2017-03-05 | Protecting a nuclear spin from a noisy electron spin in diamond | Although a nuclear spin is weakly coupled to its environment, due to its
small gyromagnetic ratio, its coherence time is limited by the hyperfine

2016-11-11 | Chimera states and the interplay between initial conditions and non-local coupling | Chimera states are complex spatio-temporal patterns that consist of
coexisting domains of coherent and incoherent dynamics. We study chimera states
in a network of non-locally coupled Stuart-Landau oscillators. We investigate
the impact of initial conditions in combination with non-local coupling. Based
on an analytica... | 1611.03771v1 |

waveguide lasers enabled by parity-time (PT) symmetry. The PT symmetric laser
operates on coupled waveguide cavities with electrically tuned gain and loss.
Such counterintuitive waveguide design enables PT symmetric breaking, causing
unique mode sele... | 1611.07888v3 |
2017-04-06 | Origin of Temperature Gradient in Nonequilibrium Steady States in Weakly Coupled Quantum Spin Systems | We study nonequilibrium steady states (NESSs) in quantum spin-1/2 chains in
contact with two heat baths at different temperatures. We consider the
weak-coupling limit both for spin-spin coupling in the system and for
system-bath coupling. This setting allows us to treat NESSs with a nonzero
temperature gradient analyti... | 1704.01731v1 |
2017-12-31 | Stabilization of the weakly coupled wave-plate system with one internal damping | This paper is addressed to a stabilization problem of a system coupled by a
wave and a Euler-Bernoulli plate equation. Only one equation is supposed to be

shown that sufficiently smooth solutions of the system decay logarithmically at
infinit... | 1801.00232v1 |
2017-12-21 | Exploring cogging free magnetic gears | The coupling of two rotating spherical magnets is investigated

of the so called cogging free couplings. The experiment makes use of standard
equipment and digital im... | 1801.03416v2 |
2018-01-17 | Phase-flip bifurcation and synchronous transition in unidirectionally coupled parametrically excited pendula | Phase-flip bifurcation plays an important role in the transition to
synchronization state in unidirectionally coupled parametrically excited
pendula. In coupled identical system it is the cause of complete
synchronization whereas in case of coupled non-identical system it causes
desynchronization. In coupled identical ... | 1801.05572v1 |
2018-08-20 | CU-Net: Coupled U-Nets | We design a new connectivity pattern for the U-Net architecture. Given
several stacked U-Nets, we couple each U-Net pair through the connections of
their semantic blocks, resulting in the coupled U-Nets (CU-Net). The coupling
connections could make the information flow more efficiently across U-Nets. The
feature reuse ... | 1808.06521v1 |

attainable slow-light enhancement of gain itself and to strongly affect the
mode selection in Ph... | 1906.03638v1 |
2019-07-12 | Non-coupling from the past | The method of 'coupling from the past' permits exact sampling from the
invariant distribution of a Markov chain on a finite state space. The coupling

coalescence of all trajectories. The issue of the coalescence or
non-coalescence of trajectories of ... | 1907.05605v2 |
2020-01-09 | Theoretical Prediction of Magnetic Exchange Coupling Constants from Broken-Symmetry Coupled Cluster Calculations | Exchange coupling constants ($J$) are fundamental to the understanding of
spin spectra of magnetic systems. Here we investigate the broken-symmetry (BS)

fashion conv... | 2001.03226v1 |
2020-05-09 | Synchronization of oscillators not sharing a common ground | Networks of coupled LC oscillators that do not share a common ground node are

2020-07-09 | Splitting schemes for a Lagrange multiplier formulation of FSI with immersed thin-walled structure: stability and convergence analysis | The numerical approximation of incompressible fluid-structure interaction
problems with Lagrange multiplier is generally based on strongly coupled

transform method is ext... | 2104.14814v1 |
2021-05-03 | Anisotropy-Exchange Resonance as a Mechanism for Entangled State Switching | We explore the three-particle spin model of an $S_{1}=\frac{1}{2}$ particle
(e.g. a stationary electron) interacting with two spin-coupled $S_{\text{2,3}}$
particles with exchange coupling and magnetic anisotropy. We find that in the
case of $S_{2,3}=1$ particles, the coupled particle entanglement states can be

2021-05-23 | Impact of non-Hermitian Mode interaction on Inter-cavity Light transfer | Understanding inter-site mutual mode interaction in coupled physical systems
is essential to comprehend large compound systems as this local interaction
determines the successive multiple inter-site energy transfer efficiency. We
demonstrate that only the non-Hermitian coupling can correctly account for the
light trans... | 2105.10936v1 |
2021-06-30 | The Performance Impact of Newton Iterations per Solver Call in Partitioned Fluid-Structure Interaction | The cost of a partitioned fluid-structure interaction scheme is typically
assessed by the number of coupling iterations required per time step, while
ignoring the Newton loops within the nonlinear sub-solvers. In this work, we
discuss why these single-field iterations deserve more attention when
evaluating the coupling... | 2106.15930v1 |
2021-07-09 | Theory of Vibrational Polariton Chemistry in the Collective Coupling Regime | We theoretically demonstrate that chemical reaction rate constant can be
significantly suppressed by coupling molecular vibrations with an optical

modification of the rate constant. When a reaction coordinate is strongly
coupled to the solv... | 2107.04156v1 |
2021-08-03 | Two electrons in harmonic confinement coupled to light in a cavity | The energy and wave function of a harmonically confined two-electron system

demonstrate that in the presence of Rashba spin-orbit coupling, it couples
linearly with an external exchange field. The Higgs-spin coupling dramatically
modifies the spin susceptibility near the superconducting critical temperature
and consequently ... | 2108.06202v2 |
2021-10-05 | Revisiting closed asymptotic couples | Every discrete definable subset of a closed asymptotic couple with ordered
scalar field $\boldsymbol k$ is shown to be contained in a finite-dimensional
$\boldsymbol k$-linear subspace of that couple. It follows that the
