Orientational Ordering of Janus Particle Arrays as Classical Compass Spin Systems
Zhijie Fan, Myeonggon Park, Marija Vucelja +1
Janus-particle arrays provide a soft-matter platform in which particle orientations act as classical spins with anisotropic, bond-dependent interactions. Motivated by recent experi…
Thermalization packets and optimal ice cubes
Israel Klich, Marija Vucelja
Relaxation toward equilibrium is usually accelerated by modifying the environment or by cooling a system further from equilibrium. Here we introduce a distinct strategy: thermaliza…
Extending the Mpemba effect to the underdamped realm
Shahaf Aharony Shapira, Gene Chen, Marija Vucelja +1
The Mpemba effect is the counterintuitive phenomenon in which an initially hotter system cools faster than a colder, otherwise identical system. It has been experimentally demonstr…
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…
Effect of dynamics on anomalous thermal relaxations and information exchange
Saikat Bera, Matthew R. Walker, Marija Vucelja
The Mpemba effect, an example of anomalous thermal relaxations, occurs when a system prepared at a hot temperature overtakes an identical system prepared at a warm temperature and…
Optimal transport and anomalous thermal relaxations
Matthew R. Walker, Saikat Bera, Marija Vucelja
We study connections between optimal transport and anomalous thermal relaxations. A prime example of anomalous thermal relaxations is the Mpemba effect, which occurs when a hot sys…
Mpemba effect in terms of mean first passage time
Matthew R. Walker, Marija Vucelja
The Mpemba effect occurs when a system prepared at a hot temperature cools down faster to the bath temperature than an identical system starting at a warm temperature. We derive th…
Nonreversible Markov chain Monte Carlo algorithm for efficient generation of Self-Avoiding Walks
Hanqing Zhao, Marija Vucelja
We introduce an efficient nonreversible Markov chain Monte Carlo algorithm to generate self-avoiding walks with a variable endpoint. In two dimensions, the new algorithm slightly o…
Anomalous thermal relaxation of Langevin particles in a piecewise-constant potential
Matthew Walker, Marija Vucelja
We consider the thermal relaxation of a particle in a piecewise-constant potential landscape subject to thermal fluctuations in the overdamped limit. We study the connection betwee…
Solution of the Metropolis dynamics on a complete graph with application to the Markov chain Mpemba effect
Israel Klich, Marija Vucelja
We find analytically the complete set of eigenvalues and eigenvectors associated with Metropolis dynamics on a complete graph. As an application, we use this information to study a…
Memory effect and phase transition in a hierarchical trap model for spin glass
Depei Zhang, Tianran Chen, Marija Vucelja +2
We introduce an efficient dynamical tree method that enables us, for the first time, to explicitly demonstrate thermo-remanent magnetization memory effect in a hierarchical energy…
The Mpemba index and anomalous relaxation
Israel Klich, Oren Raz, Ori Hirschberg +1
The Mpemba effect is a counter-intuitive relaxation phenomenon, where a system prepared at a hot temperature cools down faster than an identical system initiated at a cold temperat…
Dynamics of adaptive immunity against phage in bacterial populations
Serena Bradde, Marija Vucelja, Tiberiu Tesileanu +1
The CRISPR (clustered regularly interspaced short palindromic repeats) mechanism allows bacteria to adaptively defend against phages by acquiring short genomic sequences (spacers)…
Lifting -- A nonreversible Markov chain Monte Carlo Algorithm
Marija Vucelja
Markov chain Monte Carlo algorithms are invaluable tools for exploring stationary properties of physical systems, especially in situations where direct sampling is unfeasible. Comm…

Marija Vucelja, Konstantin S. Turitsyn, Michael Chertkov
We analyze the statistics of work generated by a gradient flow to stretch a nonlinear polymer. We obtain the Large Deviation Function (LDF) of the work in the full range of appropr…
Emergence of clones in sexual populations
Richard A. Neher, Marija Vucelja, Marc Mézard +1
In sexual population, recombination reshuffles genetic variation and produces novel combinations of existing alleles, while selection amplifies the fittest genotypes in the populat…

Marija Vucelja, Gregory Falkovich, Konstantin S. Turitsyn
We consider a passive scalar field under the action of pumping, diffusion and advection by a smooth flow with a Lagrangian chaos. We present theoretical arguments showing that scal…

We present a model for the Lagrangian dynamics of inertial particles in a compressible flow, where fluid velocity gradients are modelled by a telegraph noise. The model allows for…
Weak compressibility of surface wave turbulence
M. Vucelja, I. Fouxon
We study the growth of small-scale inhomogeneities of the density of particles floating in weakly nonlinear, small-amplitude, surface waves. Despite the amplitude smallness, the ac…
Clustering of matter in waves and currents
M. Vucelja, G. Falkovich, I. Fouxon
The growth rate of small-scale density inhomogeneities (the entropy production rate) is given by the sum of the Lyapunov exponents in a random flow. We derive an analytic formula f…
