Interference induced anisotropy in a two-dimensional dark state optical lattice
Edvinas Gvozdiovas, Ian B. Spielman, Gediminas Juzeliūnas
We describe a two-dimensional optical lattice for ultracold atoms with spatial features below the diffraction limit created by a bichromatic optical standing wave. At every point i…
Energies and widths of Efimov states in the three-boson continuum
A. Deltuva
Three-boson Efimov physics is well known in the bound-state regime, but far less in the three-particle continuum at negative two-particle scattering length where Efimov states evol…
Six-dimensional time-space crystalline structures
Giedrius Žlabys, Chu-hui Fan, Egidijus Anisimovas +1
Time crystalline structures are characterized by regularity that single-particle or many-body systems manifest in the time domain, closely resembling the spatial regularity of ordi…
Phasonic Spectroscopy of a Quantum Gas in a Quasicrystalline Lattice
Shankari V. Rajagopal, Toshihiko Shimasaki, Peter Dotti +5
Phasonic degrees of freedom are unique to quasiperiodic structures, and play a central role in poorly-understood properties of quasicrystals from excitation spectra to wavefunction…
Artificial gauge fields with ultracold atoms
Victor Galitski, Gediminas Juzeliūnas, I. B. Spielman
Gauge fields are ubiquitous in nature. In the context of quantum electrodynamics, you may be most familiar with the photon, which represents the gauge field mediating electromagnet…
Spin Hall mode in a trapped thermal Rashba gas
J. Armaitis, J. Ruseckas, H. T. C. Stoof +1
We theoretically investigate a two-dimensional harmonically-trapped gas of identical atoms with Rashba spin-orbit coupling and no interatomic interactions. In analogy with the spin…
