Hamiltonian fingerprints of a collective mode across the BCS-BEC crossover
Yogeshwar Prasad
Collective excitations can survive profound changes in the microscopic degrees of freedom that generate them. We track a layer-odd collective response from an exact weak-coupling h…

Finite temperature study of correlations in bilayer band-insulator
Yogeshwar Prasad
We perform the finite-temperature determinant quantum Monte Carlo simulation for the attractive Hubbard model on the half-filled bilayer square lattice. Recent progress on optical…
