Extracting work optimally with imprecise measurements
L. Dinis, J. M. R. Parrondo
Measurement and feedback allows an external agent to extract work from a system in contact with a single thermal bath. The maximum amount of work that can be extracted in a single…
Thermodynamics of Information
Juan M. R. Parrondo
As early as 1867, two years after the introduction of the concept of entropy by Clausius, Maxwell showed that the limitations imposed by the second law of thermodynamics depend on…
Comment on "Inferring broken detailed balance in the absence of observable currents"
Gili Bisker, Ignacio A. Martinez, Jordan M. Horowitz +1
In this reply, we resolve the apparent discrepancy raised in the "Comment on Inferring broken detailed balance in the absence of observable currents" [arXiv:2112.08978v1]. We stres…
Inferring broken detailed balance in the absence of observable currents
Ignacio A. Martínez, Gili Bisker, Jordan M. Horowitz +1
Identifying dissipation is essential for understanding the physical mechanisms underlying nonequilibrium processes. {In living systems, for example, the dissipation is directly rel…
Heating without heat: thermodynamics of passive energy filters between finite systems
Ramón Muñoz-Tapia, Ricardo Brito, Juan M. R. Parrondo
Passive filters allowing the exchange of particles in a narrow band of energy are currently used in micro-refrigerators and energy transducers. In this letter, we analyze their the…
Maxwell demons in phase space
Juan M. R. Parrondo, Léo Granger
Although there is not a complete "proof" of the second law of thermo- dynamics based on microscopic dynamics, two properties of Hamiltonian systems have been used to prove the impo…
Brownian Carnot engine
Ignacio A. Martínez, Édgar Roldán, Luis Dinis +3
The Carnot cycle imposes a fundamental upper limit to the efficiency of a macroscopic motor operating between two thermal baths. However, this bound needs to be reinterpreted at mi…
Transverse ratchet effect and superconducting vortices: Simulation and experiment
L. Dinis, D. Perez de Lara, E. M. Gonzalez +3
A transverse ratchet effect has been measured in magnetic/superconducting hybrid films fabricated by electron beam lithography and magnetron sputtering techniques. The samples are…
Universal features in the energetics of symmetry breaking
Edgar Roldan, Ignacio A Martinez, Juan MR Parrondo +1
A symmetry breaking (SB) involves an abrupt change in the set of microstates that a system can explore. This change has unavoidable thermodynamic implications. According to Boltzma…
Optimizing non-ergodic feedback engines
Jordan M. Horowitz, Juan M. R. Parrondo
Maxwell's demon is a special case of a feedback controlled system, where information gathered by measurement is utilized by driving a system along a thermodynamic process that depe…
Entropy production along nonequilibrium quantum jump trajectories
Jordan M. Horowitz, Juan M. R. Parrondo
For classical nonequilibrium systems, the separation of the total entropy production into the adiabatic and nonadiabatic contributions is useful for understanding irreversibility i…
Imitating Chemical Motors with Optimal Information Motors
Jordan M. Horowitz, Takahiro Sagawa, Juan M. R. Parrondo
To induce transport, detailed balance must be broken. A common mechanism is to bias the dynamics with a thermodynamic fuel, such as chemical energy. An intriguing, alternative stra…
Designing optimal discrete-feedback thermodynamic engines
Jordan M. Horowitz, Juan M. R. Parrondo
Feedback can be utilized to convert information into useful work, making it an effective tool for increasing the performance of thermodynamic engines. Using feedback reversibility…
Thermodynamic Reversibility in Feedback Processes
Jordan M. Horowitz, Juan M. R. Parrondo
The sum of the average work dissipated plus the information gained during a thermodynamic process with discrete feedback must exceed zero. We demonstrate that the minimum value of…
Cooling classical particles with a microcanonical Szilard engine
Rahul Marathe, J. M. R. Parrondo
We discuss the possibility of extraction of energy from a single heat bath in a cyclic process, under some special initial conditions. We give an explicit example in which a system…
Current reversal in collective ratchets induced by lattice instability
L. Dinis, E. M. Gonzalez, J. V. Anguita +2
A collective mechanism for current reversal in superconducting vortex ratchets is proposed. The mechanism is based on a two-dimensional instability of the ground state (T=0) of the…
Closed-loop control strategy with improved current for a flashing ratchet
L. Dinis, J. M. R. Parrondo, F. J. Cao
We show how to switch on and off the ratchet potential of a collective Brownian motor, depending only on the position of the particles, in order to attain a current higher than or…
Feedback control in a collective flashing ratchet
F. J. Cao, L. Dinis, J. M. R. Parrondo
An ensemble of Brownian particles in a feedback controlled flashing ratchet is studied. The ratchet potential is switched on and off depending on the position of the particles, wit…
Paradoxical games and Brownian thermal engines
J. M. R. Parrondo, B. J. de Cisneros
Two losing games, when alternated in a periodic or random fashion, can produce a winning game. This paradox occurs in a family of stochastic processes: if one combines two or more…
Optimal strategies in collective Parrondo games
Luis Dinis, Juan M. R. Parrondo
We present a modification of the so-called Parrondo's paradox where one is allowed to choose in each turn the game that a large number of individuals play. It turns out that, by ch…
New paradoxical games based on Brownian ratchets
Juan M. R. Parrondo, Gregory P. Harmer, Derek Abbott
Based on Brownian ratchets, a counter-intuitive phenomenon has recently emerged -- namely, that two losing games can yield, when combined, a paradoxical tendency to win. A restrict…
Efficiency of Brownian Motors
J. M. R. Parrondo, J. M. Blanco, F. J. Cao +1
The efficiency of different types of Brownian motors is calculated analytically and numerically. We find that motors based on flashing ratchets present a low efficiency and an unav…
