Fuzzy measurements and coarse graining in quantum many-body systems
Carlos Pineda, David Davalos, Carlos Viviescas +1
Using the quantum map formalism, we provide a framework to construct fuzzy and coarse grained quantum states of many-body systems that account for limitations in the resolution of…

Wigner function in the polariton phase space
A. Rosado, E. Sadurní, J. M. Torres
The Wigner function of a dynamical infinite dimensional lattice is studied. A closed differential equation without diffusion terms for this function is obtained and solved. We map…

Diffraction of particles in free fall
D. Condado, J. L. Díaz-Cruz, A. Rosado +1
The problem of a beam of quantum particles falling through a diffractive screen is studied. The solutions for single and double slits are obtained explicitly when the potential is…
