Fluctuation theorems with optical tweezers: theory and practice
Thalyta T. Martins, André H. A. Malavazi, Lucas P. Kamizaki +4
Fluctuation theorems, such as the Jarzynski equality and the Crooks relation, are effective tools connecting non-equilibrium work statistics and equilibrium free energy differences…
Cavity nano-optomechanics with suspended subwavelength-sized nanowires
Antoine Reigue, Francesco Fogliano, Philip Heringlake +5
In the field of cavity nano-optomechanics, the nanoresonator-in-the-middle approach consists in inserting a sub-wavelength sized deformable resonator, here a nanowire, in the small…
Benchmark of the Schmiedl-Seifert optimal protocol with reduced dissipated work and fluctuations in optical tweezers
Thalyta Tavares Martins, André H. A. Malavazi, Lucas Prado Kamizaki +4
Finite-time thermodynamic transformations generally dissipate energy, as required by the Second Law, so identifying and investigating energetically optimal processes remain relevan…

We study experimentally and theoretically the optimal mean time needed by a free diffusing Brownian particle to reach a target at a distance L from an initial position in the prese…
Cavity nano-optomechanics in the ultrastrong coupling regime with ultrasensitive force sensors
Francesco Fogliano, Benjamin Besga, Antoine Reigue +6
In a canonical optomechanical system, mechanical vibrations are dynamically encoded on an optical probe field which reciprocally exerts a backaction force. Due to the weak single p…

The ultimate sensitivities achieved in force or mass sensing are limited by the employed nanomechanical probes thermal noise. Its proper understanding is critical for ultimate oper…
