Nonanalytic Structure of Effective Potential at Finite Temperature on Compactified Space
Makoto Sakamoto, Kazunori Takenaga
We thoroughly investigate nonanalytic terms in the finite-temperature effective potential in one-loop approximation on a -dimensional spacetime, $S_τ\times R^{D-(p+1)}\times \pr…
Mode Recombination Formula and Nonanalytic Term in Effective Potential at Finite Temperature on Compactified Space
Makoto Sakamoto, Kazunori Takenaga
We develop a new formula called a mode recombination formula, and we can recast the effective potential at finite temperature in one-loop approximation for fermion and scalar field…
Non-analytic Term in Effective Potential at Finite Temperature for Scalar Field on Compactified Space
Makoto Sakamoto, Kazunori Takenaga
We study non-analytic terms, which cannot be written in the form of any positive integer power of field-dependent mass squared, in effective potential at finite temperature in one-…
5d Dirac fermion on quantum graph
Yukihiro Fujimoto, Tomonori Inoue, Makoto Sakamoto +2
In this paper, we investigate a five-dimensional Dirac fermion on a quantum graph that consists of a single vertex and loops. We find that the model possesses a rich structure…
Polyakov Loop in Non-covariant Operator Formalism
Makoto Sakamoto, Kazunori Takenaga
We discuss a Polyakov loop in non-covariant operator formalism which consists of only physical degrees of freedom at finite temperature. It is pointed out that although the Polyako…
High Temperature Symmetry Nonrestoration and Inverse Symmetry Breaking on Extra Dimensions
Makoto Sakamoto, Kazunori Takenaga
We study -dimensional gauge theory with an extra dimension of a circle at finite temperature. We mainly focus on the expectation value of the gauge field for the direction of th…
