... semigroups came firstly from Physics. The challenge was to produce a mathematical model to describe the loss-memory evolution of a microscopic system which could be in accordance with the quantum uncertainty principle. Consequently, the roots of the theory go back to the first researches on the so-cal ...

... and W2 = j cjj cjj* wj wj*. W1, W2 are improper mixtures, found by derivation from the composite state W1+2. Let us now assume that subsystem S1 (S2) is really in one of the states vi (wj) with probabilities cii2 (cjj2). The state of the combined system can then be reconstructed, in the manner ...

... for a S = 1/2 impurity interacting with conduction electron bath (single impurity Kondo model), is controlled by fictitious chemical potential (Lagrange multiplier) of Abrikosov pseudofermions [4]. At the end of calculations this “chemical potential” λ should be put λ → −∞ to “freeze out” all unphysi ...

There is no more beautiful demonstration of this than Robert Spekkens’s “toy model” for mimicking various features of quantum mechanics [12]. In that model, the “toys” are each equipped with four p ...
