Band-center metal-insulator transition in bond-disordered graphene
Naba P. Nayak, Surajit Sarkar, Kedar Damle +1
We study the transport properties of a tight-binding model of non-interacting fermions with random hopping on the honeycomb lattice. At the particle-hole symmetric chemical potenti…
Finite-size prethermalization at the chaos-to-integrable crossover
Johannes Dieplinger, Soumya Bera
We investigate the infinite temperature dynamics of the complex Sachdev-Ye-Kitaev model (SYK) complimented with a single particle hopping term (SYK), leading to the chaos-t…
The internal clock of many-body delocalization
Ferdinand Evers, Ishita Modak, Soumya Bera
After a decade of many claims to the opposite, there now is a growing consensus that generic disordered quantum wires, e.g. the XXZ-Heisenberg chain, do not exhibit many-body local…
An SYK-inspired model with density-density interactions: spectral & wave function statistics, Green's function and phase diagram
Johannes Dieplinger, Soumya Bera, Ferdinand Evers
The Sachdev-Ye-Kitaev (SYK) model is a rare example of a strongly-interacting system that is analytically tractable. Tractability arises because the model is largely structureless…
Quartic multifractality and finite-size corrections at the spin quantum Hall transition
Martin Puschmann, Daniel Hernangómez-Pérez, Bruno Lang +2
The spin quantum Hall (or class C) transition represents one of the few localization-delocalization transitions for which some of the critical exponents are known exactly. Not know…
Dephasing in strongly disordered interacting quantum wires
Sourav Nandy, Ferdinand Evers, Soumya Bera
Many-body localization is a fascinating theoretical concept describing the intricate interplay of quantum interference, i.e. localization, with many-body interaction induced dephas…
