Statistical mechanics of strings with Y-junctions
R. J. Rivers, D. A. Steer
We investigate the Hagedorn transitions of string networks with Y-junctions as may occur, for example, with (p,q) cosmic superstrings. In a simplified model with three different ty…
The disappearing operator
H. F. Jones, R. J. Rivers
In the Schroedinger formulation of non-Hermitian quantum theories a positive-definite metric operator must be introduced in order to ensure their probabilistic int…
On the Path-Integral Derivation of the Anomaly for the Hermitian Equivalent of the Complex -Symmetric Quartic Hamiltonian
H. F. Jones, J. Mateo, R. J. Rivers
It can be shown using operator techniques that the non-Hermitian -symmetric quantum mechanical Hamiltonian with a "wrong-sign" quartic potential is equivalent to a Herm…
Exploiting duality in a toy model of QCD at non-zero temperature and chemical potential: the massive Thirring model, sine-Gordon model and Coulomb gases
D. A. Steer, A. Gomez Nicola, R. J. Rivers +1
We focus on the massive Thirring model in 1+1 dimensions at finite temperature and non-zero chemical potential, and comment on some parallels between this model and QCD. In QCD, ca…
