Weyl Curvature Evolution System for GR

Kirill Krasnov, Adam Shaw

Starting from the chiral first-order pure connection formulation of General Relativity, we put the field equations of GR in a strikingly simple evolution system form. The two dynam…

Thermodynamic geometry of ideal quantum gases: a general framework and a geometric picture of BEC-enhanced heat engines

Joshua Eglinton, Tuomas Pyharanta, Keiji Saito +1

Thermodynamic geometry provides a physically transparent framework to describe thermodynamic processes in meso- and micro-scale systems that are driven by slow variations of extern…

Radio jet-ISM interaction and positive radio-mechanical feedback in Abell 1795

Prathamesh D. Tamhane, Brian R. McNamara, Helen R. Russell +8

We present XSHOOTER observations with previous ALMA, MUSE and observations to study the nature of radio-jet triggered star formation and the interaction of radio jets with th…

Probing quasar lifetimes with proximate -centimetre absorption in the diffuse intergalactic medium at redshifts

Tomáš Šoltinský, James S. Bolton, Margherita Molaro +5

Enhanced ionizing radiation in close proximity to redshift quasars creates short windows of intergalactic Ly transmission blueward of the quasar Ly emission line…

The graviton four-point function in de Sitter space

James Bonifacio, Harry Goodhew, Austin Joyce +2

We compute the tree-level late-time graviton four-point correlation function, and the related quartic wavefunction coefficient, for Einstein gravity in de Sitter spacetime. We deri…

Entanglement resolution of free Dirac fermions on a torus

Alessandro Foligno, Sara Murciano, Pasquale Calabrese

Whenever a system possesses a conserved charge, the density matrix splits into eigenspaces associated to the each symmetry sector and we can access the entanglement entropy in a gi…
