Multimode characterization of an optical beam deflection setup

Publikováno v: Phys. Rev. Applied 22, 014044 (2024)

Optical beam deflection is a popular method to measure the deformation of micromechanical devices. As it measures mostly a local slope, its sensitivity depends on the location and size of the optical spot. We present a method to evaluate precisely th

Linking fluctuation and dissipation in spatially extended out-of-equilibrium systems

Autor: Fontana, Alex, Bellon, Ludovic

Publikováno v: Phys. Rev. E 107, 034118 (2023)

For systems in equilibrium at a temperature $T$, thermal noise and energy damping are related to $T$ through the fluctuation-dissipation theorem (FDT). We study here an extension of the FDT to an out of equilibrium steady state: a microcantilever sub

Thermal noise of a cryo-cooled silicon cantilever locally heated up to its melting point

Autor: Fontana, Alex, Pedurand, Richard, Dolique, Vincent, Hansali, Ghaouti, Bellon, Ludovic

Publikováno v: Physical Review E : Statistical, Nonlinear, and Soft Matter Physics, American Physical Society, 2021, 103, pp.062125

The Fluctuation-Dissipation Theorem (FDT) is a powerful tool to estimate the thermal noise of physical systems in equilibrium. In general however, thermal equilibrium is an approximation, or cannot be assumed at all. A more general formulation of the

Extended equipartition in a mechanical system subject to a heat flow: the case of localised dissipation

Autor: Fontana, Alex, Pedurand, Richard, Bellon, Ludovic

Statistical physics in equilibrium grants us one of its most powerful tools: the equipartition principle. It states that the degrees of freedom of a mechanical system act as a thermometer: temperature is equal to the mean variance of their oscillatio

Investigating the Early-to-Late Mesolithic Transition in Northeastern Italy: A Multifaceted Regional Perspective

Autor: Fontana Federica, Visentin Davide, Bertola Stefano, Cristiani Emanuela, Dipino Noemi, Flor Elisabetta, Fontana Alex

Publikováno v: Open Archaeology, Vol 9, Iss 1, Pp 99-109 (2023)

This article focuses on the Mesolithic record of northeastern Italy, one of the key European regions for studying the last prehistoric hunter-gatherer groups. Most specifically, it aims to compare the rich Early and Late Mesolithic evidence, trying t
