Heat distribution of quantum fields interacting with Unruh-DeWitt detectors
Marcos L. W. Basso, Alberto Saa
We introduce an operational framework for heat-exchange statistics between a quantum field and an Unruh-DeWitt detector in Minkowski spacetime. Using an interferometric protocol, w…
Isochrone spacetimes
Alberto Saa, Roberto Venegeroles
We introduce the relativistic version of the well-known Henon's isochrone spherical models: static spherically symmetrical spacetimes in which all bounded trajectories are isochron…
A new derivation of the Henon's isochrone potentials
Alberto Saa, Roberto Venegeroles
We revisit in this note the Hénon's isochrone problem. By using the standard Abel inversion technique for one-dimensional motion, we recover in a simple way the Hénon's parabolae a…
Higher-dimensional Euclidean and non-Euclidean structures in planar circuit quantum electrodynamics
Alberto Saa, Eduardo Miranda, Francisco Rouxinol
We show that a recent proposal for simulating planar hyperbolic lattices with circuit quantum electrodynamics can be extended to accommodate also higher dimensional lattices in Euc…
Post-Newtonian Hamiltonian dynamics: applications to stationary spacetimes and statistical mechanics
Ronaldo S. S. Vieira, Javier Ramos-Caro, Alberto Saa
Although the post-Newtonian Lagrangian formalism is widely used in relativistic dynamical and statistical studies of test bodies moving around arbitrary mass distributions, the cor…
Quasinormal modes and self-adjoint extensions of the Schroedinger operator
Júlio C. Fabris, Martín G. Richarte, Alberto Saa
We revisit here the analytical continuation approach usually employed to compute quasinormal modes (QNM) and frequencies of a given potential barrier starting from the bounded…
