The mechanisms which give rise to Hawking radiation are revealed by analyzing in detail pair production in the presence of horizons. In preparation for the black hole problem, three preparatoryâ€¦ (More)

Although the laws of thermodynamics are well established for black hole horizons, much less has been said in the literature to support the extension of these laws to more general settings such as anâ€¦ (More)

We measured the power spectrum and two-point correlation function for the randomly fluctuating free surface on the downstream side of a stationary flow with a maximum Froude number F_{max}â‰ˆ0.85â€¦ (More)

We compute the transition amplitudes between charged particles of mass M and m accelerated by a constant electric field and interacting by the exchange of quanta of a third field. We work in secondâ€¦ (More)

The surface gravity of any Killing horizon, in any spacetime dimension , can be interpreted as a local, two-dimensional expansion rate seen by freely falling observers when they cross the horizon.â€¦ (More)

The energy and particle fluxes emitted by an accelerated two level atom are analysed in detail. It is shown both perturbatively and non perturbatively that the total number of emitted photons isâ€¦ (More)

The recoils of an accelerated system caused by the transitions characterizing thermal equilibrium are taken into account through the quantum character of the position of the system. The specificâ€¦ (More)

We prove that the Heisenberg-Euler-Schwinger mechanism â€“pair creation in a constant electric fieldâ€“ and its radiative corrections imply the Unruh effect, i.e. the thermalisation of acceleratedâ€¦ (More)

In this Letter we study the gravitational interactions between outgoing configurations giving rise to Hawking radiation and in-falling configurations. When the latter are in their ground state, theâ€¦ (More)
