Soft thermal diodes: grafted polymers provide a highly tunable thermal rectification
Claudio Pastorino, Alejandro Monastra, Florencia Carusela
We explore the heat-rectification properties of a two-phase fluid confined in a nano-chamber with one wall coated with end-grafted polymers using molecular-dynamics simulations. We…
Tuning ergodicity breaking: Anomalous diffusion under asymptotic power-law forcing
Raul V. B. Morás, M. Florencia Carusela, Luciano C. Lapas
In non-Markovian systems, distinct dynamical phases arise from the competition between internal memory and external forcing, encompassing thermalization, persistent ergodicity brea…
Temperature in Glass Slides: measurement using Phase Sensitive Optical Coherence Tomography and Computational Modeling
Jose M. Folgueiras, Lucas G. Chej, Luis L. Zurdo +4
Phase-sensitive optical coherence tomography (PhS-OCT) enables precise, contactless measurements of temperature-dependent changes in transparent solids. In this work, we used a com…
Transport of electrolytes across nanochannels: the role of slip
F. Carusela, J. Harting, P. Malgaretti
We characterize the electrokinetic flow due to the transport of electrolytes embedded in nanochannels of varying cross-section with inhomogeneous slip on their walls, modeled as an…
A non-homogeneous, non-stationary and path-dependent Markov anomalous diffusion model
Nestor Barraza, Gabriel Pena, Juliana Gambini +1
A novel probabilistic framework for modelling anomalous diffusion is presented. The resulting process is Markovian, non-homogeneous, non-stationary, non-ergodic, and state-dependen…
Modeling considerations about a microchannel heat sink
L. G. Chej, A. G. Monastra, M. F. Carusela
Many computational studies on hotspot microfluidic cooling devices found in the literature rely on simplified assumptions and conventions that do not capture the full complexity of…
Thermal diode assisted by geometry under cycling temperature
L. Zurdo, L. Chej, A. Monastra +1
Technological progress in electronics usually requires their use in increasingly aggressive environments, such as rapid thermal cycling and high power density. Thermal diodes appea…
Heat transport and cooling performance in a nanomechanical system with local and non local interactions
Natalia Beraha, M. Florencia Carusela, Alejandro Soba
In the present work, we study heat transport through a one dimensional time-dependent nanomechanical system. The microscopic model consists of coupled chains of atoms, considering…
Antiresonant driven systems for particle manipulation
M. Florencia Carusela, Paolo Malgaretti, J. Miguel Rubi
We report on the onset of anti-resonant behaviour of mass transport systems driven by time-dependent forces. Anti-resonances arise from the coupling of a sufficiently high number o…
Non-linear Fluctuating Hydrodynamics with many conserved fields: the case of a 3D anharmonic chain
Roberto Barreto, M. Florencia Carusela, Alejandro G. Monastra
We propose a model for a chain vibrating in 3 dimensions (3D), with first neighbors anharmonic interatomic potential which depends on their distance, and subjected to an external t…
Evolution of instabilities in filament buckling processes
A. G. Monastra, M. F. Carusela, G. van der Velde +2
In this work we study the dynamical buckling process of a thin filament immersed in a high viscous medium. We perform an experimental study to track the shape evolution of the fila…
Entropic rectification and current inversion in a pulsating channel
M. Florencia Carusela, J. Miguel Rubí
We show the existence of a resonant behavior of the current of Brownian particles confined in a pulsating channel. The interplay between the periodic oscillations of the shape of t…
Frequency thermal response and cooling performance in a microscopic system with a time-dependent perturbation
N. Beraha, A. Soba, M. F. Carusela
Following the nonequilibrium Green's function formalism we study the thermal transport in a composite chain subject to a time-dependent perturbation. The system is formed by two fi…
Thermal transport in a 2D stressed nanostructure with mass gradient
R. Barreto, M. F. Carusela, A. Mancardo Viotti +1
Inspired by some recent molecular dynamics (MD) simulations and experiments on suspended graphene nanoribbons, we study a simplified model where the atoms are disposed in a rectang…
Work and heat for two-level systems in dissipative environments: Strong driving and non-Markovian dynamics
Rebecca Schmidt, M. Florencia Carusela, Jukka P. Pekola +2
Work, moments of work and heat flux are studied for the generic case of a strongly driven twolevel system immersed in a bosonic heat bath in domains of parameter space where pertur…
Complementarity relation for irreversible processes near steady states
E. Sergio Santini, M. Florencia Carusela, Eduardo D. Izquierdo
A relation giving a minimum for the irreversible work in quasi-equilibrium processes was derived by Sekimoto et al. (K. Sekimoto and S. Sasa, J. Phys. Soc. Jpn. {\bf 66} (1997), 33…
Quantum phase diffusion in ac-driven superconducting atomic point contacts
M. Florencia Carusela, Joachim Ankerhold
The impact of quantum fluctuations on the phase diffusion in resistively shunted superconducting quantum points subject to an external ac-voltage is studied. Based on an extension…
