Scaling law of diffusivity generated by a noisy telegraph signal with fractal intermittency
Paradisi, P.; Allegrini, P. (2015-12-31)
; Allegrini, P. (2015-12-31)
In many complex systems the non-linear cooperative dynamics determine the emergence of self-organized, metastable, structures that are associated with a birth-death process of cooperation. This is found to be described by ...
Velocity and energy distributions in microcanonical ensembles of hard spheres
Scalas, E.; Gabriel, A.T.; Martin, E.; Germano, G. (2015-12-31)
; Gabriel, A.T.; Martin, E.; Germano, G. (2015-12-31)
In a microcanonical ensemble (constant NVE, hard reflecting walls) and in a molecular dynamics ensemble (constant NVEPG, periodic boundary conditions) with a number N of smooth elastic hard spheres in a d-dimensional volume ...
A renewal model for the emergence of anomalous solute crowding in liposomes
Paradisi, P.; Allegrini, P.; Chiarugi, D. (2015-12-31)
; Allegrini, P.; Chiarugi, D. (2015-12-31)
A fundamental evolutionary step in the onset of living cells is thought to be the spontaneous formation of lipid vesicles (liposomes) in the pre-biotic mixture. Even though it is well known that hydrophobic forces drive ...
Microscopic conductivity of lattice fermions at equilibrium. I. Non-interacting particles
Bru, J.-B.; de Siqueira Pedra, W.; Hertling, C. (2015-12-31)
; de Siqueira Pedra, W.; Hertling, C. (2015-12-31)
We consider free lattice fermions subjected to a static bounded potential and a timeand space-dependent electric field. For any bounded convex region R ⊂ ℠(d (d ≥ 1) of space, electric fields ε within R drive currents. ...
Characterization of the Quasi-Stationary State of an Impurity Driven by Monochromatic Light II: Microscopic Foundations
Bru, J.-B.; de Siqueira Pedra, W. (2015-12-31)
; de Siqueira Pedra, W. (2015-12-31)
From quantum mechanical first principles only, we rigorously study the time-evolution of a N-level atom (impurity) interacting with an external monochromatic light source within an infinite system of free electrons at ...
D-Wave pairing driven by bipolaric modes related to giant electron-phonon anomalies in high-Tc superconductors
Bru, J.-B.; de Pasquale, A.D.; de Siqueira Pedra, W. (2015-12-31)
; de Pasquale, A.D.; de Siqueira Pedra, W. (2015-12-31)
Taking into account microscopic properties of most usual high-Tc superconductors, like cuprates, we define a class of microscopic model Hamiltonians for two fermions (electrons or holes) and one boson (bipolaron) on the ...
AC-Conductivity Measure from Heat Production of Free Fermions in Disordered Media
Bru, J.-B.; de Siqueira Pedra, W.; Hertling, C. (2015-12-31)
; de Siqueira Pedra, W.; Hertling, C. (2015-12-31)
We extend (Bru et al. in J Math Phys 56:051901-1-51, 2015) in order to study the linear response of free fermions on the lattice within a (independently and identically distributed) random potential to a macroscopic electric ...
Microscopic Conductivity of Lattice Fermions at Equilibrium. Part II: Interacting Particles
Bru, J.-B.; de Siqueira Pedra, W. (2015-12-31)
; de Siqueira Pedra, W. (2015-12-31)
We apply Lieb–Robinson bounds for multi-commutators we recently derived (Bru and de Siqueira Pedra, Lieb–Robinson bounds for multi-commutators and applications to response theory, 2015) to study the (possibly non-linear) ...
From the 2nd Law of Thermodynamics to AC–Conductivity Measures of Interacting Fermions in Disordered Media
Bru, J.-B.; de Siqueira Pedra, W. (2015-05-20)
; de Siqueira Pedra, W. (2015-05-20)
We study the dynamics of interacting lattice fermions with random hopping amplitudes and random static potentials, in presence of time-dependent electromagnetic fields. The interparticle interaction is short-range and ...
