# Topological thermal Hall effect for topological excitations in spin liquid: Emergent Lorentz force on the spinons

@article{Gao2019TopologicalTH, title={Topological thermal Hall effect for topological excitations in spin liquid: Emergent Lorentz force on the spinons}, author={Yong Hao Gao and Gang Chen}, journal={SciPost Physics Core}, year={2019} }

We study the origin of Lorentz force on the spinons in a U(1) spin liquid.
We are partly inspired by the previous observation of gauge field correlation in
the pairwise spin correlation using the neutron scattering measurement by
P.A. Lee an N. Nagaosa [PhysRevB 87,064423(2013)] when
the Dzyaloshinskii-Moriya interaction intertwines with the lattice geometry.
We extend this observation to the Lorentz force that exerts
on the (neutral) spinons. The external magnetic field, that polarizes…

It is shown that the exchange of energy between the two subsystems leads to a transverse component of the bulk current and thereby an effective Hall conductivity and the quality of the quantization depends on the means of measuring the temperature and, surprisingly, a more robust quantization is obtained when the lattice, not the spin, temperature is measured.
