Coexistence of distinct mobility edges in a 1D quasiperiodic mosaic model
Xu Xia, Weihao Huang, Ke Huang +2
We introduce a one-dimensional quasiperiodic mosaic model with analytically solvable mobility edges that exhibit different phase transitions depending on the system parameters. Spe…
Many-body phase transitions in a non-Hermitian Ising chain
Chao-Ze Lu, Xiaolong Deng, Su-Peng Kou +1
We study many-body phase transitions in a one-dimensional ferromagnetic transversed field Ising model with an imaginary field and show that the system exhibits three phase transiti…
Superdiffusion in random two dimensional system with time-reversal symmetry and long-range hopping
Xiaolong Deng, Ivan M. Khaymovich, Alexander L. Burin
Although it is recognized that Anderson localization takes place for all states at a dimension less or equal , while delocalization is expected for hopping decreasing…
Duality in power-law localization in disordered one-dimensional systems
X. Deng, V. E. Kravtsov, G. V. Shlyapnikov +1
The transport of excitations between pinned particles in many physical systems may be mapped to single-particle models with power-law hopping, . For randomly spaced particle…
Quantum Levy flights and multifractality of dipolar excitations in a random system
X. Deng, B. L. Altshuler, G. V. Shlyapnikov +1
We consider dipolar excitations propagating via dipole-induced exchange among immobile molecules randomly spaced in a lattice. The character of the propagation is determined by lon…
Quantum phases of interacting phonons in ion traps
X. -L. Deng, D. Porras, J. I. Cirac
The vibrations of a chain of trapped ions can be considered, under suitable experimental conditions, as an ensemble of interacting phonons, whose quantum dynamics is governed by a…
