Dual-species alkali and alkaline-earth-like optical tweezer arrays via interferometrically aligned high-NA objectives
K. Weber, M. McMaster, M. Anderson +7
We have developed a dual-species optical tweezer array apparatus combining and atoms with a permanent hybrid Twyman-Green--Fizeau interferometer,…
Interfacing of an optical nanofiber with tunably spaced atoms in an optical lattice
Hyok Sang Han, Ahreum Lee, Sarthak Subhankar +2
We experimentally demonstrate efficient interfacing of a large number of atoms to an optical nanofiber using an optical lattice with tunable spacing (m) projected onto…
A practical guide to feedback control for Pound-Drever-Hall laser linewidth narrowing
Wance Wang, Sarthak Subhankar, Joseph W. Britton
The Pound-Drever-Hall (PDH) technique for laser linewidth narrowing is widely used by AMO experimentalists. However, achieving a high-performance PDH locking requires substantial e…
Versatile optical accordion lattices using binary phase transmission gratings
Hyok Sang Han, Ahreum Lee, Sarthak Subhankar +2
Optical accordion lattices are routinely used in quantum simulation and quantum computation experiments to tune optical lattice spacings. Here, we present a technique for creating…
Quadrature amplitude modulation for electronic sideband Pound-Drever-Hall laser frequency locking
J. Tu, A. Restelli, K. Weber +4
The Pound--Drever--Hall (PDH) technique is routinely used to stabilize the frequency of a laser to a reference cavity. Electronic sideband (ESB) locking, a PDH variant, bridges the…
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…
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…
