Su-Schrieffer-Heeger model driven by sequences of two unitaries: periodic, quasiperiodic, aperiodic, and random protocols
Maitri Ganguli, Diptiman Sen
We study the effect of driving the Su-Schrieffer-Heeger model using two unitary operators and in different combinations; the unitaries differ in the values of the inter…

Tunable topology, Hall response, and spin-textures in bicircularly polarized light illuminated altermagnets
Maitri Ganguli, Aneek Jana, Awadhesh Narayan
Altermagnets, featuring non-relativistic spin splitting, have drawn enormous attention due to their intriguing properties. Here, we investigate the effects of shining bicircularly…

Aspects of Hilbert space fragmentation in the quantum East model: fragmentation, subspace-restricted quantum scars, and effects of density-density interactions
Maitri Ganguli, Sreemayee Aditya, Diptiman Sen
We investigate a one-dimensional correlated-hopping model of spinless fermions with an East constraint. We first analytically unravel the complete fragmentation structure of this m…
