Thermal Hall Effects of Spins and Phonons in Kagome Antiferromagnet Cd-Kapellasite

Masatoshi Akazawa, Masaaki Shimozawa, Shunichiro Kittaka +7

We have investigated the thermal-transport properties of the kagome antiferromagnet Cd-kapellasite (Cd-K). We find that a field suppression effect on the longitudinal thermal condu…

Tensor network wavefunction of Kitaev spin liquids

Hyun-Yong Lee, Naoki Kawashima, Yong Baek Kim

Recently there has been a great interest in understanding quantum spin liquid phases with varying spin magnitude, partly due to possible material realizations. A number of recent n…

Magnetic field induced quantum phases in a tensor network study of Kitaev magnets

Hyun-Yong Lee, Ryui Kaneko, Li Ern Chern +4

Recent discovery of the half quantized thermal Hall conductivity in -RuCl, a candidate material for the Kitaev spin liquid, suggests the presence of a highly entangled quant…

Abelian and non-Abelian chiral spin liquids in a compact tensor network representation

Hyun-Yong Lee, Ryui Kaneko, Tsuyoshi Okubo +1

We provide new insights into the Abelian and non-Abelian chiral Kitaev spin liquids on the star lattice using the recently proposed loop gas (LG) and string gas (SG) states [H.-Y.…

Spin Thermal Hall Conductivity of a Kagomé Antiferromagnet

Hayato Doki, Masatoshi Akazawa, Hyun-Yong Lee +7

A clear thermal Hall signal () was observed in the spin liquid phase of the kagomé antiferromagnet Ca kapellasite (CaCu(OH)ClHO). We found…
