Probing Fermi surface topology by ultrafast pump pulse dynamics
Debamalya Dutta, Kush Saha
We present a dynamical approach to detect changes in Fermi surface topology in a two-band model. Specifically, we show that the system's response to a low intensity light pulse can…

Frequency-selective amplification of nonlinear response in strongly correlated bosons
Aditya Prakash, Debamalya Dutta, Arko Roy +1
We present a protocol to generate enhanced non-linear responses of incident pulses in the density wave phase within the extended Bose-Hubbard model using the concept of resonance-i…

Non-linear response of interacting bosons in a quasiperiodic potential
Debamalya Dutta, Arko Roy, Kush Saha
We theoretically study the electric pulse-driven non-linear response of interacting bosons loaded in an optical lattice in the presence of an incommensurate superlattice potential.…
