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…
Flat-band-based multifractality in the all-band-flat diamond chain
Aamna Ahmed, Ajith Ramachandran, Ivan M. Khaymovich +1
We study the effect of quasiperiodic Aubry-André disorder on the energy spectrum and eigenstates of a one-dimensional all-bands-flat (ABF) diamond chain. The ABF diamond chain poss…
Non-Hermitian Rosenzweig-Porter random-matrix ensemble: Obstruction to the fractal phase
Giuseppe De Tomasi, Ivan M. Khaymovich
We study the stability of non-ergodic but extended (NEE) phases in non-Hermitian systems. For this purpose, we generalize a so-called Rosenzweig-Porter random-matrix ensemble (RP),…
Sub-diffusive Thouless time scaling in the Anderson model on random regular graphs
Luis Colmenarez, David J. Luitz, Ivan M. Khaymovich +1
The scaling of the Thouless time with system size is of fundamental importance to characterize dynamical properties in quantum systems. In this work, we study the scaling of the Th…
