Isotope Effects and the Negative Thermal Expansion Phenomena in Ice and Water
B. I. Min, J. -S. Kang
H2O is a unique substance with exceptional thermal properties arising from the subtle interplay between its electronic, phononic, and structural degrees of freedom. Of particular i…
Magnetic field-induced type-II Weylsemimetallic state in geometrically frustrated Shastry-Sutherland lattice GdB4
Wonhyuk Shon, Dong-Choon Ryu, Kyoo Kim +6
Weyl semimetal is a topologically non-trivial phase of matter with pairs of Weyl nodes in the k-space, which act as monopole and anti-monopole pairs of Berry curvature. Two hallmar…
Multiple topological Dirac cones in a mixed-valent Kondo semimetal: g-SmS
Chang-Jong Kang, Dong-Choon Ryu, Junwon Kim +5
We demonstrate theoretically that the golden phase of SmS (-SmS), a correlated mixed-valent system, exhibits nontrivial surface states with diverse topology. It turns out that t…
Topological Phase Transition in an Archetypal f-electron Correlated System: Ce
Junwon Kim, Dongchoon Ryu, Chang-Jong Kang +4
A typical f-electron Kondo lattice system Ce exhibits the well-known isostructural transition, the so-called gamma-alpha transition, accompanied by an enormous volume collapse. Mos…
Experimental Realization of Type-II Dirac Fermions in PdTe Superconductor
Han-Jin Noh, Jinwon Jeong, En-Jin Cho +3
A Dirac fermion in a topological Dirac semimetal is a quadruple-degenerate quasi-particle state with a relativistic linear dispersion. Breaking either time-reversal or inversion sy…
Magnetic effects in sulfur-decorated graphene
Choongyu Hwang, Shane A. Cybart, S. J. Shin +13
The interaction between two different materials can present novel phenomena that are quite different from the physical properties observed when each material stands alone. Strong e…
