The wave nature of a Mott insulator
Xudong Yu, Chengyang Wu, Wenhan Chen +10
Quantum phases of matter are routinely identified by coherence features, with interference patterns being one of the most directly observable quantities. In lattices, the superflui…
Entropy transport through a superfluid quantum point contact: A Keldysh field-theory approach
Davide Bertolusso, C. J. Bolech, Thierry Giamarchi
We study the matter and entropy transport between two ultra-cold neutral Fermi-gas reservoirs linked by a quantum point contact under a chemical-potential gradient. We describe the…
Solvable Random Unitary Dynamics in a Disordered Tomonaga-Luttinger Liquid
Tian-Gang Zhou, Thierry Giamarchi
Disordered one-dimensional interacting systems have long been characterized via conventional correlation functions. A complementary quantum-information perspective quantifies the r…
Tomonaga-Luttinger liquid theory for one-dimensional attractive Fermi gases
Hai-Ying Cui, Yu-Hao Yeh, Randall G. Hulet +3
The one-dimensional (1D) Yang-Gaudin model-an integrable -function interacting Fermi gas, serves as a paradigm in quantum many-body physics, encompassing phenomena from spin-ch…
Interplay of Noise and Reservoir-induced Decoherence in Persistent Currents
Samudra Sur, Thierry Giamarchi
Persistent current is a hallmark of quantum phase coherence. We study the fate of the persistent current in a non-equilibrium setting, where a tight-binding ring is subjected to st…
Spontaneous emission as a bridge from Lindbladian to nonreciprocal reservoirs
C. J. Bolech, T. Giamarchi
We study an out-of-equilibrium quantum system in which a state connecting two reservoirs is also coupled by stimulated and spontaneous emission of photons to an antitrapped state,…
