Coarse-Graining via Lumping: Exact Calculations and Fundamental Limitations
Gianluca Teza, Attilio L. Stella, Trevor GrandPre
Detecting broken time-reversibility at micro- and nanoscale is often difficult when experiments offer limited state resolution. We introduce a lumping method that builds an effecti…
Finite-temperature criticality through quantum annealing
Gianluca Teza, Francesco Campaioli, Marco Avesani +1
Critical phenomena at finite temperature underpin a broad range of physical systems, yet their study remains challenging due to computational bottlenecks near phase transitions. Qu…
Speedups in nonequilibrium thermal relaxation: Mpemba and related effects
Gianluca Teza, John Bechhoefer, Antonio Lasanta +2
Most of our intuition about the behavior of physical systems is shaped by observations at or near thermal equilibrium. However, even a thermal quench can lead to states far from th…
Direct estimates of irreversibility from time series
Trevor GrandPre, Gianluca Teza, William Bialek
The arrow of time can be quantified through the Kullback-Leibler divergence () between the distributions of forward and reverse trajectories in a system. Many approaches to…
Universal and non-universal signatures in the scaling functions of critical variables
Gianluca Teza, Attilio L. Stella
The view that the probability density function (PDF) of a key statistical variable, anomalously scaled by size or time, could furnish a hallmark of universal behavior contrasts wit…
Universal singularities of anomalous diffusion in the Richardson class
Attilio L. Stella, Aleksei Chechkin, Gianluca Teza
Inhomogeneous environments are rather ubiquitous in nature, often implying anomalies resulting in deviation from Gaussianity of diffusion processes. While sub- and superdiffusion a…
Anomalous dynamical scaling determines universal critical singularities
Attilio L. Stella, Aleksei Chechkin, Gianluca Teza
Anomalous diffusion phenomena occur on length scales spanning from intracellular to astrophysical ranges. A specific form of decay at large argument of the probability density func…
Eigenvalue crossing as a phase transition in relaxation dynamics
Gianluca Teza, Ran Yaacoby, Oren Raz
When a system's parameter is abruptly changed, a relaxation towards the new equilibrium of the system follows. We show that a crossing between the second and third eigenvalues of t…
Far from equilibrium relaxation in the weak coupling limit
Ran Yaacoby, Oren Raz, Gianluca Teza
It is commonly assumed that a large system, weakly coupled to a thermal environment through its boundaries, relaxes quasistatically towards the new equilibrium even when the temper…
Relaxation shortcuts through boundary coupling
Gianluca Teza, Ran Yaacoby, Oren Raz
When a hot system cools down faster than an equivalent cold one, it exhibits the Mpemba Effect. This counterintuitive phenomenon was observed in several systems including water, ma…
Exact Coarse Graining Preserves Entropy Production out of Equilibrium
Gianluca Teza, Attilio L. Stella
The entropy production rate associated with broken time-reversal symmetry provides an essential characterization of nanosystems out of equilibrium, from driven colloidal particles…
Rate dependence of current and fluctuations in jump models with negative differential mobility
Gianluca Teza, Stefano Iubini, Marco Baiesi +2
Negative differential mobility is the phenomenon in which the velocity of a particle decreases when the force driving it increases. We study this phenomenon in Markov jump models w…
