Effects of a rotating periodic lattice on coherent quantum states in a ring topology: The case of positive nonlinearity
Hongyi Huang, Kunal K. Das
We study the landscape of solutions of the coherent quantum states in a ring shaped lattice potential in the context of ultracold atoms with an effective positive nonlinearity indu…
Entangled Collective Spin States of Two Species Ultracold atoms in a Ring
Tomáš Opatrný, Kunal K. Das
We study the general quantum Hamiltonian that can be realized with two species of mutually interacting degenerate ultracold atoms in a ring-shaped trap, with the options of rotatio…
Quantum Scattering States in a Nonlinear Coherent Medium
Allison Brattley, Hongyi Huang, Kunal K. Das
We present a comprehensive study of stationary states in a coherent medium with a quadratic or Kerr nonlinearity in the presence of localized potentials in one dimension (1D) for b…
Rotation Sensitive Quench and Revival of Coherent Oscillations in a Ring Lattice
Caelan Brooks, Allison Brattley, Kunal K. Das
We consider ultracold atoms trapped in a toroidal trap with an azimuthal lattice for utility as a macroscopic simulator of quantum optics phenomena. We examine the dynamics induced…
Synthetic Gauge Structures in Real Space in a Ring lattice
Kunal K. Das, Miroslav Gajdacz
Emergence of fundamental forces from gauge symmetry is among our most profound insights about the physical universe. In nature, such symmetries remain hidden in the space of intern…
Realizing the Harper model with Ultracold Atoms in a Ring Lattice
Kunal K. Das, Jacob Christ
We demonstrate that all of the salient features of the Harper-Hofstadter model can be implemented with ultracold atoms trapped in a bichromatic ring-shaped lattice. Using realistic…
