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
Hilbert space fragmentation, as it is currently investigated, primarily originates from specific kinematic constraints or emergent conservation laws in many-body systems with trans…
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…
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…
