Dynamical quantum phase transitions in Weyl semimetals
Aritra Lahiri, Soumya Bera
The quench dynamics in type-I inversion symmetric Weyl semimetals (WSM) are explored in this work which, due to the form of the Hamiltonian, may be readily extended to two-dimensio…
Multiscale entanglement clusters at the many-body localization phase transition
Loïc Herviou, Soumya Bera, Jens H. Bardarson
We study numerically the formation of entanglement clusters across the many-body localization phase transition. We observe a crossover from strong many-body entanglement in the erg…
Apparent slow dynamics in the ergodic phase of a driven many-body localized system without extensive conserved quantities
Talía L. M. Lezama, Soumya Bera, Jens H. Bardarson
We numerically study the dynamics on the ergodic side of the many-body localization transition in a periodically driven Floquet model with no global conservation laws. We describe…
Accessing eigenstate spin-glass order from reduced density matrices
Younes Javanmard, Soumya Bera, Markus Heyl
Many-body localized phases may not only be characterized by their ergodicity breaking, but can also host ordered phases such as the many-body localized spin-glass (MBL-SG). The MBL…
Sorting Fermionization from Crystallization in Many-Boson Wavefunctions
S. Bera, B. Chakrabarti, A. Gammal +5
Fermionization is what happens to the state of strongly interacting repulsive bosons interacting with contact interactions in one spatial dimension. Crystallization is what happens…
Sharp entanglement thresholds in the logarithmic negativity of disjoint blocks in the transverse-field Ising chain
Younes Javanmard, Daniele Trapin, Soumya Bera +2
Entanglement has developed into an essential concept for the characterization of phases and phase transitions in ground states of quantum many-body systems. In this work, we use th…
