Density matrix renormalization group on a cylinder in mixed real and momentum space
Johannes Motruk, Michael P. Zaletel, Roger S. K. Mong +1
We develop a variant of the density matrix renormalization group (DMRG) algorithm for two-dimensional cylinders that uses a real space representation along the cylinder and a momen…
Space group symmetry fractionalization in a chiral kagome Heisenberg antiferromagnet
Michael P. Zaletel, Zhenyue Zhu, Yuan-Ming Lu +2
The anyonic excitations of a spin-liquid can feature fractional quantum numbers under space-group symmetries. Detecting these fractional quantum numbers, which are analogs of the f…
Translational symmetry and microscopic constraints on symmetry-enriched topological phases: a view from the surface
Meng Cheng, Michael Zaletel, Maissam Barkeshli +2
The Lieb-Schultz-Mattis theorem and its higher dimensional generalizations by Oshikawa and Hastings require that translationally invariant 2D spin systems with a half-integer spin…
A Quantum Dipolar Spin Liquid
Norman Y. Yao, Michael P. Zaletel, Dan M. Stamper-Kurn +1
Quantum spin liquids are a new class of magnetic ground state in which spins are quantum mechanically entangled over macroscopic scales. Motivated by recent advances in the control…
Featureless quantum insulator on the honeycomb lattice
Panjin Kim, Hyunyong Lee, Shenghan Jiang +5
We show how to construct fully symmetric, gapped states without topological order on a honey- comb lattice for S = 1/2 spins using the language of projected entangled pair states(P…
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…
The Existence of Featureless Paramagnets on the Square and the Honeycomb Lattices in 2+1D
Chao-Ming Jian, Michael Zaletel
The peculiar features of quantum magnetism sometimes forbid the existence of gapped `featureless' paramagnets which are fully symmetric and unfractionalized. The Lieb-Schultz-Matti…
Filling-Enforced Quantum Band Insulators in Spin-Orbit Coupled Crystals
Hoi Chun Po, Haruki Watanabe, Michael P. Zaletel +1
While band insulators are usually described in wavevector space in terms of fully filled bands, they are sometimes also described in terms of a complementary Wannier picture in whi…
Filling constraints for spin-orbit coupled insulators in symmorphic and non-symmorphic crystals
Haruki Watanabe, Hoi Chun Po, Ashvin Vishwanath +1
We determine conditions on the filling of electrons in a crystalline lattice to obtain the equivalent of a band insulator -- a gapped insulator with neither symmetry breaking nor f…
Fibonacci anyons and charge density order in the 12/5 and 13/5 plateaus
Roger S. K. Mong, Michael P. Zaletel, Frank Pollmann +1
The fractional quantum Hall plateau observed in semiconductor wells is a suspect in the search for non-Abelian Fibonacci anyons. Using the infinite density…
Competing Abelian and non-Abelian topological orders in quantum Hall bilayers
Scott Geraedts, Michael P. Zaletel, Zlatko Papić +1
Bilayer quantum Hall systems, realized either in two separated wells or in the lowest two sub-bands of a wide quantum well, provide an experimentally realizable way to tune between…
Measuring space-group symmetry fractionalization in Z spin liquids
Michael Zaletel, Yuan-Ming Lu, Ashvin Vishwanath
The interplay of symmetry and topological order leads to a variety of distinct phases of matter, the Symmetry Enriched Topological (SET) phases. Here we discuss physical observable…
