Optical Signatures and Quantum Geometry in Proximity-Induced Topological Superconductors
Myungjun Kang, Yogeshwar Prasad, Nikhil Danny Babu +3
Topological-insulator-superconductor (TI-SC) heterostructures provide a promising platform for proximity-induced topological superconductivity, but diagnosing superconductivity at…
Higher-Order Topological Systems and Their Sub-Symmetry-Protected Topology
Myungjun Kang, Wonjun Sung, Sonu Verma +1
Symmetry and topology are essential principles in topological physics. Recently, the idea of sub-symmetry-protected topology -- where some of the original symmetries are broken whi…
Sub-symmetry Protected Topology in Topological Insulators and Superconductors
Myungjun Kang, Mingyu Lee, Sangmo Cheon
Exploration of topology protected by a certain symmetry is central in condensed matter physics. A recent idea of sub-symmetry-protected (SSP) topology--remains of a broken symmetry…
Evidence of surface -wave superconductivity and higher-order topology in MoTe
Sangyun Lee, Myungjun Kang, Duk Y. Kim +4
Exploration of nontrivial superconductivity and electronic band topology is at the core of condensed matter physics and applications to quantum information. The transition-metal di…
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…
Collision, mechanism, and operation among chiral and nonchiral kinks in coupled double-field model
Jin-Hyung Choi, Sang-Hoon Han, Myungjun Kang +1
In this work, we investigate collision processes and their mechanism among chiral and nonchiral kinks in the coupled double-field model and show that the kink collisions foll…
Low-energy electrodynamics of Dirac semimetal phases in the doped Mott insulator SrIrO
Sun-Woo Kim, Myungjun Kang, Sangmo Cheon
Correlated Dirac semimetal phases emerge in lightly doped (Tb- or La-doped) Mott insulator SrIrO, where a d-wave symmetry-breaking order underlying a pseudogap plays a cruc…
"Photonic" cat states from strongly interacting matter waves
Uwe R. Fischer, Myung-Kyun Kang
We consider ultracold quantum gases of scalar bosons, residing in a coupling strength--density regime in which they constitute a twofold fragmented condensate trapped in a single w…
Revealing single-trap condensate fragmentation by measuring density-density correlations after time of flight
Myung-Kyun Kang, Uwe R. Fischer
We consider ultracold bosonic atoms in a single trap in the Thomas-Fermi regime, forming many-body states corresponding to stable macroscopically fragmented two-mode condensates. I…
