EFFECTIVE INTERACTIONS DUE TO QUANTUM FLUCTUATIONSRoman
A class of quantum lattice models is considered, with Hamiltonians consisting of a classical (diagonal) part and a small oo-diagonal part (e.g. hopping terms). In some cases when the classical part has an innnite degeneracy of ground states, the quantum perturbation may stabilize some of them. The mechanism of this stabilization stems from eeective potential created by the quantum perturbation....
متن کاملdevelopment of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Effective Fermion Models in Symmetry-breaking Phase and Quantum Chromodynamics
In our lecture we discuss the fermion models with quasilocal interaction implemented by derivatives and a momentum cutoff as substitutes of QCD at low energies. They are investigated in the strong coupling regime when several coupling constants are matched to their critical values. It is found that around polycritical points there appear a number of resonances with the same quantum numbers. Res...
متن کاملInteractions and broken time-reversal symmetry in chaotic quantum dots
When treating interactions in quantum dots within a random-phase-approximation sRPAd-like approach, time-reversal symmetry plays an important role as higher-order terms—the Cooper series—need to be included when this symmetry is present. Here we consider model quantum dots in a magnetic field weak enough to leave the dynamics of the dot chaotic, but strong enough to break time-reversal symmetry...
متن کاملFrom Computability to Simulability
We are intelligent, so we are conscient. We are in evolution, so we construct. We are not alone, so we have to contribute. Simulation relates function to structure: faith = (intuition, inspiration, imagination) and intelligence = (adaptability, consciousness, intention) are complementary one to another. Intelligence and Faith can converge together to integration, or can destroy each other if no...
