Excitation spectra of quantum matter without quasiparticles II: random - models
Maria Tikhanovskaya, Haoyu Guo, Subir Sachdev +1
We present numerical solutions of the spectral functions of - models with random and all-to-all exchange and global SU() spin rotation symmetry. The solutions are obtained…
Excitation spectra of quantum matter without quasiparticles I: Sachdev-Ye-Kitaev models
Maria Tikhanovskaya, Haoyu Guo, Subir Sachdev +1
We study the low frequency spectra of complex Sachdev-Ye-Kitaev (SYK) models at general densities. The analysis applies also to SU() magnets with random exchange at large . T…
Fate of Majorana zero modes, critical states and non-conventional real-complex transition in non-Hermitian quasiperiodic lattices
Tong Liu, Shujie Cheng, Hao Guo +1
We study a one-dimensional -wave superconductor subject to non-Hermitian quasiperiodic potentials. Although the existence of the non-Hermiticity, the Majorana zero mode is still…
Generalized Aubry-André self-duality and Mobility edges in non-Hermitian quasi-periodic lattices
Tong Liu, Hao Guo, Yong Pu +1
We demonstrate the existence of generalized Aubry-André self-duality in a class of non-Hermitian quasi-periodic lattices with complex potentials. From the self-duality relations, t…
Ubiquity of zeros of Loschmidt amplitude for mixed states in different physical processes and their implications
Xu-Yang Hou, Qu-Cheng Gao, Hao Guo +3
The Loschmidt amplitude of the purified states of mixed-state density matrices is shown to have zeros when the system undergoes a quasistatic, quench, or Uhlmann process. While the…
Thermostatistics of a q-deformed Relativistic Ideal Fermi Gas
Xu-Yang Hou, H. Yan, Hao Guo
In this paper, we formulate a q-deformed many-body theory for the relativistic Fermi gas and discuss the effects of the deformation parameter q on physical properties of such syste…
