The Strong Levinson Theorem for the Dirac Equation
Alex Calogeracos, Norman Dombey
We consider the Dirac equation in one space dimension in the presence of a symmetric potential well. We connect the scattering phase shifts at E=+m and E=-m to the number of states…
Recalculation of the spectrum of radiation emitted during gravitational collapse
Alex Calogeracos
We recalculate the spectrum of radiation emitted from a collapsing star. We consider the simple model of a spherical star consisting of pressure-free dust and we derive the thermal…
A detailed recalculation of the spectrum of radiation emitted during gravitational collapse of a spherically symmetric star
Alex Calogeracos
We address the question of radiation emitted from a collapsing star. We consider the simple model of a spherical star consisting of pressure-free dust and we derive the emission sp…
Radiation from perfect mirrors following prescribed relativistic trajectories
A. Calogeracos
The question is examined of a mirror which starts from rest and either (i) accelerates for some time and eventually reverts to motion at constant velocity, or (ii) continues accele…
Radiation from perfect mirrors starting from rest and the black body spectrum
A. Calogeracos
We address the question of radiation emission from a perfect mirror that starts from rest and follows the trajectory z=-ln(cosht) till t->Infinity. We show that a correct derivatio…
Radiation from accelerated perfect or dispersive mirrors following prescribed relativistic asymptotically inertial trajectories
A Calogeracos
We address the question of radiation emission from both perfect and dispersive mirrors following prescribed relativistic trajectories. The trajectories considered are asymptoticall…
