The influence of the Casimir effect on the binding potential for 3D wetting
Alessio Squarcini, José M. Romero-Enrique, Andrew O. Parry
We provide comprehensive details of how a previously overlooked entropic, or low temperature Casimir contribution, , to the total binding potential for 3D short-ranged wetting…
The Casimir effect in wetting layers
Alessio Squarcini, José M. Romero-Enrique, Andrew O. Parry
For a long time, the study of thermal effects at three-dimensional (3D) short-ranged wetting transitions considered only the effect of interfacial fluctuations. We show that an ent…
Noise-to-signal ratio of single-trajectory spectral densities in centered Gaussian processes
Alessio Squarcini, Enzo Marinari, Gleb Oshanin +2
We discuss the statistical properties of a single-trajectory power spectral density of an arbitrary real-valued centered Gaussian process , where is th…
Frequency-frequency correlations of single-trajectory spectral densities of Gaussian processes
Alessio Squarcini, Enzo Marinari, Gleb Oshanin +2
We investigate the stochastic behavior of the single-trajectory spectral density of several Gaussian stochastic processes, i.e., Brownian motion, the Ornstein-Uh…
Casimir contribution to the interfacial Hamiltonian for 3D wetting
Alessio Squarcini, José M. Romero-Enrique, Andrew O. Parry
Previous treatments of three-dimensional (3D) short-ranged wetting transitions have missed an entropic or low temperature Casimir contribution to the binding potential describing t…
Fractional Brownian Gyrator
Alessio Squarcini, Alexandre Solon, Pascal Viot +1
When a physical system evolves in a thermal bath at a constant temperature, it arrives eventually to an equilibrium state whose properties are independent of the kinetic parameters…
Spectral density of individual trajectories of an active Brownian particle
Alessio Squarcini, Alexandre Solon, Gleb Oshanin
We study analytically the single-trajectory spectral density (STSD) of an active Brownian motion as exhibited, for example, by the dynamics of a chemically-active Janus colloid. We…
Inhomogeneous surface tension of chemically active fluid interfaces
Alessio Squarcini, Paolo Malgaretti
We study the dependence of the surface tension of a fluid interface on the density profile of a third suspended phase. By means of an approximated model for the binary mixture and…
Passive advection of fractional Brownian motion by random layered flows
Alessio Squarcini, Enzo Marinari, Gleb Oshanin
We study statistical properties of the process of a passive advection by quenched random layered flows in situations when the inter-layer transfer is governed by a fractiona…
Curvature corrections to the nonlocal interfacial model for short-ranged forces
Jose M. Romero-Enrique, Alessio Squarcini, Andrew O. Parry +1
In this paper we revisit the derivation of a nonlocal interfacial Hamiltonian model for systems with short-ranged intermolecular forces. Starting from a microscopic Landau-Ginzburg…
Power spectral density of a single Brownian trajectory: What one can and cannot learn from it
Diego Krapf, Enzo Marinari, Ralf Metzler +3
The power spectral density (PSD) of any time-dependent stochastic processes is a meaningful feature of its spectral content. In its text-book definition, the PSD is the Fouri…
