A perspective on the pathway to a scalable quantum internet using rare-earth ions
Robert M. Pettit, Farhang Hadad Farshi, Sean E. Sullivan +2
The ultimate realization of a global quantum internet will require advances in scalable technologies capable of generating, storing, and manipulating quantum information. The essen…
Entanglement, anomalies and Mathisson's helices
Piermarco Fonda, Diego Liska, Alvaro Veliz-Osorio
We study the physical properties of a length-torsion functional which encodes the holographic entanglement entropy for 1+1 dimensional theories with chiral anomalies. Previously, w…
Spinning probes and helices in AdS
Piermarco Fonda, Diego Liska, Alvaro Veliz-Osorio
We study extremal curves associated with a functional which is linear in the curve's torsion. The functional in question is known to capture the properties of entanglement entropy…
On the Shape of Things: From holography to elastica
Piermarco Fonda, Vishnu Jejjala, Alvaro Veliz-Osorio
We explore the question of which shape a manifold is compelled to take when immersed in another one, provided it must be the extremum of some functional. We consider a family of fu…
Counting paths with Schur transitions
Pablo Diaz, Garreth Kemp, Alvaro Veliz-Osorio
In this work we explore the structure of the branching graph of the unitary group using Schur transitions. We find that these transitions suggest a new combinatorial expression for…
Scrambling without chaos in RCFT
Pawel Caputa, Tokiro Numasawa, Alvaro Veliz-Osorio
In this paper we investigate measures of chaos and entanglement in rational conformal field theories in 1+1 dimensions. First, we derive a universal formula for the late time value…
Entanglement and mutual information in two-dimensional nonrelativistic field theories
Seyed Morteza Hosseini, Alvaro Veliz-Osorio
We carry out a systematic study of entanglement entropy in nonrelativistic conformal field theories via holographic techniques. After a discussion of recent results concerning Gali…
Gravitational anomalies, entanglement entropy, and flat-space holography
Seyed Morteza Hosseini, Alvaro Veliz-Osorio
We introduce a prescription to compute the entanglement entropy of Galilean conformal field theories by combining gravitational anomalies and an İnönü-Wigner contraction. We find t…
Entanglement constant for conformal families
Pawel Caputa, Alvaro Veliz-Osorio
We show that in 1+1 dimensional conformal field theories, exciting a state with a local operator increases the Renyi entanglement entropies by a constant which is the same for ever…
Graph duality as an instrument of Gauge-String correspondence
Pablo Diaz, Hai Lin, Alvaro Veliz-Osorio
We explore an identity between two branching graphs and propose a physical meaning in the context of the gauge-gravity correspondence. From the mathematical point of view, the iden…
Free-kick condition for entanglement entropy in higher curvature gravity
Seyed Morteza Hosseini, Alvaro Veliz-Osorio
In order to compute the entanglement entropy for a given region in a theory with an Einstein gravity dual, the Ryu-Takayanagi prescription tells us that we must compute the the are…
Renormalized Entanglement Entropy for BPS Black Branes
Arpan Bhattacharyya, S. Shajidul Haque, Alvaro Veliz-Osorio
We compute the renormalized entanglement entropy (REE) for BPS black solutions in , 4d gauged supergravity. We find that this quantity decreases monotonically with the…
Attractive holographic -functions
Arpan Bhattacharyya, S. Shajidul Haque, Vishnu Jejjala +2
Using the attractor mechanism for extremal solutions in gauged supergravity, we construct a -function that interpolates between the central charges of theories at u…
Heating up branes in gauged supergravity
Kevin Goldstein, Suresh Nampuri, Álvaro Véliz-Osorio
In this note, we explore the solution space of non-extremal black objects in and gauged supergravity in the presence of fluxes. We present first order rewrit…
Quantum corrections to extremal black brane solutions
Susanne Barisch-Dick, Gabriel Lopes Cardoso, Michael Haack +1
We discuss quantum corrections to extremal black brane solutions in N=2 U(1) gauged supergravity in four dimensions. We consider modifications due to a certain class of higher-deri…
On the sigma-model of deformed special geometry
Gabriel Lopes Cardoso, Alvaro Veliz-Osorio
We discuss the deformed sigma-model that arises when considering four-dimensional N=2 abelian vector multiplets in the presence of an arbitrary chiral background field. In addition…
Non-homogenous disks in the chain of matrices
Nicolas Orantin, Alvaro Veliz-Osorio
We investigate the generating functions of multi-colored discrete disks with non-homogenous boundary conditions in the context of the Hermitian multi-matrix model where the matrice…
