TODAY at 14h00! Qls seminar by Francesco COGHI - Level 2.5 large deviations and uncertainty relations for non-Markov self-interacting dynamics

[Quantitative Life Sciences]

Dear All,

Today, Tuesday, 31 March  at 14:00 CET, Francesco Coghi (University of 
Nottingham/, /UK) will give a seminar titled:

*"Level 2.5 large deviations and uncertainty relations for non-Markov 
self-interacting dynamics"

*Abstract:

elf-interacting jump processes are stochastic systems where transition 
rates depend on the process' own empirical occupation measure—the  
time-averaged distribution over visited states—introducing a feedback 
that breaks Markovianity. In this talk, I will present a large deviation 
framework for such systems. I will derive the level-2.5 rate functional 
for the joint fluctuations of occupation measure and probability flux, 
constructed via exponential tilting extended to the non-Markovian 
setting. I will then show how memory modifies fluctuation bounds, 
yielding kinetic and thermodynamic uncertainty relations that generalise 
their Markov counterparts. Depending on time, I will close with one or 
two examples illustrating how feedback reshapes fluctuation-dissipation 
trade-offs.



The seminar will take place in the Common Area, 2nd floor, old SISSA 
building (Via Beirut, 2).
You are all most welcome to attend!

Best regards,

Erica
