Dark spots along slowly scaling chains of plasmonic nanoparticles
Gianluigi Zito, Giulia Rusciano, Antonio Sasso
We numerically investigate the optical response of slowly scaling linear chains of mismatched silver nanoparticles. Hybridized plasmon chain resonances manifest unusual local field…
Simultaneous measurements of electrophoretic and dielectrophoretic forces using optical tweezers
Giuseppe Pesce, Giulia Rusciano, Gianluigi Zito +1
Herein, charged microbeads handled with optical tweezers are used as a sensitive probe for simultaneous measurements of electrophoretic and dielectrophoretic forces. We first deter…
Surface charge and hydrodynamic coefficient measurements of {\it Bacillus subtilis} spore by Optical Tweezers
Giuseppe Pesce, Giulia Rusciano, Antonio Sasso +3
In this work we report on the simultaneous measurement of the hydrodynamic coefficient and the electric charge of single {\it Bacillus subtilis} spores. The latter has great import…
Influence of rotational force fields on the determination of the work done on a driven Brownian particle
Giuseppe Pesce, Giovanni Volpe, Alberto Imparato +2
For a Brownian system the evolution of thermodynamic quantities is a stochastic process. In particular, the work performed on a driven colloidal particle held in an optical trap ch…
Quantitative assessment of non-conservative radiation forces in an optical trap
Giuseppe Pesce, Giorgio Volpe, Anna Chiara De Luca +2
The forces acting on an optically trapped particle are usually assumed to be conservative. However, the presence of a non-conservative component has recently been demonstrated. Her…
Work and heat probability distribution of an optically driven Brownian particle: Theory and experiments
A. Imparato, L. Peliti, G. Pesce +2
We analyze the equations governing the evolution of distributions of the work and the heat exchanged with the environment by a manipulated stochastic system, by means of a compact…
