Exploring the properties of quantum scars in a toy model
Sudip Sinha, S. Sinha
We introduce the concept of ergodicity and explore its deviation caused by quantum scars in an isolated quantum system, employing a pedagogical approach based on a toy model. Quant…

Excitation Spectra of Correlated Lattice Bosons in a Confining Trap
Dmitry L. Kovrizhin, G. Venketeswara Pai, Subhasis Sinha
We consider ultracold bosonic atoms in an optical lattice with an external trapping potential. To study the excitation energies of the resulting Bose-Hubbard model, we develop a me…
