Tuesday 26th February: STP Seminar – “Thermodynamics of precision in quantum non-equilibrium steady states”
Title: “Thermodynamics of precision in quantum non-equilibrium steady states”
Speaker: Dr. Giacomo Guarnieri (TCD)
Abstract: We investigate the fundamental trade-off between current fluctuations and entropy production for systems in non-equilibrium steady states (NESS). We use the technique of non-equilibrium statistical operators of McLennan/Zubarev form and illustrate how the entropy production can be expressed as a quantum relative entropy. Furthermore, by exploiting the geometry of the manifold of NESS states, we use parameter estimation in order to bound the co-variance of the currents in the NESS by the entropy production. Since our proof is geometrical, this fundamental result generalizes the thermodynamics of precision and the thermodynamic uncertainly beyond the classical Markovian paradigm. This result promises to evolve our understanding of the delicate relationship between fluctuations and quantum coherence in autonomous thermal machines.

While there is an obvious @DIASDunsink link, there is another #DIAS link to this event. Pictured on the right here you will see @TomRayDIAS with his daughter @Emma_Ray_Artist whose own flash of creativity won the commission in 2018.
What a day yesterday! Amazing autumnal sunshine for not only the Hamilton walk but the official unveiling of the new artwork commemorating William Rowan Hamilton's "eureka" moment at what is now Broombridge luas stop.
Wow! This image from an article published in August is from a group lead by Ruben Fedriani. It is a result of work undertaken while at DIAS is now a featured image on @NatureComms site! It is a striking.
Excellent work Ruben and team!
