Configuration-dependent diffusion can shift the kinetic transition state and barrier height of protein folding
(Natl Acad Sciences, 2007-09-11)
We show that diffusion can play an important role in protein-folding kinetics. We explicitly calculate the diffusion coefficient of protein folding in a lattice model. We found that diffusion typically is configuration- ...
From conformal invariance to quasistationary states
(Institute of Physics - IOPBristol, 2011-09)
In a conformal invariant one-dimensional stochastic model, a certain nonlocal perturbation takes the system to a new massless phase of a special kind. The ground-state of the system is an adsorptive state. Part of the ...
Critical behavior of a contact process with aperiodic transition rates
(IOP PUBLISHING LTD, 2008)
We performed Monte Carlo simulations to investigate the steady-state critical behavior of a one-dimensional contact process with an aperiodic distribution of rates of transition. As in the presence of randomness, spatial ...
Quantum state density and critical temperature in M-theory
(World Scientific Publ Co Pte Ltd, 2001-11-20)
We discuss the asymptotic properties of quantum states density for fundamental p-branes which can yield a microscopic interpretation of the thermodynamic quantities in M-theory. The matching of the BPS part of spectrum for ...
Aging and stationary properties of non-equilibrium symmetrical three-state models
(IOP PUBLISHING LTD, 2011)
We consider a non-equilibrium three-state model whose dynamics is Markovian and displays the same symmetry as the three-state Potts model, i.e. the transition rates are invariant under the cyclic permutation of the states. ...
Exact correlation functions in particle-reaction models with immobile particles
(IOP PUBLISHING LTDBRISTOL, 2012)
Exact results on particle densities as well as correlators in two models of immobile particles, containing either a single species or else two distinct species, are derived. The models evolve following a descent dynamics ...
Mean-field analysis of the majority-vote model broken-ergodicity steady state
(Institute of Physics - IOPBristol, 2012-06)
We study analytically a variant of the one-dimensional majority-vote model in which the individual retains its opinion in case there is a tie among the neighbors' opinions. The individuals are fixed at the sites of a ring ...
Localization Transition In One Dimension Using Wegner Flow Equations

Entanglement in disordered superfluids: The impact of density, interaction and harmonic confinement on the Superconductor-Insulator transition
(Elsevier B.V., 2020-05-01)
We investigate the influence of density, interaction and harmonic confinement on the superfluid to insulator transition (SIT) in disordered fermionic superfluids described by the one-dimensional Hubbard model. We quantify ...
Electronic structure and chemical bonding in the ground states of Tc(2) and Re(2)
(TAYLOR & FRANCIS LTD, 2009)
Multiconfiguration second-order perturbation theory, including relativistic effects and spin-orbit coupling, has been employed to investigate the nature of the chemical bonding in the ground state of Tc(2) and Re(2). The ...
