We investigate the quantum random walk in momentum space of a spinor kicked rotor with non-Hermitian kicking potential. find that variance distributions transitions from quadratic to linear growth over time for case. Correspondingly, are shape Gaussian wavepackets, providing clear evidence classical induced by non-Hermitian-driven Remarkably, rate diverges as parameter approaches zero. In Hermitian case, deviations resonance condition dramatically suppress variance, leading dynamical...
We investigate the properties of mobility edge in an Aubry-André-Harper model with nonreciprocal long-range hopping.The results reveal that there can be a new type featuring both strength-dependent and scale-free properties.By calculating fractal dimension, we find positions edges are robust to strength non-reciprocal hopping.Furthermore, through scale analysis observables such as eigenenergy eigenstate, etc., show four different specific observed system.This paper extends family tree...
We study a frequency-dependent damping model of hyperdiffusion within the generalized Langevin equation. The allows for colored noise defined by its spectral density, assumed to be proportional ω^{δ-1} at low frequencies with 0<δ<1 (sub-Ohmic damping) or 1<δ<2 (super-Ohmic damping), where is deduced from means fluctuation-dissipation theorem. It shown that super-Ohmic and certain parameters, diffusive process particle in titled periodic potential undergos sequentially four time regimes:...
We study numerically and analytically the barrier escape dynamics of a particle driven by an underlying correlated Lévy noise for smooth metastable potential. A “quasi-monochrome-color” noise, i.e., first-order derivative variable linear second-order differential equation subjected to symmetric α-stable white also called harmonic velocity is proposed. Note that time-integral Green function this kind equal zero. This leads existence negative time correlation implies step in one direction...

The application of DDA method is used to compute the optical forces exerted on irregular inhomogeneous particles induced by a non-paraxial Airy laser-sheet using vector angular spectrum decomposition method.
Electromagnetic scattering of a core-shell sphere, such as PM2.5, by vector Bessel beam is investigated using the discrete-dipole approximation (DDA) method. The extinction and absorption efficiencies are calculated, effects particle parameters including inner diameter, equivalent radius offset core along coordinate axis discussed.
DDA method is used to compute scattering properties of various cube-shaped particles induced by different kinds Airy light-sheets. The effects modulation parameter, transverse scale and beam center the sheet scattering, absorption, extinction cross-sections are investigated in this paper.
In the long-time limit, an open quantum system coupled to a dissipative environment is believed lose its coherence without driving or measurement. Counterintuitively, we provide necessary condition on trapping of two-level entirely with thermal bath. Based time-local master equation, it found that residue survives even under high-temperature bath as long Lamb shift exactly negative transition frequency. This generally met in strong and ultrastrong coupling regime could be relaxed by...
