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_Ï\times R^{D-(p+1)}\times \p…

Stochastic quantization with discrete fictitious time
Daisuke Kadoh, Mitsuhiro Kato, Makoto Sakamoto +1
We present a new approach to stochastic quantization à la Parisi-Wu with a discrete fictitious time. The noise average is modified by weights, which results in the equivalence in t…

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…
