Optical Signatures of Band Flatness and Anisotropic Quantum Geometry in Magic-Angle Twisted Bilayer Graphene
Pok Man Chiu
We study the degree of band flatness and anisotropic quantum geometry in magic-angle twisted bilayer graphene by varying the twist angle and the lattice relaxation through optical…
topological signatures of the optical bound on maximal Berry curvature: Application to two-dimensional time-reversal symmetric insulators
Pok Man Chiu
Unlike broken time-reversal symmetric (TRS) systems with a well-defined Chern number, directly measuring the bulk invariant and Berry curvature (if nonzero) in topological in…
Proximity-Effect-Induced Anisotropic Superconductivity in Monolayer Ni-Pb Binary Alloy
Yen-Hui Lin, Chia-Hsiu Hsu, Iksu Jang +7
Proximity effect facilitates the penetration of Cooper pairs that permits superconductivity in normal metal, offerring a promising approach to turn heterogeneous materials into sup…
Disorder-induced topology in quench dynamics
Hsiu-Chuan Hsu, Pok-Man Chiu, Po-Yao Chang
We study the effect of strong disorder on topology and entanglement in quench dynamics. Although disorder-induced topological phases have been well studied in equilibrium, the diso…
Emergence of topological phases from the extension of two-dimensional lattice with nonsymmorphic symmetries
Pok-Man Chiu, Cheng-Yi Huang, Wan-Ju Li +1
Young and Kane have given a great insight for 2D Dirac semimetals with nontrivial topology in the presence of nonsymmorphic crystalline symmetry. Based on one of 2D nonsymmorphic s…
Interplay between antiferromagnetic order and spin polarization in ferromagnetic metal/electron-doped cuprate superconductor junctions
Pok-Man Chiu, C. S. Liu, W. C. Wu
Recently we proposed a theory of point-contact spectroscopy and argued that the splitting of zero-bias conductance peak (ZBCP) in electron-doped cuprate superconductor point-contac…
