Non-perturbative calculations of a global U(1) theory at finite density and temperature
T. S. Evans, H. F. Jones, D. Winder
We use an optimised hopping parameter expansion for the free energy (linear delta expansion) to study the phase transitions at finite temperature and finite charge density in a glo…

Quantum Dynamics of the Slow Rollover Transition in the Linear Delta Expansion
H. F. Jones, P. Parkin, D. Winder
We apply the linear delta expansion to the quantum mechanical version of the slow rollover transition which is an important feature of inflationary models of the early universe. Th…
