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…
Stripe-tuned superconductivity in single-flavor metals with nontrivial quantum geometry
Yi-Ting Tu, Yang-Zhi Chou, Yi Huang +1
We study how the interplay between nontrivial quantum geometry and an applied stripe potential affects superconductivity in a two-dimensional single-flavor metal. Assuming a weak c…
Coherently synchronized oscillations in many-body localization
Zi-Jian Li, Yi-Ting Tu, Sankar Das Sarma
We find an unexpected phenomenon of coherently synchronized oscillations in a mirror-symmetric many-body localized system. A synchronization transition of the spin oscillations is…
Conventional and practical metallic superconductivity arising from repulsive Coulomb coupling
Sankar Das Sarma, Jay D. Sau, Yi-Ting Tu +1
A concrete question is discussed: Can there be conventional s-wave superconductivity in regular 3D (or 2D) metals, i.e., electrons in a jellium background, interacting via the stan…
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…
