Early time kinetics of systems with spatial symmetry breaking

Rachele Dominguez, Kipton Barros, W. Klein

In this paper we present a study of the early stages of unstable state evolution of systems with spatial symmetry changes. In contrast to the early time linear theory of unstable e…

Beyond Cahn-Hilliard-Cook: Early time behavior of symmetry breaking phase transition kinetics

Kipton Barros, Rachele Dominguez, W. Klein

We extend the early time ordering theory of Cahn, Hilliard, and Cook (CHC) so that our generalized theory applies to solid-to-solid transitions. Our theory involves spatial symmetr…

Logarithmic current fluctuations in non-equilibrium quantum spin chains

Tibor Antal, P. L. Krapivsky, A. Rákos

We study zero-temperature quantum spin chains which are characterized by a non-vanishing current. For the XX model starting from the initial state |... + + + - - - ...> we derive a…

Helix or Coil? Fate of a Melting Heteropolymer

G. Oshanin, S. Redner

We determine the probability that a partially melted heteropolymer at the melting temperature will either melt completely or return to a helix state. This system is equivalent to t…

Effect of pressure on the anomalous response functions of a confined water monolayer at low temperature

Marco G. Mazza, Kevin Stokely, H. Eugene Stanley +1

We study a coarse-grained model for a water monolayer that cannot crystallize due to the presence of confining interfaces, such as protein powders or inorganic surfaces. Using both…

Microscopic diagonal entropy and its connection to basic thermodynamic relations

Anatoli Polkovnikov

We define a diagonal entropy (d-entropy) for an arbitrary Hamiltonian system as with the sum taken over the basis of instantaneous energy states. In…

Microscopic expression for the heat in the adiabatic basis

Anatoli Polkovnikov

We derive a microscopic expression for the instantaneous diagonal elements of the density matrix in the adiabatic basis for an arbitrary time dependent process in a clo…

Scale-free networks as preasymptotic regimes of superlinear preferential attachment

Paul Krapivsky, Dmitri Krioukov

We study the following paradox associated with networks growing according to superlinear preferential attachment: superlinear preference cannot produce scale-free networks in the t…

Supplementary Information to the paper ``Breakdown of the adiabatic limit in low dimensional gapless systems''

A. Polkovnikov, V. Gritsev

Here we give detailed derivations and provide additional examples to the main paper: arXiv:0706.0212. In particular, we discuss the scaling behavior of observables like correlation…

Phase Transition with Non-Thermodynamic States in Reversible Polymerization

E. Ben-Naim, P. L. Krapivsky

We investigate a reversible polymerization process in which individual polymers aggregate and fragment at a rate proportional to their molecular weight. We find a nonequilibrium ph…

On the Brownian gas: a field theory with a Poissonian ground state

Andrea Velenich, Claudio Chamon, Leticia F. Cugliandolo +1

As a first step towards a successful field theory of Brownian particles in interaction, we study exactly the non-interacting case, its combinatorics and its non-linear time-reversa…
