Quantum Formulation of Fractional Orbital Angular Momentum
J. B. Goette, S. Franke-Arnold, R. Zambrini +1
The quantum theory of rotation angles (S. M. Barnett and D. T. Pegg, Phys. Rev. A, 41, 3427-3425 (1990)) is generalised to non-integer values of the orbital angular momentum. This…
Oscillation patterns in negative feedback loops
Simone Pigolotti, Sandeep Krishna, Mogens H. Jensen
Organisms are equipped with regulatory systems that display a variety of dynamical behaviours ranging from simple stable steady states, to switching and multistability, to oscillat…
The Fano-Rashba effect
Llorens Serra, David Sanchez
We analyze the linear conductance of a semiconductor quantum wire containing a region where a local Rashba spin-orbit interaction is present. We show that Fano lineshapes appear in…
Multiple time-scale approach for a system of Brownian particles in a non-uniform temperature field
Cristobal Lopez, Umberto Marini Bettolo Marconi
The Smoluchowsky equation for a system of interacting Brownian particles in a temperature gradient is derived from the Kramers equation by means of a multiple time-scale method. Th…
From Coulomb blockade to the Kondo regime in a Rashba dot
Rosa Lopez, David Sanchez, Llorens Serra
We investigate the electronic transport in a quantum wire with localized Rashba interaction. The Rashba field forms quasi-bound states which couple to the continuum states with an…
Homophily, Cultural Drift and the Co-Evolution of Cultural Groups
Damon Centola, Juan Carlos Gonzalez-Avella, Victor M. Eguiluz +1
In studies of cultural differentiation, the joint mechanisms of homophily and influence have been able to explain how distinct cultural groups can form. While these mechanisms norm…
