Scaling behavior of eigenspectrum for entanglement from correlation matrices
Lih-King Lim
We study the scaling behavior of the eigenvalues of correlation matrices, which characterize the entanglement of a subsystem with its complement part of a total pure state. A most…
Dynamical Geometry of the Haldane Model under a Quantum Quench
Liwei Qiu, Lih-King Lim, Xin Wan
We explore the time evolution of a topological system when the system undergoes a sudden quantum quench within the same nontrivial phase. Using Haldane's honeycomb model as an exam…
Mesoscopic fluctuations in entanglement dynamics
Lih-King Lim, Cunzhong Lou, Chushun Tian
Understanding fluctuation phenomena plays a dominant role in the development of many-body physics. The time evolution of entanglement is essential to a broad range of subjects in m…
Dirac points emerging from flat bands in Lieb-kagomé lattices
Lih-King Lim, Jean-Noël Fuchs, Frédéric Piéchon +1
The energy spectra for the tight-binding models on the Lieb and kagomé lattices both exhibit a flat band. We present a model which continuously interpolates between these two limit…
Winding vector: how to annihilate two Dirac points with the same charge
Gilles Montambaux, Lih-King Lim, Jean-Noël Fuchs +1
The merging or emergence of a pair of Dirac points may be classified according to whether the winding numbers which characterize them are opposite ( scenario) or identical ($++…
Quantum Oscillations in Nodal Line Systems
Hui Yang, Roderich Moessner, Lih-King Lim
We study signatures of magnetic quantum oscillations in three-dimensional nodal line semimetals at zero temperature. The extended nature of the degenerate bands can result in a Fer…
