DOI: 10.1088/1361-6382/ac0a86

Abstract: We discuss relations between the initial boundary value problem (IBVP) and quasi-local Hamiltonians in GR. The latter have traditionally been based on Dirichlet boundary conditions, which however are shown here to be ill-posed for the… read more here.

DOI: 10.1103/physrevlett.127.060602

Abstract: Eigenstate thermalization in quantum many-body systems implies that eigenstates at high energy are similar to random vectors. Identifying systems where at least some eigenstates are nonthermal is an outstanding question. In this Letter we show… read more here.

Published in 2022 at "Entropy"

DOI: 10.3390/e25010059

Abstract: OTOC has been used to characterize the information scrambling in quantum systems. Recent studies have shown that local conserved quantities play a crucial role in governing the relaxation dynamics of OTOC in non-integrable systems. In… read more here.
