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…
Microcontroller based scanning transfer cavity lock for long-term laser frequency stabilization
S. Subhankar, A. Restelli, Y. Wang +2
We present a compact all-digital implementation of a scanning transfer cavity lock (STCL) for long-term laser frequency stabilization. An interrupt-driven state machine is employed…
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…
