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…

Comparative analysis of specific heat of YNi2B2C using nodal and two-gap models
C. L. Huang, J. Y. Lin, C. P. Sun +5
The magnetic field dependence of low temperature specific heat in YNi2B2C was measured and analyzed using various pairing order parameters. At zero magnetic field, the two-gap mode…
