Interlocking nodal chains and their examples in carbon networks
Zhiwei Li, Yuee Xie1, Po-Yao Chang +1
Nodal chain is a typical topological phase in nodal line semimetals. Here, we propose a new topological phase -- interlocking nodal chains, in which two sets of nodal chains are in…
Orbital-enhanced Warping Effect in P\textsubscript{x},P\textsubscript{y}-derived Rashba Spin Splitting of Monatomic Bismuth Surface Alloy Surface Alloy
Guan-Yu Chen, Angus Huang, Yen-Hui Lin +6
Spin-split Rashba bands have been exploited to efficiently control the spin degree of freedom of moving electrons, which possesses a great potential in frontier applications of des…
Quantum Paracrystalline Shear Modes of the Electron Liquid
Jun Yong Khoo, Po-Yao Chang, Falko Pientka +1
Unlike classical fluids, a quantum Fermi liquid can support a long-lived and propagating shear sound wave at arbitrarily small wave vectors and frequencies, reminiscent of the tran…
Entanglement spectrum and entropy in topological non-Hermitian systems and non-unitary conformal field theories
Po-Yao Chang, Jhih-Shih You, Xueda Wen +1
We propose a method of computing and studying entanglement quantities in non-Hermitian systems by use of a biorthogonal basis. We find that the entanglement spectrum characterizes…
Evolution of entanglement spectra under generic quantum dynamics
Po-Yao Chang, Xiao Chen, Sarang Gopalakrishnan +1
We characterize the early stages of the approach to equilibrium in isolated quantum systems through the evolution of the entanglement spectrum. We find that the entanglement spectr…
Bell's Inequality and Entanglement in Qubits
Po-Yao Chang, Su-Kuan Chu, Chen-Te Ma
We propose an alternative evaluation of quantum entanglement by measuring the maximum violation of the Bell's inequality without performing a partial trace operation. This proposal…
