An asymptotically solvable model of many-body critical phases: mobility edges, scars, and inverted scars
Yi-Ting Tu, Zi-Jian Li, Sankar Das Sarma
While the prethermal regime of random many-body localized (MBL) systems is dominated by accidental many-body resonances, another class of resonances, originating from the underlyin…

Wigner solid or Anderson solid -- 2D electrons in strong disorder
Aryaman Babbar, Zi-Jian Li, Sankar Das Sarma
Critically analyzing recent STM and transport experiments [Z. Ge, et al, arXiv:2510.12009] on 2D electron systems in the presence of random quenched impurities, we argue that the r…

Many-body localization in a slowly varying potential
Zi-Jian Li, Yi-Ting Tu, Sankar Das Sarma
We study many-body localization (MBL) in a nearest-neighbor hopping 1D lattice with a slowly varying (SV) on-site potential with . The corresponding non…
