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…
The role of Coulomb correlation in charge density wave of CuTe
Sooran Kim, Bongjae Kim, Kyoo Kim
A quasi one-dimensional layered material, CuTe undergoes a charge density wave (CDW) transition in Te chains with a modulation vector of . Despite the clea…
