Experimental observation of Higgs oscillations and their power-law decay across pairing regimes in a cavity QED quantum simulator
Chitose Maruko, Haoqing Zhang, Eliot A. Bohr +6
Understanding how pairing correlations in superconductors evolve out of equilibrium is a central challenge in quantum many-body physics. In systems with -wave pairing, the chara…

A key challenge in observing measurement-induced phase transitions is the mitigation of the post-selection barrier, which causes the reproducibility of specific sequences of measur…
Many-body gap protection of motional dephasing of an optical clock transition
Zhijing Niu, Vera M. Schäfer, Haoqing Zhang +7
Quantum simulation and metrology with atoms, ions, and molecules often rely on using light fields to manipulate their internal states. The absorbed momentum from the light fields c…
Emergent interaction-induced topology in Bose-Hubbard ladders
