Shedding Light on Microscopic Details: 2D Spectroscopy of 1D Quantum Ising Magnets
GiBaik Sim, Frank Pollmann, Johannes Knolle
The identification of microscopic models describing the low-energy properties of correlated materials has been a central goal of spectroscopic measurements. We demonstrate how 2D n…
Kekule spin-orbit dimer phase and triplon dynamics
GiBaik Sim
We derive and study a spin-orbital model for ions with electronic configuration on a honeycomb lattice. In this system, the directional character of orbital leads to…
Nonlinear spectroscopy of bound states in perturbed Ising spin chains
GiBaik Sim, Johannes Knolle, Frank Pollmann
We study the nonlinear response of non-integrable 1D spin models using infinite matrix-product state techniques. As a benchmark and demonstration of the method, we first calculate…
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…
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…
Triplet-Superconductivity in Triple-Band Crossings
GiBaik Sim, Moon Jip Park, SungBin Lee
Multi-band superconductivity in topological semimetals are the paradigms of unconventional superconductors. Their exotic gap structures and topological properties have fascinated s…
Topological d+s wave superconductors in a multi-orbital quadratic band touching system
GiBaik Sim, Archana Mishra, Moon Jip Park +3
Realization of topological superconductors is one of the most important goals in studies of topological phases in quantum materials. In this work, we theoretically propose a novel…
Discovery of new magnetic orders on pyrochlore spinels
GiBaik Sim, SungBin Lee
Frustration in spin system can give rise to unique ordered states and as a consequence several physical phenomena are expected such as multiferroics, high temperature superconducto…
