Quantum Thermodynamics

The study of the interactions between thermodynamics and quantum mechanics is known as quantum thermodynamics. The two distinct theories discuss the fundamental properties of matter and light. Albert Einstein made the claim in 1905 that the need for consistency between electromagnetism and thermodynamics leads to the conclusion that light is quantized, so achieving the connection. The beginning of quantum theory is this publication. In a few decades, quantum theory developed its own set of recognised laws. At the moment, quantum thermodynamics deals with how thermodynamic laws come from quantum mechanics. In that it places more focus on dynamical processes out of equilibrium, it varies from quantum statistical mechanics. There is also an effort to make the theory applicable to a single quantum system.
