Unified treatment of the total angular momentum of single photons via generalized quantum observables
Mario Motta, Giacomo Guarnieri, Ludovico Lanz +1
In this paper we provide a consistent framework to address the notorious decomposition of the single-photon total angular momentum (TAM) into a spin (SAM) and an orbital (OAM) comp…
Quantum work statistics and resource theories: bridging the gap through Renyi divergences
G. Guarnieri, N. H. Y. Ng, K. Modi +3
The work performed on or extracted from a non-autonomous quantum system described by means of a two-point projective-measurement approach takes the form of a stochastic variable. W…
Steady-state coherences by composite system-bath interactions
Giacomo Guarnieri, Michal Kolar, Radim Filip
We identify sufficient conditions on the structure of the interaction Hamiltonian between a two-level quantum system and a thermal bath which, without any external drive or coheren…
