Pairing Instabilities of the Yukawa-SYK Models with Controlled Fermion Incoherence
Wonjune Choi, Omid Tavakol, Yong Baek Kim
The interplay of non-Fermi liquid and superconductivity born out of strong dynamical interactions is at the heart of the physics of unconventional superconductivity. As a solvable…
A hybrid percolation transition at a finite transition point in scale-free networks
K. Choi, Wonjun Choi, B. Kahng
Percolation transition (PT) means the formation of a macroscopic-scale large cluster, which exhibits a continuous transition. However, when the growth of large clusters is globally…
Spectroscopic fingerprints of gapped quantum spin liquids, both conventional and fractonic
Rahul M. Nandkishore, Wonjune Choi, Yong Baek Kim
We explain how gapped quantum spin liquids, both conventional and 'fractonic', may be unambiguously diagnosed experimentally using the technique of multidimensional coherent spectr…
Theory of two-dimensional nonlinear spectroscopy for the Kitaev spin liquid
Wonjune Choi, Ki Hoon Lee, Yong Baek Kim
Unambiguous identification of fractionalized excitations in quantum spin liquids has been a long-standing issue in correlated topological phases. Conventional spectroscopic probes,…
Symmetry-protected topological magnons in three dimensional Kitaev materials
Wonjune Choi, Tomonari Mizoguchi, Yong Baek Kim
Topological phases in magnetic materials offer novel tunability of topological properties via varying the underlying magnetism. We show that three dimensional Kitaev materials can…
Topological superconductivity in Kondo-Kitaev model
Wonjune Choi, Philipp W. Klein, Achim Rosch +1
We investigate possible topological superconductivity in the Kondo-Kitaev model on the honeycomb lattice, where the Kitaev spin liquid is coupled to conduction electrons via the Ko…
Classification and properties of quantum spin liquids on the hyperhoneycomb lattice
Biao Huang, Wonjune Choi, Yong Baek Kim +1
The family of "Kitaev materials" provides an ideal platform to study quantum spin liquids and their neighboring magnetic orders. Motivated by the possibility of a quantum spin liqu…
Theory of a quantum spin liquid in hydrogen-intercalated honeycomb iridate, H3LiIr2O6
Kevin Slagle, Wonjune Choi, Li Ern Chern +1
We propose a theoretical model for a gapless spin liquid phase that may have been observed in a recent experiment on . Despite the insulating and non-magne…
Two golden times in two-step contagion models
Wonjun Choi, Deokjae Lee, J. Kertész +1
The two-step contagion model is a simple toy model for understanding pandemic outbreaks that occur in the real world. The model takes into account that a susceptible person either…
Critical behavior of a two-step contagion model with multiple seeds
Wonjun Choi, Deokjae Lee, B. Kahng
A two-step contagion model with a single seed serves as a cornerstone for understanding the critical behaviors and underlying mechanism of discontinuous percolation transitions ind…
Mixed-order phase transition in a two-step contagion model with single infectious seed
Wonjun Choi, Deokjae Lee, B. Kahng
A hybrid phase transition (HPT) that exhibits properties of continuous and discontinuous phase transitions at the same transition point has been observed in diverse complex systems…
Absence of Anderson localization in certain random lattices
Wonjun Choi, Cheng Yin, Ian R. Hooper +2
We report on the transition between an Anderson localized regime and a conductive regime in a 1D scattering system with correlated disorder. We show experimentally that when long-r…
Fluctuations of red blood cell membranes: The role of cytoskeleton
Wonjune Choi, Juyeon Yi, Yong Woon Kim
We theoretically investigate the membrane fluctuations of red blood cells with focus laid on the role of the cytoskeleton, viewing the system as a membrane coupled to sparse spring…
