Physicists have extended one of the most prominent fluctuation theorems of classical stochastic thermodynamics, the Jarzynski equality, to quantum field theory. As quantum field theory is considered to be the most fundamental ...
For most everyday experiences, such as riding a bicycle, using a lift or catching a ball, classical (Newtonian) mechanics is perfectly accurate.

(ScienceX)—It was another good week for physics as an international team of researchers discovered strange forces acting on nanoparticles, which were related to looking at the Casimir Effect using quantum field theory. ...
A new scientific paper published, in part, by a University of New Mexico physicist is shedding light on a strange force impacting particles at the smallest level of the material world.
