Corner contribution to the entanglement entropy of an O(3) quantum critical point in 2+1 dimensions
Ann B. Kallin, E. M. Stoudenmire, Paul Fendley +2
The entanglement entropy for a quantum critical system across a boundary with a corner exhibits a sub-leading logarithmic scaling term with a scale-invariant coefficient. Using a N…
Entanglement at a Two-Dimensional Quantum Critical Point: a Numerical Linked Cluster Expansion Study
Ann B. Kallin, Katharine Hyatt, Rajiv R. P. Singh +1
We develop a method to calculate the bipartite entanglement entropy of quantum models, in the thermodynamic limit, using a Numerical Linked Cluster Expansion (NLCE) involving only…
Detecting Classical Phase Transitions with Renyi Mutual Information
Jason Iaconis, Stephen Inglis, Ann B. Kallin +1
By developing a method to represent the Renyi entropies via a replica-trick on classical statistical mechanical systems, we introduce a procedure to calculate the Renyi Mutual Info…
Entanglement scaling in two-dimensional gapless systems
Hyejin Ju, Ann B. Kallin, Paul Fendley +2
We numerically determine subleading scaling terms in the ground-state entanglement entropy of several two-dimensional (2D) gapless systems, including a Heisenberg model with Néel o…
Anomalies in the Entanglement Properties of the Square Lattice Heisenberg Model
Ann B. Kallin, Matthew B. Hastings, Roger G. Melko +1
We compute the bipartite entanglement properties of the spin-half square-lattice Heisenberg model by a variety of numerical techniques that include valence bond quantum Monte Carlo…
Finite Temperature Critical Behavior of Mutual Information
Rajiv R. P. Singh, Matthew B. Hastings, Ann B. Kallin +1
We study mutual information for Renyi entropy of arbitrary index n, in interacting quantum systems at finite-temperature critical points, using high-temperature expansion, quantum…
