Gapped Interfaces in Fracton Models and Foliated Fields
Po-Shen Hsin, Zhu-Xi Luo, Ananth Malladi
This work investigates the gapped interfaces of 3+1d fracton phases of matter using foliated gauge theories and lattice models. We analyze the gapped boundaries and gapped interfac…
Mott insulators in moiré transition metal dichalcogenides at fractional fillings: Slave-rotor mean-field theory
Zhenhao Song, Urban F. P. Seifert, Zhu-Xi Luo +1
In this work, we study a slave-rotor mean-field theory of an extended Hubbard model, applicable to transition metal dichalcogenide moiré systems, that captures both the formation o…
A model of -wave superconductivity, antiferromagnetism, and charge order on the square lattice
Maine Christos, Zhu-Xi Luo, Henry Shackleton +3
Early studies proposed a connection between cuprate superconductivity and fractionalized spin liquid states. But the low temperature phase diagram is dominated by states without fr…
Gapped boundaries of (3+1)d topological orders
Zhu-Xi Luo
Given a gapped boundary of a (3+1)d topological order (TO), one can stack on it a decoupled (2+1)d TO to get another boundary theory. Should one view these two boundaries as "diffe…
Monitored Quantum Dynamics and the Kitaev Spin Liquid
Ali Lavasani, Zhu-Xi Luo, Sagar Vijay
Quantum circuit dynamics with local projective measurements can realize a rich spectrum of entangled states of quantum matter. Motivated by the physics of the Kitaev quantum spin l…
Boundary theory of the X-cube model in the continuum
Zhu-Xi Luo, Ryan C. Spieler, Hao-Yu Sun +1
We study the boundary theory of the X-cube model using a continuum perspective, from which the exchange statistics of a subset of bulk excitations can be recovered.…
Twisted bilayer U(1) Dirac spin liquids
Zhu-Xi Luo, Urban F. P. Seifert, Leon Balents
When two layers of two-dimensional materials are assembled with a relative twist, moiré patterns arise, inducing a tremendous wealth of exotic phenomena. In this work, we consider…
A construction of exotic metallic states
Xiao-Chuan Wu, Yichen Xu, Mengxing Ye +2
We discuss examples of two dimensional metallic states with charge fractionalization, and we will demonstrate that the mechanism of charge fractionalization leads to exotic metalli…
Universal relations for holographic interfaces
Andreas Karch, Zhu-Xi Luo, Hao-Yu Sun
We study the entanglement entropy in 1+1 dimensional conformal field theories in the presence of interfaces from a holographic perspective. Compared with the well-known case of bou…
Metal-Insulator Transition with Charge Fractionalization
Yichen Xu, Xiao-Chuan Wu, Mengxing Ye +3
It has been proposed that an extended version of the Hubbard model which potentially hosts rich correlated physics may be well simulated by the transition metal dichalcogenide (TMD…
Magic continuum in twisted bilayer square lattice with staggered flux
Zhu-Xi Luo, Cenke Xu, Chao-Ming Jian
We derive the general continuum model for a bilayer system of staggered-flux square lattices, with arbitrary elastic deformation in each layer. Applying this general continuum mode…
Holographic duality for Ising CFT with boundary
Andreas Karch, Zhu-Xi Luo, Hao-Yu Sun
We extend the holographic duality between 3d pure gravity and the 2d Ising CFT proposed in [Phys. Rev. D 85 (2012) 024032] to CFTs with boundaries. Besides the usual asymptotic bou…
Heterobilayer moiré magnets: moiré skyrmions and the commensurate-incommensurate transition
Kasra Hejazi, Zhu-Xi Luo, Leon Balents
We study untwisted heterobilayers of ferromagnetic and antiferromagnetic van der Waals materials, with in particular a Dzyaloshinskii-Moriya interaction in the ferromagnetic layer.…

Kasra Hejazi, Zhu-Xi Luo, Leon Balents
We introduce a general framework to study moiré structures of two-dimensional Van der Waals magnets using continuum field theory. The formalism eliminates quasiperiodicity and allo…

We study 3D pure Einstein quantum gravity with negative cosmological constant, in the regime where the AdS radius is of the order of the Planck scale. Specifically, when the Br…

In this paper, we use the replica approach to study the Rényi entropy of generic locally excited states in (1+1)D CFTs, which are constructed from the insertion of multiple p…
Scalar Quintuplet Minimal Dark Matter with Yukawa Interactions: Perturbative up to the Planck Scale
Chengfeng Cai, Zhaofeng Kang, Zhu Luo +2
We confront the perturbativity problem in the real scalar quintuplet minimal dark matter model. In the original model, the quintuplet quartic self-coupling inevitably hits a Landau…
