Free energies of triply and quadruply degenerate electron ladder spectra
Minghao Li, Zehua Sun, Klavs Hansen
The electronic free energies in metal clusters are calculated based on a simple ladder spectrum for the level degeneracies three and four, and compared with the known results for d…
Planar chirality and optical spin-orbit coupling for chiral Fabry-Perot cavities
Jérôme Gautier, Minghao Li, Thomas W. Ebbesen +1
We design, in a most simple way, Fabry-Perot cavities with longitudinal chiral modes by sandwiching between two smooth metallic silver mirrors a layer of polystyrene made planar ch…
Galilean relativity for Brownian dynamics and energetics
Minghao Li, Oussama Sentissi, Stefano Azzini +1
We study experimentally the impact of inertial reference frame changes on overdamped Brownian motion. The reference frame changes are implemented by inducing, with a laser, laminar…
Noise and ergodic properties of Brownian motion in an optical tweezer: looking at the crossover between Wiener and Ornstein-Uhlenbeck processes
Rémi Goerlich, Minghao Li, Samuel Albert +3
We characterize throughout the spectral range of an optical trap the nature of the noise at play and the ergodic properties of the corresponding Brownian motion of an overdamped tr…
Subfemtonewton force fields measured with ergodic Brownian ensembles
Minghao Li, Oussama Sentissi, Stefano Azzini +3
We demonstrate that radiation pressure force fields can be measured and reconstructed with a resolution of fN (at a confidence level) using an ergodic ensemble of ov…
