Enhancing Nonreciprocity through Squeezing-Induced Symmetry Breaking
B. -B. Liu, D. -Y. Wang, J. Tang +4
Reservoir engineering enables unidirectional energy and signal flow. We establish squeezing-induced symmetry breaking between two cavities as a guiding principle for exponentially…
Two-Polariton Blockade via Ultrastrong Light-Matter Coupling
Ting-Ting Ma, Jian Tang, Yun-Lan Zuo +3
We demonstrate that a two-polariton blockade (2PB) can occur under resonant single-polariton driving in an atom-cavity system operating in the ultrastrong coupling (USC) regime-a p…
Robust photon blockade with hybrid molecular optomechanics
Jian Tang, Baijun Li, Bin Yin +4
Molecular cavity optomechanical systems, featuring ultrahigh vibrational frequencies and strong light-matter interactions, hold significant promise for advancing applications in qu…
Disorder-Induced Strongly Correlated Photons in Waveguide QED
Guoqing Tian, Li-Li Zheng, Zhi-Ming Zhan +2
Strongly correlated photons play a crucial role in modern quantum technologies. Here, we investigate the probability of generating strongly correlated photons in a chain of N qubit…
Observation of multiple time crystals in a driven-dissipative system with Rydberg gas
Yuechun Jiao, Weilun Jiang, Yu Zhang +5
Time crystals, as temporal analogs of space crystals, manifest as stable and periodic behavior that breaks time translation symmetry. In an open quantum system, many-body interacti…
Dynamically encircling an exceptional point through phase-tracked closed-loop control
Sen Zhang, Yangyu Huang, Lei Yu +7
The intricate complex eigenvalues of non-Hermitian Hamiltonians manifest as Riemann surfaces in control parameter spaces. At the exceptional points (EPs), the degeneracy of both ei…
