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…
