Resonant enhancement of three-body loss between strongly interacting photons
Marcin Kalinowski, Yidan Wang, Przemyslaw Bienias +7
Rydberg polaritons provide an example of a rare type of system where three-body interactions can be as strong or even stronger than two-body interactions. The three-body interactio…
Realization of a stroboscopic optical lattice for cold atoms with subwavelength spacing
T-C. Tsui, Y. Wang, S. Subhankar +2
Optical lattices are typically created via the ac-Stark shift, which are limited by diffraction to periodicities , where is the wavelength of light used to create them.…
Floquet engineering of optical lattices with spatial features and periodicity below the diffraction limit
S. Subhankar, P. Bienias, P. Titum +5
Floquet engineering or coherent time periodic driving of quantum systems has been successfully used to synthesize Hamiltonians with novel properties. In ultracold atomic systems, t…
A Wavefunction Microscope for Ultracold Atoms
Sarthak Subhankar, Yang Wang, Tsz-Chun Tsui +2
Quantum simulations with ultracold atoms typically create atomic wavefunctions with structures at optical length scales, where direct imaging suffers from the diffraction limit. In…
Griffiths Physics in an Ultracold Bose Gas
M. E. W. Reed, Z. S. Smith, Aftaab Dewan +1
Coupled XY model systems consisting of three-dimensional (3D) systems with disordered interlayer physics are of significant theoretical interest. We realize a set of coupled quasi-…
Dark state optical lattice with sub-wavelength spatial structure
Yang Wang, Sarthak Subhankar, Przemyslaw Bienias +7
We report on the experimental realization of a conservative optical lattice for cold atoms with sub-wavelength spatial structure. The potential is based on the nonlinear optical re…
