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…
