Real-Space Interference from Quantum Metric
Bo-Qing Wu, Xing-Lei Ma, Jin-Xin Hu +2
Real-space interference of wave packets is governed by their central momentum separation and momentum width, which set the oscillation wavelength and spatial envelope, respectively…
Quantum Geometric Friedel Oscillations
Xing-Lei Ma, Jinchao Zhao, Bo-Qing Wu +2
In conventional Friedel oscillations, the real-space charge density oscillations induced by an impurity are characterized by an oscillation period set by the Fermi momentum. In thi…
Tunable quantum metric and band topology in bilayer Dirac models
Xun-Jiang Luo, Xing-Lei Ma, K. T. Law
Quantum metric, a fundamental component of quantum geometry, has attracted broad interest in recent years due to its critical role in various quantum phenomena. Meanwhile, band top…
Non-Abelian Quantum Metric Governed Topological Boundary-Mode Localization
Xing-Lei Ma, Jin-Xin Hu, K. T. Law
The presence of localized boundary modes is an unambiguous hallmark of topological quantum matter. While these modes are typically protected by topological invariants such as the C…
Majorana Zero Modes in the Lieb-Kitaev Model with Tunable Quantum Metric
Xingyao Guo, Xinglei Ma, Xuzhe Ying +1
The relation between band topology and Majorana zero energy modes (MZMs) in topological superconductors had been well studied in the past decades. However, the relation between the…
