Holography of dilatonic black holes
Mariano Cadoni - University of Cagliari
We discuss bulk and holographic features of black hole solutions of 4D anti de Sitter Einstein-Maxwell-Dilaton gravity. At finite temperature the field theory holographically dual to these solutions has a rich and interesting phenomenology reminiscent of electron motion in metals: phase transitions… -
Exact infinite-time statistics of the Loschmidt echo for a quantum quench
Paolo Zanardi - Institute for Scientific Interchange (ISI) Foundation
The equilibration dynamics of a closed quantum system is encoded in the long-time distribution function of generic observables. In this paper we consider the Loschmidt echo generalized to finite temperature, and show that we can obtain an exact expression for its long-time distribution for a closed… -
Non-equilibrium drive near a quantum critical point
Yong-Baek Kim - University of Toronto
We will discuss the effect of non-equilibrium drive near a quantum critical point in itinerant electron systems. Non-equilibrium field theory is formulated in terms of the Keldysh functional integral. The renormalization group approach is used to study the universality class of the non-equilibrium… -
Detecting Majorana Modes via Non-local Two Particle Interferometry
Pasquale Sodano - University of Perugia
We consider one dimensional devices supporting a pair of Majorana bound states at their ends We firstly show [1] that edge Majorana bound modes allow for processes with an actual transfer of electronic material between well-separated points and provide an explicit computation of the tunnelling… -
Simulation of Anyons Using Tensor Network Algorithms
Robert Pfeifer - Mosgiel Health Centre
The simulation of systems of anyons offers a significant challenge to the condensed matter physicist. These systems are presently of substantial theoretical and experimental interest due to their potential for universal quantum computation, but due to their non-trivial exchange statistics, the tools… -
Bringing order through disorder: Localization in the toric code
James Wootton - University of Leeds
Anderson localization emerges in quantum systems when randomised parameters cause the exponential suppression of motion. In this talk we will consider the localization phenomenon in the toric code, demonstrating its ability to sustain quantum information in a fault tolerant way. We show that an… -
Orthogonality catastrophe 40 years later: fidelity approach, criticality and boundary CFT
Lorenzo Campos Venuti - ISI, Turin
More than forty years ago Nobel laureate P.W. Anderson studied the overlap between two nearby ground states. The result that the overlap tends to zero in the thermodynamics limit was catastrophic for those times. More recently the study of the overlap between ground states, i.e. the fidelity, led to… -
1-loop diagram in AdS space and the random disorder problem
Yanwen Shang - Citigroup Incorporated
AdS/CFT has proven itself a powerful tool in extending our understanding of strongly coupled quantum theories. While studies of AdS/CFT have predominantly focused on tree level calculations, there has been growing interest in the loop effect recently. We studied the 1-loop correction to the gauge… -
Holographic Branching and Entanglement Renormalization
Glen Evenbly - Georgia Institute of Technology
Entanglement renormalization is a coarse-graining transformation for quantum lattice systems. It produces the multi-scale entanglement renormalization ansatz, a tensor network state used to represent ground states of strongly correlated systems in one and two spatial dimensions. In 1D, the MERA is… -
Torsion as a Probe in Condensed Matter Systems
Taylor Hughes - University of Illinois Urbana-Champaign
: In this talk I will review the common appearance of torsion in solids as well as some new developments. Torsion typically appears in condensed matter physics associated to topological defects known as dislocations. Now we are beginning to uncover new aspects of the coupling of torsion to materials… -
Mutual information and the structure of entanglement in quantum field theory
Brian Swingle - Brandeis University
In this talk I will describe my recent work on the structure of entanglement in field theory from the point of view of mutual information. I will give some basic scaling intuition for the entanglement entropy and then describe how this intuition is better captured by the mutual information. I will…
