Many-body critical phase in a quasiperiodic chain and dynamical Widom lines in Fock space properties
Nilanjan Roy, Subroto Mukerjee, Sumilan Banerjee
We study a quasiperiodic model in one dimension, namely the extended Aubry-André-Harper (EAAH) chain, that realizes a critical phase comprising entirely single-particle critical st…

Supervised and unsupervised learning of the many-body critical phase, phase transitions, and critical exponents in disordered quantum systems
Aamna Ahmed, Nilanjan Roy
In this work, we begin by questioning the existence of a new kind of nonergodic extended phase, namely, the many-body critical (MBC) phase in finite systems of an interacting quasi…

Topological quantum phase transitions and criticality in a longer-range Kitaev chain
Y R Kartik, Ranjith R Kumar, S Rahul +2
In an attempt to theoretically investigate the quantum phase transition and criticality in topological models, we study Kitaev chain with longer-range couplings (finite number of n…
