Quantum States and Spectra of Small Cylindrical and Toroidal Lattices
Caelan Brooks, Kunal K. Das
We examine the spectrum and quantum states of small lattices with cylindrical and toroidal topology subject to a scalar gauge potential that introduces a position dependent phase i…

Spin Orbit and Hyperfine Simulations with Two-Species Ultracold Atoms in a Ring
Allison Brattley, Tomáš Opatrný, Kunal K. Das
A collective spin model is used to describe two species of mutually interacting ultracold bosonic atoms confined to a toroidal trap. The system is modeled by a Hamiltonian that can…

Effects of a rotating periodic lattice on coherent quantum states in a ring topology: The case of negative nonlinearity
Jonathan Tekverk, Christopher Siebor, Kunal K. Das
We study the spectrum and stationary states in a ring-shaped lattice potential in the context of ultracold atoms with attractive interatomic interactions. We determine analytical s…
