Memory-aware acceleration of orientational dynamics in nanoparticle suspensions
Miguel Ibáñez, Raúl A. Rica-Alarcón, María L. Jiménez
The relaxation of stochastic systems after sudden perturbations is constrained by speed limits and often reveals memory effects that hinder attempts to accelerate their dynamics. H…
The cost of speed: Time-optimal thermal control of trapped Brownian particles
Miguel Ibanez, Antonio Patron-Castro, Antonio Lasanta +3
A thermal analogue of the classical brachistochrone problem, which minimizes the connection time between two equilibrium states of harmonically confined Brownian particles, has rec…
Hybrid dielectrophoretic-optical trap for microparticles in aqueous suspension
Carlos D. Gonzalez-Gomez, Jose Garcia-Guirado, Romain Quidant +3
We demonstrate that a set of microfabricated electrodes can be coupled to a commercial optical tweezers device, implementing a hybrid electro-optical trap with multiple functionali…
Universal relations and bounds for fluctuations in quasistatic small heat engines
Kosuke Ito, Guo-Hua Xu, Chao Jiang +4
The efficiency of any heat engine, defined as the ratio of average work output to heat input, is bounded by Carnot's celebrated result. However, this measure is insufficient to cha…
