Polymer quantization, singularity resolution and the 1/r^2 potential
G. Kunstatter, J. Louko, J. Ziprick
We present a polymer quantization of the -lambda/r^2 potential on the positive real line and compute numerically the bound state eigenenergies in terms of the dimensionless couplin…
Quantum gravity and the Coulomb potential
Viqar Husain, Jorma Louko, Oliver Winkler
We apply a singularity resolution technique utilized in loop quantum gravity to the polymer representation of quantum mechanics on R with the singular -1/|x| potential. On an equis…
A new expression for the transition rate of an accelerated particle detector
J. Louko, A. Satz
We analyse the instantaneous transition rate of an accelerated Unruh-DeWitt particle detector whose coupling to a quantum field on Minkowski space is regularised by a finite spatia…
Excited by a quantum field: Does shape matter?
Jorma Louko, Alejandro Satz
The instantaneous transition rate of an arbitrarily accelerated Unruh-DeWitt particle detector on four-dimensional Minkowski space is ill defined without regularisation. We show th…
Transgressing the horizons: Time operator in two-dimensional dilaton gravity
Gabor Kunstatter, Jorma Louko
We present a Dirac quantization of generic single-horizon black holes in two-dimensional dilaton gravity. The classical theory is first partially reduced by a spatial gauge choice…
How often does the Unruh-DeWitt detector click? Regularisation by a spatial profile
Jorma Louko, Alejandro Satz
We analyse within first-order perturbation theory the instantaneous transition rate of an accelerated Unruh-DeWitt particle detector whose coupling to a massless scalar field on fo…
