Quantum-Geometric Length Scale for Long-distance Squeezing in Bosonic Bogoliubov Systems
Sonu Verma, Sangmo Cheon, Myung-Joong Hwang +1
Multimode squeezing is a key resource for continuous-variable quantum technologies, but its spatial range in bosonic lattices is usually tied to dispersive propagation. Here we sho…
Multicritical dissipative phase transitions in the anisotropic open quantum Rabi model
Guitao Lyu, Korbinian Kottmann, Martin B. Plenio +1
We investigate the nonequilibrium steady state of the anisotropic open quantum Rabi model, which exhibits first-order and second-order dissipative phase transitions upon varying th…
Topological magnon-photon interaction for cavity magnonics
Jongjun M. Lee, Myung-Joong Hwang, Hyun-Woo Lee
The study of cavity magnonics and topological insulators has made significant advances over the past decade, however the possibility of combining the two fields is still unexplored…
Cavity magnonics with easy-axis ferromagnet: Critically enhanced magnon squeezing and light-matter interaction
Jongjun M. Lee, Hyun-Woo Lee, Myung-Joong Hwang
Generating and probing the magnon squeezing is an important challenge in the field of quantum magnonics. In this work, we propose a cavity magnonics setup with an easy-axis ferroma…
Dynamical scaling laws in the quantum -state clock chain
Jia-Chen Tang, Wen-Long You, Myung-Joong Hwang +1
We show that phase transitions in the quantum -state clock model for can be characterized by an enhanced decay behavior of the Loschmidt echo via a small quench. The…
Anomalous criticality with bounded fluctuations and long-range frustration induced by broken time-reversal symmetry
Jinchen Zhao, Myung-Joong Hwang
We consider a one-dimensional Dicke lattice with complex photon hopping amplitudes and investigate the influence of time-reversal symmetry breaking due to synthetic magnetic fields…
