Framing Anomaly in Lattice Chern-Simons-Maxwell Theory
Ze-An Xu, Jing-Yuan Chen
Framing anomaly is a key property of chiral topological orders, for it reveals that the chirality is an intrinsic bulk property of the system, rather than a property of th…
A Discrete Formulation of Second Stiefel-Whitney Class for Band Theory
Ken Shiozaki, Jing-Yuan Chen
Topological invariants in band theory are often formulated assuming that Bloch wave functions are smoothly defined over the Brillouin zone (BZ). However, first-principles band calc…
An Explicit Categorical Construction of Instanton Density in Lattice Yang-Mills Theory
Peng Zhang, Jing-Yuan Chen
Since the inception of lattice QCD, a natural definition for the Yang-Mills instanton on lattice has been long sought for. In a recent work, one of authors showed the natural solut…
Lattice Chern-Simons-Maxwell Theory and its Chirality
Ze-An Xu, Jing-Yuan Chen
We define and solve the Chern-Simons-Maxwell theory on spacetime lattice, with an emphasis on the chirality of the theory. Realizing Chern-Simons theory on lattice ha…
Instanton Density Operator in Lattice QCD from Higher Category Theory
Jing-Yuan Chen
A natural definition for instanton density operator in lattice QCD has long been desired. We show this problem is, and has to be, solved by higher category theory. The problem is s…
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…

Xiao-Qi Sun, Jing-Yuan Chen, Steven A. Kivelson
Recent experimental observations of unexpectedly large thermal Hall conductivities, , in insulating materials, including the parent compounds of the high temperature supercond…
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…
Doubling Theorem and Boundary States of Five-Dimensional Weyl Semimetal
Jing-Yuan Chen, Biao Lian, Shou-Cheng Zhang
We study the generic band structures of the five-dimensional (5D) Weyl semimetal, in which the band degeneracies are 2D Weyl surfaces in the momentum space, and may have non-trivia…
Duality Web on a 3D Euclidean Lattice and Manifestation of Hidden Symmetries
Jun Ho Son, Jing-Yuan Chen, S. Raghu
We generalize our previous lattice construction of the abelian bosonization duality in dimensions to the entire web of dualities as well as the self-duality, via the…
Strong-Weak Chern-Simons-Matter Dualities from a Lattice Construction
Jing-Yuan Chen, Max Zimet
We provide a lattice demonstration of -dimensional field theory dualities relating free Dirac or Majorana fermions to strongly-interacting bosonic Chern-Simons-matter theori…
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 Phase Physics in Free and Interacting Fermionic Systems
Jing-Yuan Chen
Berry phase plays an important role in many non-trivial phenomena over a broad range of many-body systems. In this thesis we focus on the Berry phase due to the change of the parti…
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…
Collisions in Chiral Kinetic Theory
Jing-Yuan Chen, Dam T. Son, Mikhail A. Stephanov
Using a covariant formalism, we construct a chiral kinetic theory Lorentz invariant to order which includes collisions. We find a new contribution to the partic…
Lorentz Invariance in Chiral Kinetic Theory
Jing-Yuan Chen, Dam T. Son, Mikhail A. Stephanov +2
We show that Lorentz invariance is realized nontrivially in the classical action of a massless spin- particle with definite helicity. We find that the ordinary Lorentz tra…
The Fermionic Dark Matter Higgs Portal: an effective field theory approach
Michael A. Fedderke, Jing-Yuan Chen, Edward W. Kolb +1
We consider fermionic (Dirac or Majorana) cold thermal relic dark-matter coupling to standard-model particles through the effective dimension-5 Higgs portal operators $Λ^{-1} \ \ma…
Dark matter coupling to electroweak gauge and Higgs bosons: an effective field theory approach
Jing-Yuan Chen, Edward W. Kolb, Lian-Tao Wang
If dark matter is a new species of particle produced in the early universe as a cold thermal relic (a weakly-interacting massive particle-WIMP), its present abundance, its scatteri…
