Destructive Interference induced constraints in Floquet systems
Somsubhra Ghosh, Indranil Paul, K. Sengupta +1
We introduce the paradigm of destructive many-body interference between quantum trajectories as a means to systematically generate prethermal kinetically constrained dynamics in Fl…
Magnon-Phonon Coupling in Layered Antiferromagnet
Somsubhra Ghosh, Mainak Palit, Sujan Maity +1
We present a fully analytical model of hybridization between magnon, and phonons observed experimentally in magneto-Raman scattering in van der Waals (vdW) antiferromagnets (AFM).…
Signatures of fragmentation for periodically driven fermions
Somsubhra Ghosh, Indranil Paul, K. Sengupta
We study the possible signatures of prethermal strong Hilbert space fragmentation (HSF) for one-dimensional (1D) fermions subjected to a periodic drive. We extend the results of Ph…
Hilbert space fragmentation imposed real spectrum of non-Hermitian systems
Somsubhra Ghosh, K. Sengupta, Indranil Paul
We show that constraints imposed by strong Hilbert space fragmentation (HSF) along with the presence of certain global symmetries can ensure the reality of eigenspectra of non-Herm…
Detecting prethermal Floquet phases of Rydberg atom arrays
Somsubhra Ghosh, Diptiman Sen, K. Sengupta
We study the prethermal Floquet phases of a two-dimensional (2D) Rydberg atom array on a rectangular lattice in the presence of a periodic drive with large drive amplitude. We deri…
Prethermal fragmentation in a periodically driven Fermionic chain
Somsubhra Ghosh, Indranil Paul, K. Sengupta
We study a Fermionic chain with nearest-neighbor hopping and density-density interactions, where the nearest-neighbor interaction term is driven periodically. We show that such a d…
Anisotropic Magnetodielectric Coupling in Layered Antiferromagnetic FePS
Anudeepa Ghosh, Magdalena Birowska, Pradeepta Kumar Ghose +9
We report anisotropic magnetodielectric (MD) coupling in layered van der Waals (vdW) antiferromagnetic (AFM) FePS (Néel temperature 120K) with perpendic…
Hinge mode dynamics of periodically driven higher-order Weyl semimetals
Somsubhra Ghosh, Kush Saha, K. Sengupta
We study the stroboscopic dynamics of hinge modes of a second-order topological material modeled by a tight-binding free fermion Hamiltonian on a cubic lattice in the intermediate…
