Localized Conduction Channels in Memristors

KS Woo, RS Williams, S Kumar - Chemical Reviews, 2024 - ACS Publications
Since the early 2000s, the impending end of Moore's scaling, as the physical limits to
shrinking transistors have been approached, has fueled interest in improving the …

General theory of static response for markov jump processes

T Aslyamov, M Esposito - Physical Review Letters, 2024 - APS
We consider Markov jump processes on a graph described by a rate matrix that depends on
various control parameters. We derive explicit expressions for the static responses of edge …

Nonequilibrium response for markov jump processes: Exact results and tight bounds

T Aslyamov, M Esposito - Physical Review Letters, 2024 - APS
Generalizing response theory of open systems far from equilibrium is a central quest of
nonequilibrium statistical physics. Using stochastic thermodynamics, we develop an …

Dissipation bounds precision of current response to kinetic perturbations

K Ptaszyński, T Aslyamov, M Esposito - Physical Review Letters, 2024 - APS
The precision of currents in Markov networks is bounded by dissipation via the so-called
thermodynamic uncertainty relation (TUR). In our Letter, we demonstrate a similar inequality …

Macroscopic stochastic thermodynamics

G Falasco, M Esposito - arXiv preprint arXiv:2307.12406, 2023 - arxiv.org
Starting at the mesoscopic level with a general formulation of stochastic thermodynamics in
terms of Markov jump processes, we identify the scaling conditions that ensure the …

Nonequilibrium fluctuation-response relations: From identities to bounds

T Aslyamov, K Ptaszyński, M Esposito - arXiv preprint arXiv:2410.17140, 2024 - arxiv.org
In nonequilibrium steady states of Markov jump processes, we derive exact Fluctuation-
Response Relations (FRRs) that express the covariance between any pair of currents in …

Laser-induced ultrafast spin-transfer processes in non-linear zigzag carbon chain systems

M Barhoumi, J Liu, G Lefkidis, W Hübner - … Chemistry Chemical Physics, 2023 - pubs.rsc.org
We combine the high-level quantum chemistry theory CCSD and EOM-CCSD together with
local and global Λ processes to investigate the details of the laser-induced ultrafast spin …

Dynamical signatures of discontinuous phase transitions: How phase coexistence determines exponential versus power-law scaling

K Ptaszyński, M Esposito - Physical Review E, 2024 - APS
There are conflicting reports in the literature regarding the finite-size scaling of the
Liouvillian gap and dynamical fluctuations at discontinuous phase transitions, with various …

Information flows in macroscopic Maxwell's demons

N Freitas, M Esposito - Physical Review E, 2023 - APS
A CMOS-based implementation of an autonomous Maxwell's demon was recently proposed
[Phys. Rev. Lett. 129, 120602 (2022) 0031-9007 10.1103/PhysRevLett. 129.120602] to …

Thermodynamic cost of precise timekeeping in an electronic underdamped clock

A Gopal, M Esposito, N Freitas - Physical Review B, 2024 - APS
Clocks are inherently out-of-equilibrium because, due to friction, they constantly consume
free energy to keep track of time. The thermodynamic uncertainty relation (TUR) quantifies …
