Measurement-induced phase transitions in -dimensional stabilizer circuits

P Sierant, M Schirò, M Lewenstein, X Turkeshi - Physical Review B, 2022 - APS

Measuring nonstabilizerness via multifractal flatness

X Turkeshi, M Schirò, P Sierant - Physical Review A, 2023 - APS
Universal quantum computing requires nonstabilizer (magic) quantum states. Quantifying
the nonstabilizerness and relating it to other quantum resources is vital for characterizing the …

Rare thermal bubbles at the many-body localization transition from the Fock space point of view

G De Tomasi, IM Khaymovich, F Pollmann, S Warzel - Physical Review B, 2021 - APS
In this paper we study the many-body localization (MBL) transition and relate it to the
eigenstate structure in the Fock space. Besides the standard entanglement and multifractal …

Absence of slow particle transport in the many-body localized phase

DJ Luitz, YB Lev - Physical Review B, 2020 - APS
We analyze the saturation value of the bipartite entanglement and number entropy starting
from a random product state deep in the many-body localized (MBL) phase. By studying the …

Absence of mobility edge in short-range uncorrelated disordered model: Coexistence of localized and extended states

AK Das, A Ghosh, IM Khaymovich - Physical Review Letters, 2023 - APS
Unlike the well-known Mott's argument that extended and localized states should not coexist
at the same energy in a generic random potential, we formulate the main principles and …
