On the Exponential Decay of Correlation Functions*
We use the properties of subharmonic functions to prove the following results, First, for any lattice system with finite-range forces there is a gap in the spectrum of the transfer matrix, which persists in the thermodynamic limit, if the fugacity z lies in a region E of the complex plane that contains the origin and is free of zeros of the grand partition function (with periodic boundary condi...
متن کاملRigorous description of exchange-correlation energy of many-electron systems.
With the eigenfunctional theory, we study a general interacting electron system, and give a rigorous expression of its ground state energy, which is composed of two parts: one part is contributed by the non-interacting electrons, and the other one is represented by the correlation functions that are controlled by the electron correlation. Moreover, according to the rigorous expression of the gr...
متن کاملCorrelation functions and fidelity decay in chaotic systems
In this work several aspects of quantum chaos are studied in the time domain. The wave equation for flat microwave cavities is equivalent to the Schrödinger equation in quantum mechanics. Therefore microwave measurements provide an experimental approach to quantum chaos. The experiments are described in terms of scattering theory, to take the coupling of the antennas to the system as well as th...
متن کاملExponential Decay of Quantum Wave Functions
I’ve no doubt that for ODEs, the questions and techniques for exponential decay of solutions go back a long way, maybe even to the nineteenth century. For one body systems with decaying potential, I think they are at least in Titchmarsh’s book. For ODEs with explicit polynomially growing potentials there are precise asymptotics going back to the at least the middle of the twentieth century. My ...
متن کاملCorrelation at Low Temperature: I. Exponential Decay
The present paper generalizes the analysis [18, 2] of the correlations for a lattice system of real-valued spins at low temperature. The Gibbs measure is assumed to be generated by a fairly general pair potential (Hamiltonian function). The novelty, as compared to [18, 2], is that the single-site (self-) energies of the spins are not required to have only a single local minimum and no other ext...
