Casimir Energies due to Matter Fields in T 2 and T 2 / Z 2 Compactifications
نویسنده
چکیده
We calculate the Casimir energies due to matter fields with various boundary conditions along two compact directions in T 2 compactification. We discuss whether the Casimir energies generate attractive or repulsive forces. On the theories with extra dimensions, the Casimir energy plays a crucial role in the mechanism for stabilizing the size of extra dimensions. Finally we argue a procedure of the application to Z2 orbifold. ∗E-mail address: [email protected] 1

Casimir Forces due to Matters in Compactified Six Dimensions
We calculate the Casimir energies due to matters with various boundary conditions along two compact directions in six-dimensional T 2 compactification. We discuss whether the Casimir forces are attractive or repulsive forces. On the theories with extra dimensions, the Casimir energy plays a crucial role in the mechanism for stabilizing the size of extra dimensions. Finally we argue a procedure ...
متن کاملGauge Couplings and their M – Theory Origin
We work out the relation between automorphic forms on SO(2+s, 2, Z) and gauge one– loop corrections of heterotic K3×T 2 string compactifications for the cases s = 0, 1. We find that one–loop gauge corrections of any orbifold limit of K3 with arbitrary choice of gauge bundles can always be expressed by their instanton numbers and generic automorphic forms. These functions classify also one–loop ...

The free energy due to the vacuum fluctuations of matter fields on a classical gravitational background is discussed. It is shown explicitly how this energy is calculated for a non-minimally coupled scalar field in an arbitrary gravitational background, using the heat kernel method. The treatment of (self-)interacting fields of higher spin is outlined, using a meanfield approximation to the gau...
متن کاملStandard model with compactified spatial dimensions
The standard model coupled to gravity has a unique fourdimensional vacuum. Nevertheless, in case of one spatial dimension compactified on a circle [1], or for two spatial dimensions compactified on a 2-torus, it has recently been shown that there may also exist lower-dimensional vacua stabilized by the Casimir energies of the standard model particles with the lowest mass, i.e., gravitons, photo...

We work out the relation between automorphic forms on SO(2 + s, 2, Z) and gauge one–loop corrections of heterotic K3×T 2 string compactifications for the cases s = 0, 1. We find that one–loop gauge corrections of any orbifold limit of K3 can always be expressed by their instanton numbers and generic automorphic forms. These functions classify also one– loop gauge thresholds of N=1 (0, 2) hetero...
