Nonlinear Landau-Zener Tunneling with Heat-Bath Colored Noise
Yi Cao, Jie Liu
In this work, we investigate the influence of colored noise originating from a heat bath on nonlinear Landau-Zener (LZ) tunneling. The nonlinearity might arise intrinsically from m…
Nonreciprocal Landau-Zener Tunneling in the Presence of Heat-Bath-Induced Colored Noise
Yi Cao, Jie Liu
In this work, we investigate the effects of heat-bath-induced colored noise on nonreciprocal Landau-Zener tunneling. We perform numerical calculations of the instantaneous energy l…
Near-Resonance-Induced Caustics and Scaling Laws in a Quantum Kicked Rotor
Yi Cao, Shaowen Lan, Bin Sun +1
In this study, we investigate the dynamics of the quantum kicked rotor in the near-resonant regime and observe distinct caustic structures, such as recurring cusps, cusp oscillatio…
Bloch Oscillation and Landau-Zener Tunneling of a Periodically Kicked Dirac Particle
Bin Sun, Shaowen Lan, Yi Cao +1
We investigate the dynamics of a relativistic spin- particle governed by a one-dimensional time-periodic kicking Dirac equation. We observe distinct oscillatory behavi…
