On the Thermal Transport Puzzles in -RuCl
Zheng-Duo Fan, Xiao-Qi Sun, Jing-Yuan Chen
Thermal transport has been used to probe the nature of -RuCl, an important candidate of Kitaev material. Two remarkable observations were made under applied magnetic fields…
Fractional Hall Conductivity and Spin-c Structure in Solvable Lattice Hamiltonians
Zhaoyu Han, Jing-Yuan Chen
The Kapustin-Fidkowski no-go theorem forbids symmetric topological orders with non-trivial Hall conductivity in (2+1)d from admitting commuting projector Hamiltonians, where…
Solvable Lattice Hamiltonians with Fractional Hall Conductivity
Zhaoyu Han, Jing-Yuan Chen
We construct a class of lattice Hamiltonians that exhibit fractional Hall conductivity. These Hamiltonians, while not being exactly solvable, can be controllably solved in their lo…
Enhanced thermal Hall effect in nearly ferroelectric insulators
Jing-Yuan Chen, Steven A. Kivelson, Xiao-Qi Sun
In the context of recent experimental observations of an unexpectedly large thermal Hall conductivity, , in insulating (LCO) and (STO),…
Abelian Topological Order on Lattice Enriched with Electromagnetic Background
Jing-Yuan Chen
In topological phases of matter, the interplay between intrinsic topological order and global symmetry is an interesting task. In the study of topological orders with discrete glob…
Exact Boson-Fermion Duality on a 3D Euclidean Lattice
Jing-Yuan Chen, Jun Ho Son, Chao Wang +1
The idea of statistical transmutation plays a crucial role in descriptions of the fractional quantum Hall effect. However, a recently conjectured duality between a critical boson a…
Static Magnetic Response of Non-Fermi Liquid Density
Jing-Yuan Chen
We consider the response of the density of a fermion ensemble to an applied weak static magnetic field. It is known that for non-interacting Fermi gas, this response is fully chara…
Berry Fermi Liquid Theory
Jing-Yuan Chen, Dam Thanh Son
We develop an extension of the Landau Fermi liquid theory to systems of interacting fermions with non-trivial Berry curvature. We propose a kinetic equation and a constitutive rela…
