Published in 2017 at "Journal of High Energy Physics"

DOI: 10.1007/jhep01(2018)148

Abstract: A bstractWe construct a hierarchy of integrable systems whose Poisson structure corresponds to the BMS3 algebra, and then discuss its description in terms of the Riemannian geometry of locally flat spacetimes in three dimensions.The analysis… read more here.

Published in 2021 at "Geometriae Dedicata"

DOI: 10.1007/s10711-021-00629-8

Abstract: Cauchy-compact flat spacetimes with extreme BTZ are Lorentzian analogue of complete hyperbolic surfaces of finite volume. Indeed, the latter are 2-manifolds locally modeled on the hyperbolic plane, with group of isometries $$\mathrm {PSL}_2(\mathbb {R})$$ ,… read more here.

Published in 2025 at "Progress of Theoretical and Experimental Physics"

DOI: 10.1093/ptep/ptaf174

Abstract: We explore spacetimes with multiple energy injections in asymptotically flat two-dimensional black hole and analyze the entanglement entropy in such spacetimes. This work is an extension of the setup of the single-injection case, by F. F. Gautason,… read more here.

Published in 2020 at "Physical Review D"

DOI: 10.1103/physrevd.101.125009

Abstract: A new class of conformal field theories is presented, where the background gravitational field is conformally flat. Conformally flat (CF) spacetimes enjoy conformal properties quite similar to the ones of flat spacetime. The conformal isometry… read more here.

Published in 2018 at "Physical Review D"

DOI: 10.1103/physrevd.98.046003

Abstract: We use the complexity equals action proposal to calculate the rate of complexity growth for field theories that are the holographic duals of asymptotically flat spacetimes. To this aim, we evaluate the on-shell action of… read more here.

Published in 2019 at "Modern Physics Letters A"

DOI: 10.1142/s0217732319503486

Abstract: We develop a technique relating scalar fields with different masses in different conformally flat spacetimes. We apply this technique to the case of FRW spacetimes, with [Formula: see text], and discuss several examples. We also… read more here.
