Instability of Non-Commutative SYM Theories at Finite Temperature / Landsteiner, Karl (CERN) ; Lopez, Esperanza (CERN) ; Tytgat, Michel H.G. (Brussels U.)
We extend our previous work on the quasi-particle excitations in N=4 non-commutative U(1) Yang-Mills theory at finite temperature. We show that above some critical temperature there is a tachyon in the spectrum of excitations. [...]

Excitations in Hot Non-Commutative Theories / Landsteiner, Karl (CERN) ; Lopez, Esperanza (CERN) ; Tytgat, Michel H.G. (CERN)
We study the dispersion relation for scalar excitations in supersymmetric, non-commutative theories at finite temperature. In N=4 Yang-Mills the low momenta modes have superluminous group velocity. [...]

Quasi-Particles in Non-Commutative Field Theory / Landsteiner, Karl (CERN)
After a short introduction to the UV/IR mixing in non-commutative field theories we review the properties of scalar quasi-particles in non-commutative supersymmetric gauge theories at finite temperature. In particular we discuss the appearance of super-luminous wave propagation..

A Note on Interactions of (Non-Commutative) Instantons Via AdS/CFT / Barbon, J.L.F. (CERN) ; Pasquinucci, A. (Milan U. ; Milan Bicocca U. ; INFN, Milan)
We consider the interaction between instantons and anti-instantons in four-dimensional N=4 super-Yang-Mills theory at large N and large 't Hooft coupling as described by D-instantons via AdS/CFT duality. We give an estimate of the strength of the interaction in various regimes. [...]
