Quantum transport in a non-Hermitian 1D synthetic lattice: from quantum Zeno reflection to near-perfect absorption
Emmanuel. D. Mercado-Gutiérrez, W. Xu, E. Gvozdiovas +5
We experimentally explore the absorption of a propagating wavepacket impinging upon a dissipative region in an engineered quantum system. We employ a 1D non-Hermitian synthetic lat…
Many-body phases from effective geometrical frustration and long-range interactions in a subwavelength lattice
Domantas Burba, Gediminas Juzeliūnas, Ian B. Spielman +1
Geometrical frustration and long-range couplings are key contributors to create quantum phases with different properties throughout physics. We propose a scheme where both ingredie…
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…
Direct Calibration of Laser Intensity via Ramsey Interferometry for Cold Atom Imaging
Emine Altuntas, Ian B. Spielman
A majority of ultracold atom experiments utilize resonant absorption imaging techniques to obtain the atomic density. To make well-controlled quantitative measurements, the optical…
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…
Observation of anisotropic superfluid density in an artificial crystal
Junheng Tao, Mingshu Zhao, Ian Spielman
We experimentally and theoretically investigate the anisotropic speed of sound of an atomic superfluid (SF) Bose-Einstein condensate in a 1D optical lattice. Because the speed of s…
