The High Energy, Cosmology and Astroparticle Physics (HECAP) section at ICTP is studying some of the most exciting areas in physics today, from string theory to physics at large energy colliders, from neutrino phenomenology to alternative cosmologies.
HECAP collaborates closely with the staff of the International School for Advanced Studies (SISSA), the Department of Theoretical Physics of Trieste University, and with the physicists of the Trieste section of the Italian National Institute of Nuclear Physics (INFN).

Bulk entanglement entropy for photons and gravitons in AdS_3/CFT_2
Abstract. In this talk, I will discuss holographic entanglement entropy beyond the classical limit. The classical contribution to the entanglement entropy is given by the area of the Ryu-Takayanagi surface, and Faulkner, Lewkowycz and Maldacena showed that the quantum corrections arise from the bulk entanglement entropy across the RT surface. All fields in the low-energy effective field theory contribute to the bulk entanglement entropy, including gauge fields and gravitons for which it is notoriously difficult to factorize the Hilbert space. I will consider the bulk entanglement entropy for photons and gravitons in AdS_3/CFT_2, which enables an exact computation due to the topological nature of the degrees of freedom. In the vacuum where the CFT answer is fixed by symmetry, I will show that the effect of the bulk entanglement entropy is to renormalize Newton's constant. For excited states, I will show a perfect agreement between the bulk and CFT answers.

The HECAP section has research and visitors' programmes, including postdoctoral fellowships, mostly aimed at scientists from developing countries.
The main motivation to study string theory is because it promises to provide a framework to unify all matter and interactions, including gravity, in a consistent theory. Despite the intrinsic difficulty of dealing with a theory that manifests itself at scales as high as the Planck mass, for more than 25 years there has been continuous progress in order to connect string theory and low-energy physics. This refers to extensions of the Standard Model of particle physics and cosmology that could lead to some observable implications.
