Gauge-invariant scalar and field strength correlators in 3d
M. Laine, O. Philipsen
Gauge-invariant non-local scalar and field strength operators have been argued to have significance, e.g., as a way to determine the behaviour of the screened static potential at l…
Scalar-gauge dynamics in (2+1) dimensions at small and large scalar couplings
O. Philipsen, M. Teper, H. Wittig
We present the results of a detailed calculation of the excitation spectrum of states with quantum numbers J^{PC}=0++, 1-- and 2++ in the three-dimensional SU(2) Higgs model at two…
Connecting Higgs and Confinement Phase of the 3d SU(2) Higgs Model
O. Philipsen
The mass spectrum of the 3d SU(2) Higgs model for states with quantum numbers , and as obtained from lattice simulations is presented in the Higgs and con…
The finite temperature real time \hbar^2 corrections in quantum mechanics
D. Bodeker, M. Laine, O. Philipsen
We study non-perturbative real time correlation functions at finite temperature. In order to see whether the classical term gives a good approximation in the high temperature limit…
