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…
Resonance statistics, Fock-space branching, and long-range pair networks in slowly varying interacting chains
Yogeshwar Prasad
In a slowly varying aperiodic potential with random power-law density interactions , the resonant-object ensemble changes across , where…
Hartree Fragmentation and Long-Range Pair Networks in Aperiodic Chains
Yogeshwar Prasad
For fermions in a slowly varying aperiodic potential with random interactions , the potential fixes the resonance supply . On crossing …
Exact Gaussian pinning of a relative-phase mode and interaction-driven detuning from the pinned frequency
Yogeshwar Prasad
Hybridization between two identical fermionic layers or components produces a rigid bonding--antibonding splitting . We show that in a paired state this scale enters the coll…
Single-particle excitations across the localization and many-body localization transition in quasi-periodic systems
Yogeshwar Prasad, Arti Garg
We study localization and many-body localization transition in one dimensional systems in the presence of deterministic quasi-periodic potential. We use single-particle excitations…
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…
Initial State Dependent Dynamics Across Many-body Localization Transition
Y. Prasad, Arti Garg
We investigate quench dynamics across many-body localization (MBL) transition in an interacting one dimensional system of spinless fermions with aperiodic potential. We consider a…
Many-body localization and enhanced non-ergodic sub-diffusive regime in the presence of random long-range interactions
Yogeshwar Prasad, Arti Garg
We study many-body localization (MBL) in a one-dimensional system of spinless fermions with a deterministic aperiodic potential in the presence of long-range interactions decaying…
Fermionic Superfluid from a Bilayer Band Insulator in an Optical Lattice
Yogeshwar Prasad, Amal Medhi, Vijay B. Shenoy
We propose a model to realize a fermionic superfluid state in an optical lattice circumventing the cooling problem. Our proposal exploits the idea of tuning the interaction in a ch…
