TAP equations are repulsive

چکیده
We show that for low enough temperatures, but still above the AT line, Jacobian of TAP equations SK model has a macroscopic fraction eigenvalues outside unit interval. This provides simple explanation numerical instability fixed points, which thus occurs already in high temperature. The insight leads to some algorithmic considerations on temperature regime.

Quantum TAP equations
We derive Thouless-Anderson-Palmer (TAP) equations for quantum disordered systems. We apply them to the study of the paramagnetic and glassy phases in the quantum version of the spherical p spin-glass model. We generalize several useful quantities (complexity, threshold level, etc.) and various ideas (configurational entropy crisis, etc), that have been developed within the classical TAP approa...
متن کاملAdaptive Tap Equations
We develop a TAP mean eld approach to models with quadratic interactions which does not assume a speciic randomness of the couplings but rather adapts to the concrete data. The method is based on an extra set of mean eld equations for the Onsager correction term to the naive mean eld result. We present applications for the Hoppeld model and for a Bayesian classiier. 1.1 Introduction Mean eld (M...
متن کاملNonlinear Schrödinger Equations with Repulsive Harmonic Potential and Applications
We study the Cauchy problem for Schrödinger equations with repulsive quadratic potential and power-like nonlinearity. The local problem is well-posed in the same space as that used when a confining harmonic potential is involved. For a defocusing nonlinearity, it is globally well-posed, and a scattering theory is available, with no long range effect for any superlinear nonlinearity. When the no...
متن کاملCounterexamples of Strichartz Inequalities for Schrödinger Equations with Repulsive Potentials
where u(t, x) is the unique solution of (1.1), see [12]. Notice that estimates (1.2) describe a certain regularity for the solutions of (1.1) in terms of summability but they do not give any gain of derivatives. For this reason Strichartz estimates are very useful in order to treat the local and global well-posedness of the semilinear Schrödinger equation, but they are useless in the study of t...
