Seçkin Kürkçüoglu (Hannover):
Quantum Aspects of the Noncommutative Sine-Gordon Model
Abstract:
In this talk,
I will first present some of the quantum field theoretical
aspects of the integrable noncommutative sine-Gordon
model proposed in [hep-th/0406065] using standard semi-classical
methods. In particular, I will discuss the fluctuations
at quadratic order around the static kink solution using
the background field method. I will argue that at O(θ2)
the spectrum of fluctuations remains essentially the
same as that of the corresponding commutative theory.
A brief analysis of one-loop two-point functions will
also be presented and it will be followed by some remarks
on the obstacles in determining the noncommutativity
corrections to the quantum mass of the kink.
