Phonon transmittance of one dimensional quasicrystals
Junmo Jeon, SungBin Lee
In quasicrystals, special tiling patterns could give rise to unique physical phenomena such as critical states distinct from periodic systems. In this paper, we study how quasi-per…
Geometric Superconductivity in 3D Hofstadter Butterfly
Moon Jip Park, Yong Baek Kim, SungBin Lee
Electrons on the lattice subject to a strong magnetic field exhibit the fractal spectrum of electrons, which is known as the Hofstadter butterfly. In this work, we investigate unco…
Pressure Induced Topological Superconductivity in the Spin-Orbit Mott Insulator GaTa4Se8
Moon Jip Park, GiBaik Sim, Min Yong Jeong +3
Lacunar spinel GaTaSe is a unique example of spin-orbit coupled Mott insulator described by molecular states. It becomes superconducting at T=5…
Higher-Order Topological Instanton Tunneling Oscillation
Moon Jip Park, Sunam Jeon, SungBin Lee +2
We propose a new type of instanton interference effect in two-dimensional higher-order topological insulators. The intercorner tunneling consists of the instanton and the anti-inst…
Thermal and field-induced transitions in ferroquadrupolar Kondo systems
Frederic Freyer, SungBin Lee, Yong Baek Kim +2
Recent experiments have examined the impact of a magnetic field on ferroquadrupolar orders in the intermetallic Kondo material PrTiAl. Motivated by this, we use extensiv…
Topological critical states and anomalous electronic transmittance in one dimensional quasicrystals
Junmo Jeon, SungBin Lee
Due to the absence of periodic length scale, electronic states and their topological properties in quasicrystals have been barely understood. Here, we focus on one dimensional quas…
