Gapped quantum spin liquid in a triangular-lattice Ising-type antiferromagnet PrMgAl11O19

Autor: Tu, Chengpeng, Ma, Zhen, Wang, Hanru, Jiao, Yihan, Dai, Dongzhe, Li, Shiyan

In the search of quantum spin liquid (QSLs), spin-1/2 triangular-lattice Heisenberg antiferromagnets (TLHAFs) have always been viewed as fertile soils. Despite the true magnetically-ordered ground state, anisotropy has been considered to play a signi

Discovery of universal phonon thermal Hall effect in crystals

Autor: Jin, Xiaobo, Zhang, Xu, Wan, Wenbo, Wang, Hanru, Jiao, Yihan, Li, Shiyan

Thermal Hall effect (THE) in insulator is a remarkable phenomenon that arises from the motion of chargeless quasi-particles under a magnetic field. While magnons or exotic spin excitations were considered as the origin of THE in some magnetic materia

Multigap nodeless superconductivity in the topological semimetal PdTe

Recently PdTe was identified as a spin-orbit coupled topological Dirac semimetal and was claimed to exhibit both bulk-nodal and surface-nodeless superconducting gaps. Here we report the ultralow-temperature thermal conductivity measurements on PdTe s
