On the geometry of quantum complexity
ASC Workshops - April 06, 2021 16:18 - 1 hour - Video ★★★★★ - 1 ratingComputational complexity is a quantum information concept that recently has found applications in holography. I will consider quantum computational complexity for n qubits using Nielsen's geometrical approach. In the definition of complexity there is a big amount of arbitrariness due to the choic...

Orbifolds of 4d N=2 supersymmetric gauge theories
ASC Workshops - April 06, 2021 16:18 - 1 hour - Video ★★★★★ - 1 ratingAfter recalling how some 4d N=2 gauge theories arise from reductions of 6d N=(2,0) superconformal theories on a Riemann surface, I will discuss two discrete quotients with codimension 2 orbifold singularities. In the first case the orbifold acts by rotations around one plane of the 4d N=2 theory;...
Page Curve from Holographic Moving Mirror and End of the World brane
ASC Workshops - April 06, 2021 16:18 - 58 minutes - Video ★★★★★ - 1 ratingIn this talk we calculate the entanglement entropy in the presence of a moving mirror in a CFT. We employ the AdS/BCFT construction to describe a gravity dual of moving mirrors. We will show that the time evolution of entanglement entropy for a class of moving mirror, which models an evaporating ...
Phases of Holographic Interfaces
ASC Workshops - April 06, 2021 16:18 - 1 hour - Video ★★★★★ - 1 ratingDomain walls between Anti-de Sitter vacua are important for the study of the string-theory landscape, and enter in recent toy models of black hole evaporation. In this talk I will describe the phase diagram of a simple 2+1 dimensional model of thin domain walls anchored at the AdS boundary, and I...
Pole skipping away from maximal chaos
ASC Workshops - April 06, 2021 16:18 - 59 minutes - Video ★★★★★ - 1 ratingThe pole skipping phenomenon is a subtle effect in the thermal energy density retarded two point function at a special point in the complex frequency and momentum planes. For maximally chaotic theories, this special point is related to data characterising the butterfly effect, and is explained b...

Quantum BTZ black hole and Outlook
ASC Workshops - April 06, 2021 16:18 - 2 hours - Video ★★★★★ - 1 ratingThe study of quantum effects on black holes including their gravitational backreaction is an important but notoriously hard problem. I will begin by reviewing how the framework of braneworld holography allows to solve it for strongly-coupled quantum conformal fields. Then I will describe a hologr...
Quantum Complexity, Integrability, and Chaos
ASC Workshops - April 06, 2021 16:18 - 1 hour - Video ★★★★★ - 1 ratingQuantum Complexity, Integrability, and Chaos The states of quantum systems grow in complexity over time as entanglement spreads between degrees of freedom. Following ideas in computer science, we formulate the complexity of evolution as the length of the shortest geodesic on the unitary group ma...

Saturons
ASC Workshops - April 06, 2021 16:18 - 59 minutes - Video ★★★★★ - 1 ratingWe introduce the concept of saturons, systems that saturate a certain bound on entropy, which is imposed by S-matrix and unitarity. Such objects share certain niversal properties (e.g., the area-law of entropy, near-thermal emission, inner entanglement, ...) that goes well beyond gravity. We giv...
Six-dimensional CFTs and M5-branes
ASC Workshop Series - July 26, 2019 14:25 - 1 hour - VideoI will review some recent progress on six-dimensional conformal field theories, highlighting applications to the dynamics of M5-branes. On an orbifold singularity, M5s can fractionate, and they can recombine by sometimes leaving behind a 'frozen' version of the singularity. The CFTs describing th...
