Eigenstate switching of topologically ordered states using non-Hermitian perturbations
Cheol Hun Yeom, Beom Hyun Kim, Moon Jip Park
Topologically ordered phases have robust degenerate ground states against the local perturbations, providing a promising platform for fault-tolerant quantum computation. Despite of…
Topological Domain-Wall States Hosting Quantized Polarization and Majorana Zero Modes Without Bulk Boundary Correspondence
Sang-Hoon Han, Myungjun Kang, Moon Jip Park +1
Bulk-boundary correspondence is a concept for topological insulators and superconductors that determines the existence of topological boundary states within the tenfold classificat…
Collective non-Hermitian skin effect: Point-gap topology and the doublon-holon excitations in non-reciprocal many-body systems
Beom Hyun Kim, Jae-Ho Han, Moon Jip Park
Open quantum systems provide a plethora of exotic topological phases of matter that has no Hermitian counterpart. Non-Hermitian skin effect, macroscopic collapse of bulk states to…
Exceptional Classifications of Non-Hermitian Systems
Jung-Wan Ryu, Jae-Ho Han, Chang-Hwan Yi +2
Eigenstate coalescence in non-Hermitian systems is widely observed in diverse scientific domains encompassing optics and open quantum systems. Recent investigations have revealed t…
Realization of Non-Hermitian Hopf Bundle Matter
Yung Kim, Hee Chul Park, Minwook Kyung +6
Line excitations in topological phases are a subject of particular interest because their mutual linking structures encode robust topological information of matter. It has been rec…
Topological superconductivity in an ultrathin, magnetically-doped topological insulator proximity coupled to a conventional superconductor
Youngseok Kim, Timothy M. Philip, Moon Jip Park +1
As a promising candidate system to realize topological superconductivity, the system of a 3D topological insulator (TI) grown on top of the s-wave superconductor has been extensive…
