Strongly-Correlated Electron-Photon Systems
Jacqueline Bloch, Andrea Cavalleri, Victor Galitski +2
An important goal of modern condensed matter physics involves the search for states of matter with new emergent properties and desirable functionalities. Although the tools for mat…
On the path integral approach to quantum anomalies in interacting models
Alireza Parhizkar, Colin Rylands, Victor Galitski
The prediction and subsequent discovery of topological semimetal phases of matter in solid state systems has instigated a surge of activity investigating the exotic properties of t…
Monopole Josephson Effects in a Dirac Spin Liquid
Gautam Nambiar, Daniel Bulmash, Victor Galitski
Dirac Spin liquids (DSLs) are gapless featureless states, yet interesting by virtue of the effective field theory describing them -- (2+1)-dimensional quantum electrodynamics (QED$…
Interplay of symmetry breaking and deconfinement in 3D quantum vertex models
Shankar Balasubramanian, Daniel Bulmash, Victor Galitski +1
We construct a broad class of frustration-free quantum vertex models in 3+1D whose ground states are weighted superpositions of classical 3D vertex model configurations. Our result…
Classical vertex model dualities in a family of 2D frustrated quantum antiferromagnets
Shankar Balasubramanian, Victor Galitski, Ashvin Vishwanath
We study a general class of easy-axis spin models on a lattice of corner sharing even-sided polygons with all-to-all interactions within a plaquette. The low energy description cor…
Non-Abelian bosonization in a (3+1)-d Kondo semimetal via quantum anomalies
Colin Rylands, Alireza Parhizkar, Victor Galitski
Kondo lattice models have established themselves as an ideal platform for studying the interplay between topology and strong correlations such as in topological Kondo insulators or…
Chiral Anomaly in Interacting Condensed Matter Systems
Colin Rylands, Alireza Parhizkar, Anton A. Burkov +1
The chiral anomaly is a fundamental quantum mechanical phenomenon which is of great importance to both particle physics and condensed matter physics alike. In the context of QED it…
Spiral antiferromagnets beyond the spin-wave approximation: frustrated and Heisenberg models in the honeycomb lattice
Andrea Di Ciolo, Juan Carrasquilla, Federico Becca +2
We examine the stability of classical states with a generic incommensurate spiral order against quantum fluctuations. Specifically, we focus on the frustrated spin-1/2 and Hei…
Nature of the phases in the frustrated XY model on the honeycomb lattice
Juan Carrasquilla, Andrea Di Ciolo, Federico Becca +2
We study the phase diagram of the frustrated XY model on the honeycomb lattice by using accurate correlated wave functions and variational Monte Carlo simulations. Our results sugg…
A theory of Topological Kondo Insulators
Maxim Dzero, Kai Sun, Piers Coleman +1
We examine how the properties of the Kondo insulators change when the symmetry of the underlying crystal field multiplets is taken into account. We employ the Anderson lattice mode…
Topological Phase Transitions for Interacting Finite Systems
Christopher N. Varney, Kai Sun, Marcos Rigol +1
In this paper, we investigate signatures of topological phase transitions in interacting systems. We show that the key signature is the existence of a topologically protected level…
Interaction effects and quantum phase transitions in topological insulators
Christopher N. Varney, Kai Sun, Marcos Rigol +1
We study strong correlation effects in topological insulators via the Lanczos algorithm, which we utilize to calculate the exact many-particle ground-state wave function and its to…
