Quantum Geometry and Landau Levels of Quadratic Band Crossings
Junseo Jung, Hyeongmuk Lim, Bohm-Jung Yang
We study the relation between the quantum geometry of wave functions and the Landau level (LL) spectrum of two-band Hamiltonians with a quadratic band crossing point (QBCP) in two-…
Hidden Breathing Kagome Topology in Hexagonal Transition Metal Dichalcogenides
Jun Jung, Yong-Hyun Kim
A Kagome lattice, formed by triangles of two different directions, is known to have many emergent quantum phenomena. Under the breathing anisotropy of bond strengths, this lattice…
Wave-function geometry of band crossing points in two-dimensions
Yoonseok Hwang, Junseo Jung, Jun-Won Rhim +1
Geometry of the wave function is a central pillar of modern solid state physics. In this work, we unveil the wave-function geometry of two-dimensional semimetals with band crossing…
Vestiges of Topological Phase Transitions in Kitaev Quantum Spin Liquids
Ara Go, Jun Jung, Eun-Gook Moon
We investigate signatures of topological quantum phase transitions (TQPTs) between the quantum spin liquids (QSLs). In two spatial dimensions, QSLs and their TQPTs are…
Exotic Symmetry Breaking Transitions in 2D Correlated Systems
Sangjin Lee, Jun Jung, Ara Go +1
The Landau paradigm of phase transitions is one of the backbones in critical phenomena. With a symmetry, it describes the Ising universality class whose central charge is one…
