Eigenstate thermalization at the edge of the many-body spectrum
Arnav Pushkar, Pranay Patil, Soumya Bera +2
It is well-known that thermalization breaks down in presence of an extensive number of symmetries or conservation laws that are mutually compatible or commuting with each other. We…
Distinguishing dynamical quantum criticality through local fidelity distances
Ruchira V Bhat, Soumya Bera
Using local quantum fidelity distances, we study the dynamical quantum phase transition in integrable and non-integrable one-dimensional Ising chains. Unlike the Loschmidt echo, th…
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…
