Information and thermodynamics: Fast and precise approach to landauer's bound in an underdamped micromechanical oscillator

S Dago, J Pereda, N Barros, S Ciliberto, L Bellon - Physical Review Letters, 2021 - APS
The Landauer principle states that at least k BT ln 2 of energy is required to erase a 1-bit
memory, with k BT the thermal energy of the system. We study the effects of inertia on this …

Speed limit for a highly irreversible process and tight finite-time Landauer's bound

JS Lee, S Lee, H Kwon, H Park - Physical review letters, 2022 - APS
Landauer's bound is the minimum thermodynamic cost for erasing one bit of information. As
this bound is achievable only for quasistatic processes, finite-time operation incurs …

N Maccaferri - JOSA B, 2019 - opg.optica.org
We review the fundamental aspects and applications of functional magneto-optic and opto-
magnetic metamaterials displaying collective and coupling effects on the nanoscale, where …

Minimally dissipative information erasure in a quantum dot via thermodynamic length

M Scandi, D Barker, S Lehmann, KA Dick, VF Maisi… - Physical Review Letters, 2022 - APS
In this Letter, we explore the use of thermodynamic length to improve the performance of
experimental protocols. In particular, we implement Landauer erasure on a driven electron …

Dynamics of information erasure and extension of Landauer's bound to fast processes

S Dago, L Bellon - Physical Review Letters, 2022 - APS
Using a double-well potential as a physical memory, we study with experiments and
numerical simulations the energy exchanges during erasure processes, and model …

Finite-time landauer principle beyond weak coupling

A Rolandi, M Perarnau-Llobet - Quantum, 2023 - quantum-journal.org
Landauer's principle gives a fundamental limit to the thermodynamic cost of erasing
information. Its saturation requires a reversible isothermal process, and hence infinite time …

Direct measurement of weakly nonequilibrium system entropy is consistent with Gibbs–Shannon form

M Gavrilov, R Chétrite… - Proceedings of the …, 2017 - National Acad Sciences
Stochastic thermodynamics extends classical thermodynamics to small systems in contact
with one or more heat baths. It can account for the effects of thermal fluctuations and …

Adiabatic computing for optimal thermodynamic efficiency of information processing

S Dago, S Ciliberto, L Bellon - Proceedings of the National …, 2023 - National Acad Sciences
Landauer's principle makes a strong connection between information theory and
thermodynamics by stating that erasing a one-bit memory at temperature T 0 requires an …
