Unbound States and Mixed Bound--Unbound Phases in Near-Infinitely Deep Potentials
Shujie Cheng, Tong Liu, Gao Xianlong
We investigate the robustness of unbound states in one-dimensional quasiperiodic models with near-infinitely deep potentials. By constructing a deeper extension of the Liu-Xia mode…

Thermodynamic modes of a quasiperiodic mobility-edge system in a quantum Otto cycle
Ao Zhou, Shujie Cheng, Gao Xianlong
We investigate thermodynamic operation of a quasiperiodic lattice with an exact mobility edge, described by the Biddle--Das Sarma model. We use this model as the working medium of…

Wigner distribution, Wigner entropy and Quantum Refrigerator of a One-Dimensional Off-diagonal Quasicrystal
Shan Suo, Ao Zhou, Yanting Chen +2
We investigate an off-diagonal quasicrystal featuring simultaneous off-diagonal and diagonal quasiperiodic modulations. By analyzing the fractal dimension, we map out the delocaliz…
