2015-02-16 | Role of nonlinear anisotropic damping in the magnetization dynamics of topological solitons | The consequences of nonlinear anisotropic damping, driven by the presence of
Rashba spin-orbit coupling in thin ferromagnetic metals, are examined for the
dynamics of topological magnetic solitons such as domain walls, vortices, and
skyrmions. The damping is found to affect Bloch and N\'eel walls differently in

Phys. Rev. A 59, 4087 (1999)) and by others in various two-level spin systems

magnetic tunnel junction. Thanks to the large associated resistance variations
we are able to analyze quantitatively the resonant properties of these single
nanoscale magnet... | 1508.04043v1 |
2016-04-27 | Influence of nonlocal damping on the field-driven domain wall motion | We derive the complete expression of nonlocal damping in noncollinear
magnetization due to the nonuniform spin current pumped by precessional
magnetization and incorporate it into a generalized Thiele equation to study
its effects on the dynamics of the transverse and vortex domain walls (DWs) in
ferromagnetic nanowire... | 1604.07971v2 |

the Higgs amplitude mode in superconductors by means of non-equilibrium
dynamical mean-field simulations of the Holstein model. In contrast to the BCS
dynamics, we find that the damping of the Higgs mode strongly depends on the
temperature, be... | 1604.08073v2 |
2016-05-29 | Damped Infinite Energy Solutions of the 3D Euler and Boussinesq Equations | We revisit a family of infinite-energy solutions of the 3D incompressible
Euler equations proposed by Gibbon et al. [9] and shown to blowup in finite
time by Constantin [6]. By adding a damping term to the momentum equation we
examine how the damping coefficient can arrest this blowup. Further, we show
that similar inf... | 1605.08965v3 |

one-qubit Markovian channels with respect to coherence in terms of the
$l_{1}$-norm, the R$\acute{e}$nyi $\alpha$-relative entropy and the Tsallis

2017-01-19 | Decoherence effects on multiplayer cooperative quantum games | We study the behavior of cooperative multiplayer quantum games [35,36] in the
presence of decoherence using different quantum channels such as amplitude
damping, depolarizing and phase damping. It is seen that the outcomes of the
games for the two damping channels with maximum values of decoherence reduce to
same value... | 1701.05342v1 |
2017-07-30 | Blow-up for semilinear damped wave equations with sub-Strauss exponent in the scattering case | It is well-known that the critical exponent for semilinear damped wave
equations is Fujita exponent when the damping is effective. Lai, Takamura and
Wakasa in 2017 have obtained a blow-up result not only for super-Fujita
exponent but also for the one closely related to Strauss exponent when the
damping is scaling invar... | 1707.09583v3 |
2017-10-09 | Resonant absorption of surface sausage and surface kink modes under photospheric conditions | We study the effect of resonant absorption of surface sausage and surface
kink modes under photospheric conditions where the slow surface sausage modes
undergo resonant damping in the slow continuum and the surface kink modes in
the slow and Alfv\'{e}n continua at the transitional layers. We use recently

2018-03-23 | A conservation law with spatially localized sublinear damping | We consider a general conservation law on the circle, in the presence of a
sublinear damping. If the damping acts on the whole circle, then the solution
becomes identically zero in finite time, following the same mechanism as the
corresponding ordinary differential equation. When the damping acts only
locally in space,... | 1803.08767v1 |
2019-03-06 | Microwave magnon damping in YIG films at millikelvin temperatures | Magnon systems used in quantum devices require low damping if coherence is to
