Wigner Analysis of Particle Dynamics and Decoherence in Wide Nonharmonic Potentials
Andreu Riera-Campeny, Marc Roda-Llordes, Piotr T. Grochowski +1
We derive an analytical expression of a Wigner function that approximately describes the time evolution of the one-dimensional motion of a particle in a nonharmonic potential. Our…
Numerical Simulation of Large-Scale Nonlinear Open Quantum Mechanics
Marc Roda-Llordes, Davide Candoli, Piotr T. Grochowski +5
We introduce a numerical method to simulate nonlinear open quantum dynamics of a particle in situations where its state undergoes significant expansion in phase space while generat…
Macroscopic Quantum Superpositions via Dynamics in a Wide Double-Well Potential
Marc Roda-Llordes, Andreu Riera-Campeny, Davide Candoli +2
We present an experimental proposal for the rapid preparation of the center of mass of a levitated particle in a macroscopic quantum state, that is a state delocalized over a lengt…
Large Quantum Delocalization of a Levitated Nanoparticle using Optimal Control: Applications for Force Sensing and Entangling via Weak Forces
T. Weiss, M. Roda-Llordes, E. Torrontegui +2
We propose to optimally control the harmonic potential of a levitated nanoparticle to quantum delocalize its center-of-mass motional state to a length scale orders of magnitude lar…
Quantum Size Effects in the Magnetic Susceptibility of a Metallic Nanoparticle
M. Roda-Llordes, C. Gonzalez-Ballestero, A. E. Rubio López +3
We theoretically study quantum size effects in the magnetic response of a spherical metallic nanoparticle (e.g. gold). Using the Jellium model in spherical coordinates, we compute…
