S-wave pairing in a two-orbital t-J model on triangular lattice: possible application to Pb $_{10 - x}$ Cu $_{x}$ (PO $_{4}$ ) $_{6}$ O

Hanbit Oh, Ya-Hui Zhang

Recently room temperature superconductor was claimed in Pb $_{10 - x}$ Cu $_{x}$ (PO $_{4}$ ) $_{6}$ O (also known as LK-99) with $x \in (0.9, 1.1)$ . Density functional theory (DFT) calculations sug…

Type II t-J model and shared antiferromagnetic spin coupling from Hund's rule in superconducting La $_{3}$ Ni $_{2}$ O $_{7}$

Hanbit Oh, Ya-Hui Zhang

Recently, a 80 K superconductor was discovered in La $_{3}$ Ni $_{2}$ O $_{7}$ under high pressure. Density function theory (DFT) calculations identify $d_{x^{2} - y^{2}}$ , $d_{z^{2}}$ as the active…

Monolayer Kagome Metals AV $_{3}$ Sb $_{5}$

Sun-Woo Kim, Hanbit Oh, Eun-Gook Moon +1

Recently, layered kagome metals AV $_{3}$ Sb $_{5}$ (A = K, Rb, and Cs) have emerged as a fertile platform for exploring frustrated geometry, correlations, and topology. Here, using first…

Exotic Thermal Transitions with Spontaneous Symmetry Breaking

Hanbit Oh, Eun-Gook Moon

We show that exotic spontaneous symmetry breaking appears in thermal topological phases by perturbing the exact solutions of quantum rotor models coupled to the three-dimensional t…

Using Disorder to Identify Bogoliubov Fermi-Surface States

Hanbit Oh, Daniel F. Agterberg, Eun-Gook Moon

We argue that a superconducting state with a Fermi-surface of Bogoliubov quasiparticles, a Bogoliubov Fermi-surface (BG-FS), can be identified by the dependence of physical quantit…

Proximity-induced hidden order transition in a correlated heterostructure Sr $_{2}$ VO $_{3}$ FeAs

Sunghun Kim, Jong Mok Ok, Hanbit Oh +10

Symmetry is one of the most significant concepts in physics, and its importance has been largely manifested in phase transitions by its spontaneous breaking. In strongly correlated…

Instability of $j = 3/2$ Bogoliubov Fermi-surfaces

Hanbit Oh, Eun-Gook Moon

Exotic quantum phases including topological states and non-Fermi liquids may be realized by quantum states with total angular momentum $j = 3/2$ , as manifested in HgTe and pyrochlore…

Multi-scale Quantum Criticality driven by Kondo-lattice Coupling in Pyrochlore Systems

Hanbit Oh, Sangjin Lee, Yong Baek Kim +1

Pyrochlore systems ( $A_{2} B_{2} O_{7}$ ) with $A$ -site rare-earth local moments and $B$ -site $5 d$ conduction electrons offer excellent material platforms for the discovery of exotic…
