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…
Quantum-metric-nematicity induced Kerr-like polarization rotation without time-reversal symmetry breaking
Wenhao Liang, Akito Daido, K. T. Law
The magneto-optic Kerr effect (MOKE), which describes the rotation and ellipticity of linearly polarized light upon reflection, is conventionally associated with time-reversal symm…
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…
Spin Group Symmetry Criteria for Odd-parity Magnets
Xun-Jiang Luo, Jin-Xin Hu, Meng-Li Hu +1
Odd-parity magnets (OPMs) have recently emerged as a new magnetic class, but their general symmetry criteria remain elusive. In this Letter, we establish these criteria through a c…
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…
Flat band excitons and quantum metric
Xuzhe Ying, K. T. Law
We discuss the excitons in flat band systems. Quantum metric plays a central role in determining the properties of single exciton excitation as well as the exciton condensate. Whil…
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…
