Munshi G. Mustafa, in his recent publication in EPJ ST, introduces thermal field theory, an essential subset of quantum field theory that focuses on phenomena occurring at non-zero temperatures. This theory combines statistical mechanics with conventional quantum field theory and simplifies the examination of many-body systems. It is vital for understanding high-energy heavy-ion collisions, phase transitions in condensed matter physics, and early universe evolution.
Thermal field theory seeks to explain many-body dynamics at non-zero temperatures not considered in conventional quantum field theory.
The thermal field theory, as presented by Munshi G. Mustafa, bridges statistical mechanics and quantum field theory, simplifying the analysis of many-body systems and enhancing the understanding of high-energy collisions and early universe evolution.
Quantum field theory is a framework used by physicists to describe a wide range of phenomena in particle physics and is an effective tool to deal with complicated many-body problems or interacting systems.
Conventional quantum field theory describes systems and interactions at zero temperature and zero chemical potential, and interactions in the real world certainly do occur at non-zero temperatures.
That means scientists are keen to discover what effects may arise as a result of non-zero temperature and what new phenomena could arise due to a thermal background. In order to understand this, physicists turn to a recipe for quantum field theory in a thermal background — thermal field theory. READ MORE...
