Instanton effects in lattice models of bosonic symmetry-protected topological states
Luiz H. Santos, Eduardo Fradkin
Bosonic symmetry-protected topological (SPT) states are gapped disordered phases of matter possessing symmetry-preserving boundary excitations. It has been proposed that, at long w…
Unparticles and Anomalous Dimensions in the Cuprates
Andreas Karch, Kridsanaphong Limtragool, Philip W. Phillips
Motivated by the overwhelming evidence some type of quantum criticality underlies the power-law for the optical conductivity and linear resistivity in the cuprates, we demonstr…
Effective hydrodynamic field theory and condensation picture of topological insulators
AtMa P. O. Chan, Thomas Kvorning, Shinsei Ryu +1
While many features of topological band insulators are commonly discussed at the level of single-particle electron wave functions, such as the gapless Dirac spectrum at their bound…
Bulk Topological Proximity Effect
Timothy H. Hsieh, Hiroaki Ishizuka, Leon Balents +1
Existing proximity effects stem from systems with a local order parameter, such as a local magnetic moment or a local superconducting pairing amplitude. Here, we demonstrate that d…
Interplay between uni-directional and bi-directional charge-density-wave orders in underdoped cuprates
Yuxuan Wang, Andrey V. Chubukov
We analyze the interplay between charge-density-wave (CDW) orders with axial momenta and ( and respectively), detected in the underdoped cuprates. The C…
Observation of a transition from a topologically ordered to a spontaneously broken symmetry phase
N. Samkharadze, K. A. Schreiber, G. C. Gardner +3
Until the late 1980s, phases of matter were understood in terms of Landau's symmetry breaking theory. Following the discovery of the quantum Hall effect the introduction of a secon…
Bulk-boundary correspondence in (3+1)-dimensional topological phases
Xiao Chen, Apoorv Tiwari, Shinsei Ryu
We discuss (2+1)-dimensional gapless surface theories of bulk (3+1)-dimensional topological phases, such as the BF theory at level , and its generalization. In particul…
Topological Phases on Non-orientable Surfaces: Twisting by Parity Symmetry
AtMa P. O. Chan, Jeffrey C. Y. Teo, Shinsei Ryu
We discuss (2+1)D topological phases on non-orientable spatial surfaces, such as Möbius strip, real projective plane and Klein bottle, etc., which are obtained by twisting the pare…
Fluctuating charge order in the cuprates: spatial anisotropy and feedback from superconductivity
Yuxuan Wang, Debanjan Chowdhury, Andrey V. Chubukov
We analyze the form of static charge susceptibility in underdoped cuprates near axial momenta and at which short-range static charge order has been observed.…
Topological quantum field theory of three-dimensional bosonic Abelian-symmetry-protected topological phases
Peng Ye, Zheng-Cheng Gu
Symmetry-protected topological phases (SPT) are short-range entangled gapped states protected by global symmetry. Nontrivial SPT phases cannot be adiabatically connected to the tri…
Evolution of Holographic Fermi Arcs from a Mott Insulator
Garrett Vanacore, Srinidhi T. Ramamurthy, Philip W. Phillips
We study fermions in an electrically-probed and asymptotically anti-de Sitter Schwarzschild spacetime which interact via novel chiral symmetry-preserving interactions. Computing th…
Chiral spin liquids on the kagome Lattice
Krishna Kumar, Kai Sun, Eduardo Fradkin
We study the nearest neighbor Heisenberg quantum antiferromagnet on the kagome lattice. Here we consider the effects of several perturbations: a) a chirality term, b) a Dzyal…
Absence of Power-Law Mid-Infrared Conductivity in Gravitational Crystals
Brandon W. Langley, Garrett Vanacore, Philip W. Phillips
We compute conductivities of strongly-interacting and non-uniform charge densities dual to inhomogeneous anti-de Sitter--black hole spacetimes. Backreacting bulk scalars with perio…
Power-law Optical Conductivity from Unparticles: Application to the Cuprates
Kridsanaphong Limtragool, Philip Phillips
We calculate the optical conductivity using several models for unparticle or scale-invariant matter. Within a Gaussian action for unparticles that is gauged with Wilson lines, we f…
Topologically Induced Fermion Parity Flips in Superconductor Vortices
Jeffrey C. Y. Teo, Mayukh Nilay Khan, Smitha Vishveshwara
A highlighting feature of Majorana bound states in two-dimensional topological superconductors is that they gain a phase factor of upon being orbited by a vortex. This work foc…
Phase diagram of the Parafermionic Chain with Chiral Interactions
Ye Zhuang, Hitesh J. Changlani, Norm M. Tubman +1
Parafermions are exotic quasiparticles with non-Abelian fractional statistics that can be realized and stabilized in 1-dimensional models that are generalizations of the Kitaev p-w…
A discretized Chern-Simons gauge theory on arbitrary graphs
Kai Sun, Krishna Kumar, Eduardo Fradkin
In this paper, we show how to discretize the abelian Chern-Simons gauge theory on generic planar lattices/graphs (with or without translational symmetries) embedded in arbitrary 2D…
