Holographic Entanglement Renormalization of Topological Insulators
Xueda Wen, Gil Young Cho, Pedro L. S. Lopes +3
We study the real-space entanglement renormalization group flows of topological band insulators in (2+1) dimensions by using the continuum multi-scale entanglement renormalization…
Holographic duality between -d quantum anomalous Hall state and -d topological insulators
Yingfei Gu, Ching Hua Lee, Xueda Wen +3
In this paper, we study -dimensional quantum anomalous Hall states, i.e. band insulators with quantized Hall conductance, using the exact holographic mapping. The exact holo…
Edge theory approach to topological entanglement entropy, mutual information and entanglement negativity in Chern-Simons theories
Xueda Wen, Shunji Matsuura, Shinsei Ryu
We develop an approach based on edge theories to calculate the entanglement entropy and related quantities in (2+1)-dimensional topologically ordered phases. Our approach is comple…
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…
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 dynamics of a superconducting phase qubit coupled to a two-level system
Guozhu Sun, Zhongyuan Zhou, Bo Mao +3
We report the observation and quantitative characterization of driven and spontaneous oscillations of quantum entanglement, as measured by concurrence, in a bipartite system consis…
