Partial Kondo Screening and Anomalous Thermal Conductance
Hee Seung Kim, Hyeok-Jun Yang, SungBin Lee
The frustrated magnetism on the Kondo lattice system motivates intriguing Kondo-breakdown beyond the traditional Doniach scenario. Among them, the fractionalized Fermi liquid (FL*)…
Pattern-dependent proximity effect and Majorana edge mode in one-dimensional quasicrystals
Junmo Jeon, SungBin Lee
The Majorana edge states of the Kitaev chain model have attracted extensive attention on their stability and experimental realization. One of the interesting aspects is finding the…
Length scale formation in the Landau levels of quasicrystals
Junmo Jeon, Moon Jip Park, SungBin Lee
Exotic tiling patterns of quasicrystals have motivated extensive studies of quantum phenomena such as critical states and phasons. Nevertheless, the systematic understanding of the…
Hidden phases born of a quantum spin liquid: Application to pyrochlore spin ice
Hyeok-Jun Yang, Nic Shannon, SungBin Lee
Quantum spin liquids (QSL) have generated considerable excitement as phases of matter with emergent gauge structures and fractionalized excitations. In this context, phase transiti…
Hinge Magnons from Non-collinear Magnetic Order in Honeycomb Antiferromagnet
Moon Jip Park, SungBin Lee, Yong Baek Kim
We propose that non-collinear magnetic order in quantum magnets can harbor a novel higher-order topological magnon phase with non-Hermitian topology and hinge magnon modes. We cons…
