The Antillese in France: Trends and prospects

The cultural drives in the Antillese population in continental France have switched, in step with migration dynamics, in direction and target: they focus less than in the past on the future of the ‘native lands’ and more on improved integration in the host country. But in such a situation, facing racism, Antillese peoples in France are paradoxically reduced to emphasizing their collective identity, notably through associations, to obtain recognition from the host society’s institutions and achieve social advancement within that society. A recognition of the diversity and complexity of the cultural dynamics in question should lead to break with any essentialist thinking and, then, to reappraise many of the ideas that are at the heart of the discussions inspired by those dynamics, notably the idea of diaspora.

Aging of spherical spin glasses

Sompolinski and Zippelius (1981) propose the study of dynamical systems whose invariant measures are the Gibbs measures for (hard to analyze) statistical physics models of interest. In the course of doing so, physicists often report of an “aging” phenomenon. For example, aging is expected to happen for the Sherrington-Kirkpatrick model, a disordered mean-field model with a very complex phase transition in equilibrium at low temperature. We shall study the Langevin dynamics for a simplified spherical version of this model. The induced rotational symmetry of the spherical model reduces the dynamics in question to an N-dimensional coupled system of Ornstein-Uhlenbeck processes whose random drift parameters are the eigenvalues of certain random matrices. We obtain the limiting dynamics for N approaching infinity and by analyzing its long time behavior, explain what is aging (mathematically speaking), what causes this phenomenon, and what is its relationship with the phase transition of the corresponding equilibrium invariant measures.

Comment on “Nonadiabatic dynamics of atoms in nonuniform magnetic fields”

The development of an accurate method for solving systems of differential equations and the prediction of an unusual nonadiabatic regime of neutral atoms in magnetic traps as claimed by Yukalov [Phys. Rev. A 56, 5004 (1997)] are questioned. A defect arises from his method for the exact solution of differential equations, claiming generality at the basis of all his calculations. As shown in this Comment, the method is exact only for a very narrow class of equations. This class is determined and found to be quite inadequate for the physical conditions of the nonadiabatic dynamics in question.

Mechanism of particle-flux separation and generation of the dynamical gauge field in the Chern-Simons theory with fermions

We study the nonperturbative aspects of the Chern-Simons (CS) gauge theory coupled with fermions by using spatial-lattice regularization. This system is relevant to (i) the composite-fermion approach to the fractional quantum Hall effect, and (ii) the fermionic description of the s = 1 2 quantum XY spin model. It is expected that there are (at least) two phases in this system: One is the constrained phase in which the CS constraint is respected by quasiparticles, so certain amount of gauge fluxes are to be attached to each fermion. The other is the dynamical phase in which the CS constraint is irrelevant to the quasiparticles, and a dynamical gauge field is generated as an independent field. We call this phenomenon of irrelevance of the CS constraint to the quasiparticles a particle-flux separation (PFS), since particles and fluxes do not constrain each other. This PFS is characterized through the dynamics of an auxiliary gauge field that glues particles and CS fluxes, and bears very close resemblance to the phenomenon of charge-spin separation in the strongly correlated electron system for high- T c, superconductivity. We show that there is a confinement-deconfinement (CD) phase transition in the gauge dynamics in question, which is of the same type as the Kosterlitz-Thouless (KT) transition of the classical XY model in two dimensions. The critical temperature T CD is calculable and dependent the CS coefficient and the density of fermions. The constrained phase is identified with the confinement phase of gauge dynamics at T > T CD, while the dynamical phase with PFS is identified with the deconfinement phase at T < T CD. This result is applicable to the system of electrons in a uniform magnetic field at Landau filling factor v = 1 2 . That is, there appears a dynamical gauge field that interacts weakly with the so-called composite fermions. This justifies several existing analyses based on perturbation theory, which conclude non-Fermi-liquid-like behavior of the fermionic quasiparticles.

Algebraic Riccati equations with non-smoothing observation arising in hyperbolic and Euler-Bernoulli boundary control problems

This paper considers the optimal quadratic cost problem (regulator problem) for a class of abstract differential equations with unbounded operators which, under the same unified framework, model in particular «concrete» boundary control problems for partial differential equations defined on a bounded open domain of any dimension, including: second order hyperbolic scalar equations with control in the Dirichlet or in the Neumann boundary conditions; first order hyperbolic systems with boundary control; and Euler-Bernoulli (plate) equations with (for instance) control(s) in the Dirichlet and/or Neumann boundary conditions. The observation operator in the quadratic cost functional is assumed to be non-smoothing (in particular, it may be the identity operator), a case which introduces technical difficulties due to the low regularity of the solutions. The paper studies existence and uniqueness of the resulting algebraic (operator) Riccati equation, as well as the relationship between exact controllability and the property that the Riccati operator be an isomorphism, a distinctive feature of the dynamics in question (emphatically not true for, say, parabolic boundary control problems). This isomorphism allows one to introduce a «dual» Riccati equation, corresponding to a «dual» optimal control problem. Properties between the original and the «dual» problem are also investigated.

Notes on a Socio-Historical Perspective of Family Therapy

The social and political implications of family therapy are explored by examining the link between social and family dynamics. Issues of a) parental authority and its relationship to work, and b) the myth of separate public and private spheres can serve to inform family therapists of the interface between the social world and the family. The implications for conducting a family therapy uninformed of the social dynamics in question are discussed.
