Fractonic Constraints and Magnetic Order in a Dipole-Conserving Spin Chain
Prabhakar, Giuseppe De Tomasi, Soumya Bera
This work investigates the competition between dipole conservation, which imposes strong dynamical constraints and prevents the propagation of isolated spin excitations, and Ising-…
Diffusive metal in a percolating Chern insulator
Subrata Pachhal, Naba P. Nayak, Soumya Bera +1
Two-dimensional non-interacting fermions without any anti-unitary symmetries generically get Anderson localized in the presence of disorder. In contrast, topological superconductor…
Fock-space fragmentation in quenches of disordered interacting fermions
Ishita Modak, Rajesh Narayanan, Ferdinand Evers +1
Fock-space fragmentation, as it is currently investigated, primarily originates from specific kinematic constraints or emergent conservation laws in many-body systems with translat…
Critical States of Fermions with Flux Disorder
Hiranmay Das, Naba P. Nayak, Soumya Bera +1
Motivated by many contemporary problems in condensed matter physics where matter particles experience random gauge fields, we investigate the physics of fermions on a square lattic…
Disorder-induced delocalization and reentrance in a Chern-Hopf insulator
Soumya Bera, Ivan Dutta, Roderich Moessner +1
The Chern-Hopf insulator is an unconventional three-dimensional topological insulator with a bulk gap and gapless boundary states without protection from global discrete symmetries…
Inhomogeneous Floquet thermalization
Soumya Bera, Ishita Modak, Roderich Moessner
How a closed system thermalizes, especially in the absence of global conservation laws but in the presence of disorder and interactions, is one of the central questions in non-equi…
