Driven quantum systems exhibit a large variety of interesting and sometimes exotic phenomena. In this talk, I study driven two-dimensional conformal field theories from spacetime and quantum information geometric points of view. First, I show that a large class of driving protocols can be realized by coupling the CFT to a time-dependent background spacetime metric. I will do this in the...
In recent years the search for a holographic duality, which is based on tessellations of the hyperbolic plane has gained momentum and the construction of suitable boundary theories has been considered in the literature. We propose a discrete analog of JT gravity, defined on hyperbolic lattices as a dual bulk theory. We calculate the partition function in the Schwarzian regime, through an...
In this talk I investigate a quantum circuit in a two-dimensional conformal field theory whose generating Hamiltonian includes primary fields. The motivation in the context of AdS/CFT is to access new bulk geometries dual to simple quantum circuits. The gate set of the boundary circuits, based on the stress tensor in previous work, is expanded through the inclusion of primary fields. I will...
In four spacetime dimensions, soft theorems concerning the factorization of amplitudes with soft gravitons are related to the BMS asymptotic symmetries of the spacetime. In particular, subleading soft theorems are associated to the BMS transformations usually called superrotations. They identify a scattering mode that behaves at the boundary like the stress tensor of a two-dimensional...
In light of recent advancements made towards quantifying quantum chaos in dynamical systems, and motivated by the search for viable definitions of complexity in quantum field theory and holography, we revisit quantum billiards and examine the recently proposd measure of Krylov state complexity known as spread complexity. In particular, we investigate the growth of Krylov state complexity in...
