FRG analysis for a relativistic BEC in arbitrary spatial dimensions
Fumio Terazaki, Kazuya Mameda
A relativistic Bose-Einstein condensate (BEC) is studied within the complex scalar field theory using the functional renormalization group (FRG) under the local potential approxima…

Relativistic BEC extracted from a complex FRG flow equation
Fumio Terazaki, Kazuya Mameda, Katsuhiko Suzuki
Based on the functional renormalization group (FRG) under the local potential approximation, we analyze the Bose-Einstein condensation (BEC) in the relativistic complex scalar theo…
