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…
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…
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…
Extreme value statistics of work done in stretching a polymer in a gradient flow
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…
Irreversible Monte Carlo Algorithms for Efficient Sampling
Konstantin S. Turitsyn, Michael Chertkov, Marija Vucelja
Equilibrium systems evolve according to Detailed Balance (DB). This principe guided development of the Monte-Carlo sampling techniques, of which Metropolis-Hastings (MH) algorithm…
