Role of coherence in quantum-dot-based nanomachines within the Coulomb blockade regime
Federico D. Ribetto, Raúl A. Bustos-Marún, Hernan L. Calvo
During the last decades, quantum dots within the Coulomb blockade regime of transport have been proposed as essential building blocks for a wide variety of nanomachines. This inclu…
Entropy current and efficiency of quantum machines driven by nonequilibrium incoherent reservoirs
Sebastian E. Deghi, Raúl A. Bustos-Marún
Nanotechnology has not only provided us the possibility of developing quantum machines but also noncanonical power sources able to drive them. Here we focus on studying the perform…
Theoretical Analysis of Metallic-Nanodimer Thermoplasmonics for Phototactic Nanoswimmers
Andrés I. Bertoni, Nicolás Passarelli, Raúl Bustos-Marún
We assess the potentiality of several geometries of metallic nanodimers (one of the simplest thermoplasmonic systems) as candidates for active particles (nanoswimmers) propelled an…
Lasing Conditions of Transverse Electromagnetic Modes in Metallic-Coated Micro- and Nanotubes
Nicolás Passarelli, Raúl Bustos-Marún, Ricardo Depine
In this work, we study the lasing conditions of the transverse electric (TE) modes of micro- and nanotubes coated internally with a thin metallic layer. This geometry may tackle so…
Nonequilibrium current-induced forces caused by quantum localization: Anderson Adiabatic Quantum Motors
Lucas J. Fernández-Alcázar, Horacio M. Pastawski, Raúl A. Bustos-Marún
In recent years there has been an increasing interest in nanomachines. Among them, current-driven ones deserve special attention as quantum effects can play a significant role ther…
Geometric rectification for nanoscale vibrational energy harvesting
Raúl A. Bustos-Marún
In this work, we present a mechanism that, based on quantum-mechanical principles, allows one to recover kinetic energy at the nanoscale. Our premise is that very small mechanical…
Real-time diagrammatic approach to current-induced forces: Application to quantum-dot based nanomotors
Hernan L. Calvo, Federico D. Ribetto, Raúl A. Bustos-Marún
During the last years there has been an increasing excitement in nanomotors and particularly in current-driven nanomotors. Despite the broad variety of stimulating results found, t…
Dynamics and decoherence in nonideal Thouless quantum motors
Lucas J. Fernández-Alcázar, Horacio M. Pastawski, Raúl A. Bustos-Marún
Different proposals for adiabatic quantum motors (AQMs) driven by DC currents have recently attracted considerable interest. However, the systems studied are often based on simplif…
Spaser and optical amplification conditions in gold-coated active nanoparticles
Nicolás Passarelli, Raúl A. Bustos-Marún, Eduardo A. Coronado
Due to their many potential applications, there is an increasing interest in studying hybrid systems composed of optically active media and plasmonic metamaterials. In this work we…
Decoherence in current induced forces: Application to adiabatic quantum motors
Lucas J. Fernández-Alcázar, Raúl A. Bustos-Marún, Horacio M. Pastawski
Current induced forces are not only related with the discrete nature of electrons but also with its quantum character. It is natural then to wonder about the effect of decoherence.…
Tailoring optical fields emitted by nanometric sources
Raúl A. Bustos-Marún, Axel D. Dente, Eduardo A. Coronado +1
Here we study a simple way of controlling the emitted fields of sub-wavelength nanometric sources. The system consists of arrays of nanoparticles (NPs) embedded in optical active m…
Excitation-Transfer Plasmonic Nanosensors based on Dynamical Phase Transitions
Raúl A. Bustos-Marún, Eduardo A. Coronado, Horacio M. Pastawski
Dynamical Phase transitions (DPTs) describe the abrupt change in the dynamical properties of open systems when a single control parameter is slightly modified. Recently we found th…
Crucial role of decoherence for electronic transport in molecular wires: Polyaniline as a case study
Carlos J. Cattena, Raúl A. Bustos-Marún, Horacio M. Pastawski
In this work we attempt to elucidate the nature of conductivity in polymers by taking the acid-base doped polyaniline (PAni) polymer. We evaluate the PAni conductance by using real…
