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…
In situ magnetic-field stabilization for quantum-gas experiments
E. Gvozdiovas, A. Valdés-Curiel, Q. -Y. Liang +6
We demonstrate a minimally-destructive in situ technique for measuring and stabilizing slowly-drifting magnetic fields in ultracold-atom experiments. While conventional magnetic-fi…
Imaginary gauge potentials in a non-Hermitian spin-orbit coupled quantum gas
Junheng Tao, Emmanuel Mercado-Gutierrez, Mingshu Zhao +1
In 1996, Hatano and Nelson proposed a non-Hermitian lattice model containing an imaginary Peierls phase [Phys. Rev. Lett. 77 570-573 (1996)], which subsequent analyses revealed to…
Isothermal compressibility determination across Bose-Einstein condensation
F. J. Poveda-Cuevas, P. C. M. Castilho, E. D. Mercado-Gutierrez +5
We apply the global thermodynamic variables approach to experimentally determine the isothermal compressibility parameter of a trapped Bose gas across the phase transition. W…
Thermal Global Expansion Coefficient Measurement for a Harmonic Trapped Gas Across Bose-Einstein Condensation
E. D. Mercado-Gutierrez, F. J. Poveda-Cuevas, Vanderlei S. Bagnato
We report the measurement of the global thermal expansion coefficient of a confined Bose gas of in a harmonic potential around the Bose-Einstein condensation transiti…
