Monolayer van der Waals kagome lattice for high-temperature flat-band physics
Hyungkun Bong, Choongjae Won, Seongyong Lee +26
Kagome lattice materials host a remarkably rich landscape of novel quantum phenomena, all arising from the intrinsic interplay of topology, correlation, and frustration. While prev…
Sizable suppression of magnon Hall effect by magnon damping in CrGeTe
Ysun Choi, Heejun Yang, Jaena Park +1
Two-dimensional (2D) Heisenberg honeycomb ferromagnets are expected to have interesting topological magnon effects as their magnon dispersion can have Dirac points. The Dirac point…
Significant thermal Hall effect in the 3 cobalt Kitaev system
Heejun Yang, Chaebin Kim, Ysun Choi +9
Kitaev physics has recently attracted attention in condensed matter for its anticipated novel quantum spin liquid state. The thermal transport measurement is crucial for probing th…
Sizeable suppression of thermal Hall effect upon isotopic substitution in strontium titanate
Sangwoo Sim, Heejun Yang, Ha-Leem Kim +4
We report measurements of the thermal Hall effect in single crystals of both pristine and isotopically substituted strontium titanate. We discovered a two orders of magnitude diffe…
