2015-06-13 | General coupled mode theory in non-Hermitian waveguides | In the presence of loss and gain, the coupled mode equation on describing the
mode hybridization of various waveguides or cavities, or cavities coupled to
waveguides becomes intrinsically non-Hermitian. In such non-Hermitian
waveguides, the standard coupled coupled mode theory fails. We generalize the
coupled mode theo... | 1506.04224v3 |
2015-06-13 | Circuit electromechanics with single photon strong coupling | In circuit electromechanics, the coupling strength is usually very small.
Here, replacing the capacitor in circuit electromechanics by a superconducting
flux qubit, we show that the coupling among the qubit and the two resonators
can induce effective electromechanical coupling which can attain the strong
coupling regim... | 1506.04247v2 |
2015-06-16 | Coupling the Kolmogorov Diffusion: maximality and efficiency considerations | This is a case study concerning the rate at which probabilistic coupling
occurs for nilpotent diffusions. We focus on the simplest case of Kolmogorov
diffusion (Brownian motion together with its time integral, or, slightly more
generally, together with a finite number of iterated time integrals). In this
case there can... | 1506.04804v3 |
2015-06-30 | Scalar - Tensor gravity with scalar -matter direct coupling and its cosmological probe | SNIA and CMB datasets have shown both of evolving Newton's "constant" and a
signature of the coupling of scalar field to matter. These observations
motivate the consideration of the scalar-matter coupling in Jordan frame in the
framework of scalar-tensor gravity. So far, majority of the works on the
coupling of scalar ... | 1506.09121v1 |

the exciton-plasmon coupling strength up to 58 meV at 77 K, which also survives
at room temper... | 1511.03750v1 |
2016-04-04 | Hindered magnetic dipole transitions between P-wave bottomonia and coupled-channel effects | In the hindered magnetic dipole transitions of heavy quarkonia, the
coupled-channel effects originating from the coupling of quarkonia to a pair of
heavy and anti-heavy mesons can play a dominant role. Here, we study the
hindered magnetic dipole transitions between two $P$-wave bottomonia, $\chi_b(n
P)$ and $h_b(n^\pri... | 1604.00770v2 |

state in coupled oscillators, both limit cycle and chaotic, under cyclic
coupling and diffusive coupling as well when an asymmetry is introduced in
terms of a negative parameter mismatch. Such a transition appears in limit
cycle systems via pi... | 1604.07943v1 |
2016-06-01 | Pure plate bending in couple stress theories | In this paper, we examine the pure bending of plates within the framework of
modified couple stress theory (M-CST) and consistent couple stress theory
(C-CST). In this development, it is demonstrated that M-CST does not describe
pure bending of a plate properly. Particularly, M-CST predicts no
couple-stresses and no si... | 1606.02954v1 |
2016-06-16 | Energy Conservation and Coupling Error Reduction in Non-Iterative Co-Simulations | When simulators are energetically coupled in a co-simulation, residual
energies alter the total energy of the full coupled system. This distorts the
system dynamics, lowers the quality of the results, and can lead to
instability. By using power bonds to realize simulator coupling, the
Energy-Conservation-based Co-Simul... | 1606.05168v1 |
2016-07-01 | Dynamical strong coupling and parametric amplification in mechanical modes of graphene drums | Mechanical resonators are ubiquitous in modern information technology. With
the ability to couple them to electromagnetic and plasmonic modes, they hold

technology. Graphene based resonators are of interest for technological
applications due to the... | 1607.00229v1 |
2017-02-28 | Linking Magnon-Cavity Strong Coupling to Magnon-Polaritons through Effective Permeability | Strong coupling in cavity-magnon systems has shown great potential for use in
spintronics and information processing technologies due to the low damping
rates and long coherence times. Although such systems are conceptually similar
to those coupled by magnon-polaritons (MPs), the link between magnon-cavity
coupling and... | 1703.00074v1 |
2017-03-04 | Interpolated energy densities, correlation indicators and lower bounds from approximations to the strong coupling limit of DFT | We investigate the construction of approximated exchange-correlation
functionals by interpolating locally along the adiabatic connection between the
weak- and the strong-coupling regimes, focussing on the effect of using
approximate functionals for the strong-coupling energy densities. The gauge

linear and nonlinear loss-gain profiles which can facilitate power saturation.

2018-02-26 | Cavity quantum-electrodynamical polaritonically enhanced electron-phonon coupling and its influence on superconductivity | Laser control of solids was so far mainly discussed in the context of strong
classical nonlinear light-matter coupling in a pump-probe framework. Here we
propose a quantum-electrodynamical setting to address the coupling of a
low-dimensional quantum material to quantized electromagnetic fields in quantum
cavities. Usin... | 1802.09437v2 |
2018-04-11 | Novel matter coupling in general relativity via canonical transformation | We study canonical transformations of general relativity (GR) to provide a
novel matter coupling to gravity. Although the transformed theory is equivalent
to GR in vacuum, the equivalence no longer holds if a matter field minimally
couples to the canonically transformed gravitational field. We find that a
naive matter ... | 1804.03902v2 |

observed through transient uncoupling in a class of unidirectionally coupled
identical chaotic systems. The phenomenon of transient uncoupling implies the
clipping of the chaotic attractor of the driven system in a drive-driven
scenario and makin... | 1811.05091v1 |

2014-03-18 | Optomechanical-like coupling between superconducting resonators | We propose and analyze a circuit that implements a nonlinear coupling between
two superconducting microwave resonators. The resonators are coupled through a
superconducting quantum interference device (SQUID) that terminates one of the
resonators. This produces a nonlinear interaction on the standard
optomechanical for... | 1403.4341v1 |
2017-01-25 | Suppression and Revival of Oscillations through Time-varying Interaction | We explore the dynamical consequences of switching the coupling form in a
system of coupled oscillators. We consider two types of switching, one where
the coupling function changes periodically and one where it changes
probabilistically. We find, through bifurcation diagrams and Basin Stability
analysis, that there exi... | 1701.07314v1 |

the compensating ferrimagnet gadolinium iron garnet (GdIG) and a
three-dimensional microwave cavity. The temperature is varied in order to tune
the GdIG magnetization and to observe the transition from the weak coupling
regime to the strong co... | 1701.08969v3 |

configurations, where the coupling strength J (or photon hopping) is extracted
from the ... | 1805.03012v1 |
2018-05-09 | Exact explosive synchronization transitions in Kuramoto oscillators with time-delayed coupling | Synchronization commonly occurs in many natural and man-made systems, from
neurons in the brain to cardiac cells to power grids to Josephson junction
arrays. Transitions to or out of synchrony for coupled oscillators depend on
several factors, such as individual frequencies, coupling, interaction time
delays and networ... | 1805.03510v1 |
2018-05-10 | Synchrony and Anti-Synchrony for Difference-Coupled Vector Fields on Graph Network Systems | We define a graph network to be a coupled cell network where there are only
one type of cell and one type of symmetric coupling between the cells. For a
difference-coupled vector field on a graph network system, all the cells have
the same internal dynamics, and the coupling between cells is identical,
symmetric, and d... | 1805.04144v2 |
2009-12-16 | Phase locking of coupled lasers with many longitudinal modes | Detailed experimental and theoretical investigations on two coupled fiber
lasers, each with many longitudinal modes, reveal that the behavior of the
longitudinal modes depends on both the coupling strength as well as the
detuning between them. For low to moderate coupling strength only longitudinal
modes which are comm... | 0912.3235v1 |
