Two-Dimensional Solitons at Finite Temperature
M. Kacir, I. Zahed
The partition function of two-dimensional solitons in a heat bath of mesons is worked out to one-loop. For temperatures large compared to the meson mass, the free energy is dominat…

Hadrons and QCD Instantons: a Bosonized View
M. Kacir, M. Prakash, I. Zahed
In a dilute system of instantons and antiinstantons, the U(1) and scale anomalies are shown to be directly related to the bulk susceptibility and compressibility of the s…
