Periodic dynamics in an Ising chain with a quadratic transverse field
H. P. Zhang, Z. Song
A quadratic well plays a central role in a wide variety of modern physical theories and applications. In this work, we investigate many-body dynamics in a quadratic well, using an…

Extended Wannier-Stark ladder and particle-pair Bloch oscillations in dimerized non-Hermitian systems
H. P. Zhang, Z. Song
In the Hermitian regime, the Wannier-Stark ladder characterizes the eigenstates of an electron in a periodic potential with an applied static electric field. In this work, we exten…
