The beginning of the endpoint bootstrap for conformal line defects
Ryan A. Lanzetta, Shang Liu, Max A. Metlitski
A challenge in the study of conformal field theory (CFT) is to characterize the possible defects in specific bulk CFTs. Given the success of numerical bootstrap techniques applied…
Extraordinary transition at the edge of a correlated topological insulator
Francesco Parisen Toldin, Fakher F. Assaad, Max A. Metlitski
The interplay of topology and correlations defines a new playground to study boundary criticality in quantum systems. We employ large scale auxiliary field quantum Monte Carlo simu…
The Kondo impurity in the large spin limit
Abijith Krishnan, Max A. Metlitski
The Kondo problem, which describes the interaction of a spin magnetic impurity with a free Fermi gas, is a classic example of strongly coupled physics. Historically, the proble…
A plane defect in the 3d O model
Abijith Krishnan, Max A. Metlitski
It was recently found that the classical 3d O model in the semi-infinite geometry can exhibit an "extraordinary-log" boundary universality class, where the spin-spin correlati…
Landau-Forbidden Quantum Criticality in Rydberg Quantum Simulators
Jong Yeon Lee, Joshua Ramette, Max A. Metlitski +3
The Landau-Ginzburg-Wilson theory of phase transitions precludes a continuous transition between two phases that spontaneously break distinct symmetries. However, quantum mechanica…
Magnetic impurities at quantum critical points: large- expansion and SPT connections
Shang Liu, Hassan Shapourian, Ashvin Vishwanath +1
In symmetry protected topological (SPT) phases, the combination of symmetries and a bulk gap stabilizes protected modes at surfaces or at topological defects. Understanding the fat…
Boundary criticality of the O(N) model in d = 3 critically revisited
Max A. Metlitski
It is known that the classical model in dimension at its bulk critical point admits three boundary universality classes: the ordinary, the extra-ordinary and the spe…
A 1d lattice model for the boundary of the quantum spin-Hall insulator
Max A. Metlitski
We present a 1d lattice model that mimics the boundary of the conventional 2d quantum spin-Hall insulator (QSHI) with symmetry and time-reversal , satisfying $T^2 = (-1)^…
1d lattice models for the boundary of 2d "Majorana" fermion SPTs: Kramers-Wannier duality as an exact symmetry
Robert A. Jones, Max A. Metlitski
It is well known that symmetry protected topological (SPT) phases host non-trivial boundaries that cannot be mimicked in a lower-dimensional system with a conventional realization…
Surface Topological Order and a new 't Hooft Anomaly of Interaction Enabled 3+1D Fermion SPTs
Lukasz Fidkowski, Ashvin Vishwanath, Max A. Metlitski
Symmetry protected topological (SPT) phases are well understood in the context of free fermions and in the context of interacting but essentially bosonic models. Recently it has be…
Intrinsic and emergent anomalies at deconfined critical points
Max A. Metlitski, Ryan Thorngren
It is well known that theorems of Lieb-Schultz-Mattis type prohibit the existence of a trivial symmetric gapped ground state in certain systems possessing a combination of internal…
Duality and bosonization of (2+1)d Majorana fermions
Max A. Metlitski, Ashvin Vishwanath, Cenke Xu
We construct a dual bosonized description of a massless Majorana fermion in . In contrast to Dirac fermions, for which a bosonized description can be constructed using a fl…
Realizing topological surface states in a lower-dimensional flat band
Andrew C. Potter, Chong Wang, Max A. Metlitski +1
The anomalous surface states of symmetry protected topological (SPT) phases are usually thought to be only possible in conjunction with the higher dimensional topological bulk. How…
Time reversal invariant gapped boundaries of the double semion state
Fiona Burnell, Xie Chen, Alexei Kitaev +2
The boundary of a fractionalized topological phase can be gapped by condensing a proper set of bosonic quasiparticles. Interestingly, in the presence of a global symmetry, such a b…
The half-filled Landau level: the case for Dirac composite fermions
Scott D. Geraedts, Michael P. Zaletel, Roger S. K. Mong +3
One of the most spectacular experimental findings in the fractional quantum Hall effect is evidence for an emergent Fermi surface when the electron density is nearly half the densi…
Particle-vortex duality of 2d Dirac fermion from electric-magnetic duality of 3d topological insulators
Max A. Metlitski, Ashvin Vishwanath
Particle-vortex duality is a powerful theoretical tool that has been used to study bosonic systems. Here we propose an analogous duality for Dirac fermions in 2+1 dimensions. The p…
Interaction effects on 3D topological superconductors: surface topological order from vortex condensation, the 16 fold way and fermionic Kramers doublets

Three dimensional topological superconductors with time reversal symmetry (class DIII) are indexed by an integer , the number of surface Majorana cones, according to the free fe…
Are non-Fermi-liquids stable to Cooper pairing?
Max A. Metlitski, David F. Mross, Subir Sachdev +1
States of matter with a sharp Fermi-surface but no well-defined Landau quasiparticles arise in a number of physical systems. Examples include: quantum critical points a…
A symmetry-respecting topologically-ordered surface phase of 3d electron topological insulators
Max A. Metlitski, C. L. Kane, Matthew P. A. Fisher
A 3d electron topological insulator (ETI) is a phase of matter protected by particle-number conservation and time-reversal symmetry. It was previously believed that the surface of…
Bosonic topological insulator in three dimensions and the statistical Witten effect
Max A. Metlitski, C. L. Kane, Matthew P. A. Fisher
