Some remarks about quantum diffusion for Hubbard models
Some exact results are given, that connect, for a general magnitude of the interaction term U , the repulsive and attractive Hubbard model, in terms of the eigenspectra and quantum diffusion properties. In particular, it is shown that, for some initial conditions, the quantum evolution cannot differenciate between the attractive and repulsive models. These results apply to both fermionic and bo...
متن کاملSome Remarks about Semiclassical Trace Invariants and Quantum Normal Forms
In this paper we explore the connection between semi-classical and quantum Birkhoff canonical forms (BCF) for Schrödinger operators. In particular we give a ”non-symbolic” operator theoretic derivation of the quantum Birkhoff canonical form and provide an explicit recipe for expressing the quantum BCF in terms of the semi-classical BCF.
متن کاملSome Remarks About Negative Efficiencies in DEA Models
Data Envelopment Analysis appeared in 1978 when the first model, known as CCR was proposed by Charnes et al. (1978). This model calculates the efficiency of productive units, known as DMUs Decision Making Units, by comparing the use of resources (inputs) and the production (outputs) obtained. This model considers Constant Returns to Scale (CRS), i.e., an increase in resources generates a propor...
متن کاملSome Remarks about Induced Qcd
Migdal and Kazakov have suggested that lattice QCD with an adjoint representation scalar in the infinite coupling limit could induce QCD. I find an exact saddlepoint of this theory for infinite N in the case of a quadratic scalar potential. I discuss some aspects of this solution and also show how the continuum D = 1 matrix model with an arbitrary potential can be reproduced through this approa...
متن کاملSome Remarks about Random Testing
The use of a pseudo-random number generator to produce test cases for software appears not to be widely used, although the method has been reported in the literature for many years [1, 2, 4]. This paper draws on experience with this technique in two areas: compilers and software components. The use of a pseudo-random number generator to produce test cases which are expected to reflect actual us...
