Open Science @ UniMiB: nasce il sito di Ateneo dedicato alla scienza aperta

Open Science @ UniMiB (openscience.unimib.it) è il nuovo sito web di informazione, formazione e servizi promosso dall’Ateneo in materia di Open Science.
Il progetto nasce con l'obiettivo di aumentare la consapevolezza degli utenti di Bicocca sulla presenza di competenze e strumenti a supporto dell’Open Science, fornire notizie e approfondimenti inerenti all’intero ecosistema della Scienza Aperta, creare una community di utenti informata e proattiva.

Energy Transport for Thick Holographic Branes

Universal properties of two-dimensional conformal interfaces are encoded by the flux of energy transmitted and reflected during a scattering process. We develop an innovative method that allows us to use results for the energy transmission in thin-brane holographic models to find the energy transmission for general smooth domain-wall solutions of three-dimensional gravity. Our method is based on treating the continuous geometry as a discrete set of branes. As an application, we compute the tr...

Conformal Carroll scalars with boosts

We construct two distinct actions for scalar fields that are invariant under local Carroll boosts and Weyl transformations. Conformal Carroll field theories were recently argued to be related to the celestial holography description of asymptotically flat spacetimes. However, only few explicit examples of such theories are known, and they lack local Carroll boost symmetry on a generic curved background. We derive two types of conformal Carroll scalar actions with boost symmetry on a curved bac...

Shape deformations of charged Rényi entropies from holography

Charged and symmetry-resolved Rényi entropies are entanglement measures quantifying the degree of entanglement within different charge sectors of a theory with a conserved global charge. We use holography to determine the dependence of charged Rényi entropies on small shape deformations away from a spherical or planar entangling surface in general dimensions. This dependence is completely characterized by a single coefficient appearing in the two point function of the displacement operator as...

Nonrelativistic near-BPS corners of N = 4 super-Yang-Mills with SU(1, 1) symmetry

We consider limits of N = 4 super Yang-Mills (SYM) theory that approach BPS bounds and for which an SU(1,1) structure is preserved. The resulting near-BPS theories become non-relativistic, with a U(1) symmetry emerging in the limit that implies the conservation of particle number. They are obtained by reducing N = 4 SYM on a three-sphere and subsequently integrating out fields that become non-dynamical as the bounds are approached. Upon quantization, and taking into account normal-ordering, t...

The Panorama of Spin Matrix theory

Spin Matrix theory describes near-BPS limits of N = 4 SYM theory, which enables us to probe finite N effects like D-branes and black hole physics. In previous works, we have developed the spherical reduction and spin chain methods to construct Spin Matrix theory for various limits. In this paper, by considering a supercharge Q which is cubic in terms of the letters, we construct the Hamiltonian of the largest Spin Matrix theory of N = 4 SYM, called the PSU(1, 2|3) Spin Matrix theory, as H= {Q...
