Deconfined Thermal Phase Transitions with Gauge Structures
Eun-Gook Moon
Fathoming deconfined phases is one of the key issues in modern condensed matter. Striking many-body effects including massive quantum entanglement and coherence may be realized as…
Multi-scale Quantum Criticality driven by Kondo-lattice Coupling in Pyrochlore Systems
Hanbit Oh, Sangjin Lee, Yong Baek Kim +1
Pyrochlore systems () with -site rare-earth local moments and -site conduction electrons offer excellent material platforms for the discovery of exotic…
Emergent Anisotropic Non-Fermi Liquid at a Topological Phase Transition in Three Dimensions
SangEun Han, Changhee Lee, Eun-Gook Moon +1
Understanding correlation effects in topological phases and their transitions is a cutting-edge area of research in recent condensed matter physics. We study topological quantum ph…
Vestiges of Topological Phase Transitions in Kitaev Quantum Spin Liquids
Ara Go, Jun Jung, Eun-Gook Moon
We investigate signatures of topological quantum phase transitions (TQPTs) between the quantum spin liquids (QSLs). In two spatial dimensions, QSLs and their TQPTs are…
Quantum Criticalities with Infinite Anisotropy in Topological Phase Transitions between Dirac and Weyl Semi-metals
SangEun Han, Gil Young Cho, Eun-Gook Moon
We study quantum phase transitions (QPTs) associated with splitting nodal Fermi points, motivated by topological phase transitions between Dirac and Weyl semi-metals. A Dirac point…
Exotic Symmetry Breaking Transitions in 2D Correlated Systems
Sangjin Lee, Jun Jung, Ara Go +1
The Landau paradigm of phase transitions is one of the backbones in critical phenomena. With a symmetry, it describes the Ising universality class whose central charge is one…
Long-range Coulomb Interaction effects on Topological Phase Transitions between Semi-metals and Insulators
SangEun Han, Eun-Gook Moon
Topological states may be protected by a lattice symmetry in a class of topological semi-metals. In three spatial dimensions, the Berry flux around gapless excitations in momentum…
Spin-lattice Coupling in U(1) Quantum Spin Liquids
Sangjin Lee, Eun-Gook Moon
Quantum spin liquids (QSLs) are exotic phases with intrinsic massive entanglements. Instead of microscopic spins, fractionalized particles and gauge fluctuations are emergent, reve…
