Third quantization with Hartree approximation for open-system bosonic transport

Fernando Espinoza-Ortiz, Chih-Chun Chien

The third quantization (3rd Q) for bosons provides the exact steady-state solution of the Lindblad equation with quadratic Hamiltonians. By decomposing the interaction of the Bose…

Robustness and classical proxy of entanglement in variants of quantum walk

Christopher Mastandrea, Chih-Chun Chien

Quantum walk (QW) utilizes its internal quantum states to decide the displacement, thereby introducing single-particle entanglement between the internal and positional degrees of f…

Uhlmann quench and geometric dynamic quantum phase transition of mixed states

Jia-Chen Tang, Xu-Yang Hou, Zheng Zhou +2

Dynamic quantum phase transitions (DQPT) following quantum quenches exhibit singular behavior of the overlap between the initial and evolved states. Here we present a formalism to…

Breaking and trapping Cooper pairs by Rydberg-molecule spectroscopy in atomic Fermi superfluids

Chih-Chun Chien, Simeon I. Mistakidis, Hossein R. Sadeghpour

We propose a spectroscopic probe of the breaking and localization of Cooper pairs in an atomic Fermi superfluid interacting with a Rydberg impurity. This is achieved by monitoring…

Sjqvist quantum geometric tensor of finite-temperature mixed states

Zheng Zhou, Xu-Yang Hou, Xin Wang +3

The quantum geometric tensor (QGT) reveals local geometric properties and associated topological information of quantum states. Here a generalization of the QGT to mixed quantum st…

Interferometric Geometric Phases of -symmetric Quantum Mechanics

Xin Wang, Zheng Zhou, Jia-Chen Tang +3

We present a generalization of the geometric phase to pure and thermal states in -symmetric quantum mechanics (PTQM) based on the approach of the interferometric geom…
