Order parameter for non-mean-field spin glasses
Michele Castellana
We propose a novel renormalization group (RG) method for non mean-field models of spin glasses, which leads to the emergence of a novel order parameter. Unlike previous approaches…
Parallelization of Gillespie algorithm based on binary words
David Lacoste, Michele Castellana
We present an improvement of the Gillespie Exact Stochastic Simulation Algorithm, which leverages a bitwise representation of variables to perform independent simulations in parall…
Inverse modeling of time-delayed interactions via the dynamic-entropy formalism
Elena Agliari, Francesco Alemanno, Adriano Barra +3
Although instantaneous interactions are unphysical, a large variety of maximum entropy statistical inference methods match the model-inferred and the empirically-measured equal-tim…
On non-ideal chemical-reaction networks and phase separation
Ander Movilla Miangolarra, Michele Castellana
Much of the theory on chemical-reaction networks (CRNs) has been developed in the ideal-solution limit, where interactions between the solutes are negligible. However, there is a l…
Steric interactions and out-of-equilibrium processes control the internal organization of bacteria
Ander Movilla Miangolarra, Sophia Hsin-Jung Li, Jean-François Joanny +2
Despite the absence of a membrane-enclosed nucleus, the bacterial DNA is typically condensed into a compact body - the nucleoid. This compaction influences the localization and dyn…
Long-time diffusion and energy transfer in polydisperse mixtures of particles with different temperatures
Efe Ilker, Michele Castellana, Jean-François Joanny
Evidence suggests that the transport rate of a passive particle at long timescales is enhanced due to interactions with the surrounding active ones in a size- and composition-depen…
Reply to comment on 'Real-space renormalization-group methods for hierarchical spin glasses'
Michele Castellana
In their comment, Angelini et al. object to the conclusion of [J. Phys. A: Math. Theor., 52:445002, 2019] (1), where we show that in [Phys. Rev. B, 87:134201, 2013] the exponent $ν…
A statistical-inference approach to reconstruct inter-cellular interactions in cell-migration experiments
Elena Agliari, Pablo J. Sáez, Adriano Barra +3
Migration of cells can be characterized by two, prototypical types of motion: individual and collective migration. We propose a statistical-inference approach designed to detect th…
Real-space renormalization-group methods for hierarchical spin glasses
Michele Castellana
We focus on two real-space renormalization-group (RG) methods recently proposed for a hierarchical model of a spin glass: A sample-by-sample method, in which the RG transformation…
Symmetry reduction of the three-body problem based on Euler angles
Michele Castellana
We consider the classical three-body problem with an arbitrary pair potential which depends on the inter-body distance. A general three-body configuration is set by three "radial"…
Optimal localization patterns in bacterial protein synthesis
Jacky Nguyen, Michele Castellana
In bacterium, the molecular compounds involved in protein synthesis, messenger RNAs (mRNAs) and ribosomes, show marked intracellular localization patter…
Non-perturbative effects in spin glasses
Michele Castellana, Giorgio Parisi
We present a numerical study of an Ising spin glass with hierarchical interactions - the hierarchical Edwards-Anderson model with an external magnetic field (HEA). We study the mod…
Spatial organization of bacterial transcription and translation
Michele Castellana, Sophia Hsin-Jung Li, Ned S. Wingreen
In bacteria such as , DNA is compacted into a nucleoid near the cell center, while ribosomesmolecular complexes that translate messenger RNAs (mRNAs)…
Hierarchical spin glasses in a magnetic field: A renormalization-group study
Michele Castellana, Carlo Barbieri
By using renormalization-group (RG) methods, we study a non-mean-field model of a spin glass built on a hierarchical lattice, the hierarchical Edwards-Anderson model in a magnetic…
Entropic forces in a non-equilibrium system: Flocks of birds
Michele Castellana, William Bialek, Andrea Cavagna +1
When birds come together to form a flock, the distribution of their individual velocities narrows around the mean velocity of the flock. We argue that, in a broad class of models f…
Extreme-Value Distributions and the Freezing Transition of Structural Glasses
Michele Castellana
We consider two mean-field models of structural glasses, the random energy model (REM) and the -spin model (PSM), and we show that the finite-size fluctuations of the freezing t…
Rigorous Results for Hierarchical Models of Structural Glasses
Michele Castellana
We consider two non-mean-field models of structural glasses built on a hierarchical lattice. First, we consider a hierarchical version of the random energy model (HREM), and we pro…
Free-energy bounds for hierarchical spin models
Michele Castellana, Adriano Barra, Francesco Guerra
In this paper we study two non-mean-field spin models built on a hierarchical lattice: The hierarchical Edward-Anderson model (HEA) of a spin glass, and Dyson's hierarchical model…
Inverse spin glass and related maximum entropy problems
Michele Castellana, William Bialek
If we have a system of binary variables and we measure the pairwise correlations among these variables, then the least structured or maximum entropy model for their joint distribut…
The Renormalization Group for Disordered Systems
Michele Castellana
In this thesis we investigate the Renormalization Group (RG) approach in finite-dimensional glassy systems, whose critical features are still not well-established, or simply unknow…
Extreme Value Statistics Distributions in Spin Glasses
Michele Castellana, Aurelien Decelle, Elia Zarinelli
We study the probability distribution of the pseudo-critical temperature in a mean-field and in a short-range spin-glass model: the Sherrington-Kirkpatrick (SK) and the Edwards-And…
Real space Renormalization Group analysis of a non-mean field spin-glass
Michele Castellana
A real space Renormalization Group approach is presented for a non-mean field spin-glass. This approach has been conceived in the effort to develop an alternative method to the Ren…
Role of the Tracy-Widom distribution in the finite-size fluctuations of the critical temperature of the Sherrington-Kirkpatrick spin glass
Michele Castellana, Elia Zarinelli
We investigate the finite-size fluctuations due to quenched disorder of the critical temperature of the Sherrington-Kirkpatrick spin glass. In order to accomplish this task, we per…
Adversarial Satisfiability Problem
Michele Castellana, Lenka Zdeborová
We study the adversarial satisfiability problem, where the adversary can choose whether variables are negated in clauses or not in order to make the resulting formula unsatisfiable…
