Detection of small single-cycle signals by stochastic resonance using a bistable superconducting quantum interference device
Guozhu Sun, Jiquan Zhai, Xueda Wen +6
We propose and experimentally demonstrate detecting small single-cycle and few-cycle signals by using the symmetric double-well potential of a radio frequency superconducting quant…
Simulating the Kibble-Zurek mechanism of the Ising model with a superconducting qubit system
Ming Gong, Xueda Wen, Guozhu Sun +11
The Kibble-Zurek mechanism (KZM) predicts the density of topological defects produced in the dynamical processes of phase transitions in systems ranging from cosmology to condensed…
Observation of coherent oscillation in single-passage Landau-Zener transitions
Guozhu Sun, Xueda Wen, Ming Gong +6
Landau-Zener transition (LZT) has been explored in a variety of physical systems for coherent population transfer between different quantum states. In recent years, there have been…
Entanglement negativity after a local quantum quench in conformal field theories
Xueda Wen, Po-Yao Chang, Shinsei Ryu
We study the time evolution of the entanglement negativity after a local quantum quench in (1+1)-dimensional conformal field theories (CFTs), which we introduce by suddenly joining…
