Disorder-driven Phase Transitions of Second-order Non-Hermitian Skin Effects
Kyoung-Min Kim, Moon Jip Park
Non-Hermitian skin effect exhibits the collapse of the extended bulk modes into the extensive number of localized boundary states in open boundary conditions. Here we demonstrate t…
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…
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…
Multipolar superconductivity in Luttinger semimetals
GiBaik Sim, Archana Mishra, Moon Jip Park +3
Topological superconductivity in multiband systems has received much attention due to a variety of possible exotic superconducting order parameters as well as non-trivial bulk and…
