Work as an external quantum observable and an operational quantum work fluctuation theorem
Konstantin Beyer, Kimmo Luoma, Walter T. Strunz
We propose a definition of externally measurable quantum work in driven systems. Work is given as a quantum observable on a control device which is forcing the system and can be de…

Steering heat engines: a truly quantum Maxwell demon
Konstantin Beyer, Kimmo Luoma, Walter T. Strunz
We address the question of verifying the quantumness of thermal machines. A Szilárd engine is truly quantum if its work output cannot be described by a local hidden state (LHS) mod…

Axion-like-particle decay in strong electromagnetic backgrounds
B. King, B. M. Dillon, K. A. Beyer +1
The decay of a massive pseudoscalar, scalar and U(1) boson into an electron-positron pair in the presence of strong electromagnetic backgrounds is calculated. Of particular interes…
