Non-Hermitian Stark Many-Body Localization
Han-Ze Li, Xue-Jia Yu, Jian-Xin Zhong
Utilizing exact diagonalization (ED) techniques, we investigate a one-dimensional, non-reciprocal, interacting hard-core boson model under a Stark potential with tail curvature. By…
One-photon Solutions to Multiqubit Multimode quantum Rabi model
Jie Peng, Juncong Zheng, Jing Yu +6
General solutions to the quantum Rabi model involve subspaces with unbounded number of photons. However, for the multiqubit multimode case, we find special solutions with at most o…
Unified Superradiant phase transitions
Jie Peng, Enrique Rico, Jianxin Zhong +2
We prove, by means of a unified treatment, that the superradiant phase transitions of Dicke and classical oscillator limits of simple light-matter models are indeed of the same typ…
Morphological Symmetry Breaking During Epitaxial Growth at Grazing Incidence
Jianxin Zhong, Enge Wang, Qian Niu +1
It is shown that, in submonolayer growth at off-normal incidence, even much less than one percent of transfer from the condensation energy of the deposited atoms into adatom motion…
Dynamical Scaling Properties of Electrons in Quantum Systems with Multifractal Eigenstates
Jianxin Zhong, Zhenyu Zhang, Michael Schreiber +2
We study the intricate relationships between the dynamical scaling properties of electron wave packets and the multifractality of the eigenstates in quantum systems. Numerical simu…
Energy Levels of Quasiperiodic Hamiltonians, Spectral Unfolding, and Random Matrix Theory
Michael Schreiber, Uwe Grimm, Rudolf A. Roemer +1
We consider a tight-binding Hamiltonian defined on the quasiperiodic Ammann-Beenker tiling. Although the density of states (DOS) is rather spiky, the integrated DOS is quite smooth…
