuprate superconductors, as seen experimentally in Bi_2 Sr_2 Ca_1 Cu_2 O_8+x
(BSCCO) by Lee et al. [Nature (London) 442, 546 (2006)]. A simplified model is
used of d-wave Bogoliubov quasiparticles coupled to Einstein oscillators with a
mom... | 1210.7490v2 |
2012-11-18 | Classical FEM-BEM coupling methods: nonlinearities, well-posedness, and adaptivity | We consider a (possibly) nonlinear interface problem in 2D and 3D, which is
solved by use of various adaptive FEM-BEM coupling strategies, namely the
Johnson-N\'ed\'elec coupling, the Bielak-MacCamy coupling, and Costabel's
symmetric coupling. We provide a framework to prove that the continuous as well
as the discrete ... | 1211.4225v1 |
2012-11-19 | Finite-size scaling in globally coupled phase oscillators with a general coupling scheme | We investigate a critical exponent related to synchronization transition in
globally coupled nonidentical phase oscillators. The critical exponents of
susceptibility, correlation time, and correlation size are significant
quantities to characterize fluctuations in coupled oscillator systems of large
but finite size and... | 1211.4364v1 |
2013-03-11 | Crossover between integer and fractional vortex lattices in coherently coupled two-component Bose-Einstein condensates | We study effects of the internal coherent (Rabi) coupling in vortex lattices
in two-component BECs under rotation. We find how the vortex lattices without
the Rabi coupling known before are connected to the Abrikosov lattice of
integer vortices with increasing the Rabi coupling. We find that 1) for small
Rabi couplings... | 1303.2592v3 |
2013-03-14 | On the skew-symmetric character of the couple-stress tensor | In this paper, the skew-symmetric character of the couple-stress tensor is
established as the result of arguments from tensor analysis. Consequently, the
couple-stress pseudo-tensor has a true vectorial character. The fundamental
step in this development is that the isotropic couple-stress tensor cannot
exist. | 1303.3569v2 |
2013-03-21 | Synchronization in hyperchaotic time-delayed electronic oscillators coupled indirectly via a common environment | The present paper explores the synchronization scenario of hyperchaotic
time-delayed electronic oscillators coupled indirectly via a common
environment. We show that depending upon the coupling parameters a hyperchaotic
time-delayed system can show in-phase or complete synchronization, and also
inverse-phase or anti-sy... | 1303.5339v1 |

2013-11-13 | Synchronization of Coupled Boolean Phase Oscillators | We design, characterize, and couple Boolean phase oscillators that include
state-dependent feedback delay. The state-dependent delay allows us to realize
an adjustable coupling strength, even though only Boolean signals are
exchanged. Specifically, increasing the coupling strength via the range of
state-dependent delay... | 1311.2996v2 |
2013-11-13 | BSM Theories Face Higgs Coupling data | We discuss how much Higgs couplings (including the Higgs self coupling) can
deviate from their Standard Model values, in different Beyond Standard Model
(BSM) theories, if no other BSM states are accessible at the LHC. Then, we
focus on supersymmetric theories and show that there is a connection between
the mechanism t... | 1311.3040v1 |
2013-11-25 | Existence of pulses in excitable media with nonlocal coupling | We prove the existence of fast traveling pulse solutions in excitable media
with non-local coupling. Existence results had been known, until now, in the
case of local, diffusive coupling and in the case of a discrete medium, with
finite-range, non-local coupling. Our approach replaces methods from geometric
singular pe... | 1311.6508v1 |
2014-04-08 | Coupled Matrix Factorization within Non-IID Context | Recommender systems research has experienced different stages such as from

IID, namely independent and identically distributed, and (2) focusing on
specific aspects su... | 1404.7467v2 |

Wang's coupling to th... | 1407.5426v1 |
2014-08-29 | High fidelity quantum state transfer in electromechanical systems with intermediate coupling | Hybrid quantum systems usually consist of two or more subsystems, which may
take the advantages of the different systems. Recently, the hybrid system
consisting of circuit electromechanical subsystems have attracted great
attention due to its advanced fabrication and scalable integrated photonic
circuit techniques. Her... | 1408.7015v1 |
2014-10-01 | Resurgence and Holomorphy: From Weak to Strong Coupling | We analyze the resurgence properties of finite-dimensional exponential
integrals which are prototypes for partition functions in quantum field
theories. In these simple examples, we demonstrate that perturbation theory,
even at arbitrarily weak coupling, fails as the argument of the coupling
constant is varied. It is w... | 1410.0388v3 |
2015-05-05 | Numerical corrections to the strong coupling effective Polyakov-line action for finite T Yang-Mills theory | We consider a three-dimensional effective theory of Polyakov lines derived
previously from lattice Yang-Mills theory and QCD by means of a resummed strong
coupling expansion. The effective theory is useful for investigations of the
phase structure, with a sign problem mild enough to allow simulations also at
finite den... | 1505.01021v1 |

in the middle (MITM) optomechanical system. Using coupled-mode theory we find
that the ... | 1506.06315v1 |
2015-06-23 | Mode coupling and photon antibunching in a bimodal cavity containing a dipole-quantum-emitter | We study the effect of mode-coupling on a single-photon device in which a
dipole-quantum-emitter (DQE) is embedded in a bimodal whispering-gallery-mode
cavity (WGMC). A scatterer is used to induce mode coupling between
counter-clockwise and clockwise propagating light fields, which interact with
the DQE. In contrast to... | 1506.06889v1 |
2015-09-11 | Relational reasoning via probabilistic coupling | Probabilistic coupling is a powerful tool for analyzing pairs of
probabilistic processes. Roughly, coupling two processes requires finding an
appropriate witness process that models both processes in the same probability
space. Couplings are powerful tools proving properties about the relation
between two processes, in... | 1509.03476v2 |
