Phase Transition in a Two-level-cavity System in an Ohmic Environment
Chang-Qin Wu, Jian-Xin Li, Dung-Hai Lee
We propose that in the presence of an Ohmic, de-phasing type environment, a two-level-cavity system undergoes a quantum phase transition from a state with damped Rabi oscillation t…

Photoisomerization in a Dissipative Environment
Chang-Qin Wu, Jian-Xin Li, Dung-Hai Lee
We investigate photoisomerization (PI), the shape change of a molecule upon photoabsorption, in a dissipative environment using a simple spin-boson model. We identify two classes o…

Checkerboard charge density wave and pseudogap in high- cuprates
Jian-Xin Li, Chang-Qin Wu, Dung-Hai Lee
We consider the scenario where a 4-lattice constant, rotationally symmetric charge density wave (CDW) is present in the underdoped cuprates. We prove a theorem that puts strong con…
