We show that the stress-energy tensor has additional terms with respect to the ideal form in states of global thermodynamic equilibrium in flat spacetime with non-vanishing acceleration and vorticity. These corrections are of quantum origin and their leading terms are second order in the gradients of the thermodynamic fields. Their relevant coefficients can be expressed in terms of correlators...

By establishing a relation between information erasure and continuous phase transitions we generalise the Landauer bound to analog computing systems. The entropy production per degree of freedom during erasure of an analog variable (reset to standard value) is given by the logarithm of the configurational volume measured in units of its minimal quantum. As a consequence every computation has...

We continue the study of the Quench Action Method (QAM) for a recently considered geometrical quantum quench: two free fermionic chains initially separated by an hard wall and after put in contact and let evolve unitarily with a translation invariant Hamiltonian. Every time un unbalanced of energy, chemical potential or number of particles is present two different stationary regimes are...

The AdS/Ricci-flat correspondence connects families of asymptotically AdS spacetimes to Ricci-flat spacetimes, and can be used to transfer tools and results between them. In its original formulation, this map requires a high degree of symmetry, limiting its possible applications. I will show how to extend the correspondence to a larger class of spacetimes, that includes for example general...

In this talk, I propose a new model that supports two-dimensional topological phases. The tight-binding model defined on the Lieb lattice with three different species of fermions supports a single Dirac-like point in the momentum space. The dispersion relation around this point is fully relativistic and described by a Duffin-Kemmer-Petiau Hamiltonian. I show the presence of topologically...
