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…
Coherent optical nano-tweezers for ultra-cold atoms
P. Bienias, S. Subhankar, Y. Wang +8
There has been a recent surge of interest and progress in creating subwavelength free-space optical potentials for ultra-cold atoms. A key open question is whether geometric potent…
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…
