Instantons in Four-Fermi Term Broken SUSY with General Potential
Agapitos Hatzinikitas, Ioannis Smyrnakis
It is shown how to solve the Euclidean equations of motion of a point particle in a general potential and in the presence of a four-Fermi term. The classical action in this theory…
Closed Bosonic String Partition Function in Time Independent Exact PP-Wave Background
Agapitos Hatzinikitas, Ioannis Smyrnakis
The modular invariance of the one-loop partition function of the closed bosonic string in four dimensions in the presence of certain homogeneous exact pp-wave backgrounds is studie…
Boundary Structure and Module Decomposition of the Bosonic Orbifold Models with
Agapitos Hatzinikitas, Ioannis Smyrnakis
The bosonic orbifold models with compactification radius are examined in the presence of boundaries. Demanding the extended algebra characters to have definite con…
Boundary States, Extended Symmetry Algebra and Module Structure for certain Rational Torus Models
Ioannis Smyrnakis
The massless bosonic field compactified on the circle of rational is reexamined in the presense of boundaries. A particular class of models corresponding to $R^2=\frac{1}{2k}…
Noncommutative Quantization in 2D Conformal Field Theory
Agapitos Hatzinikitas, Ioannis Smyrnakis
The simplest possible noncommutative harmonic oscillator in two dimensions is used to quantize the free closed bosonic string in two flat dimensions. The partition function is not…
The noncommutative harmonic oscillator in more than one dimensions
Agapitos Hatzinikitas, Ioannis Smyrnakis
The noncommutative harmonic oscillator in arbitrary dimension is examined. It is shown that the -genvalue problem can be decomposed into separate harmonic oscillator equatio…
