Quantum physics: United through repulsion

Electron Transport through Double Quantum Dots with Interdot Coulomb Repulsion

Electron transport through a system of two quantum dots connected in series is studied theoretically with the use of non-equilibrium Green function formalism based on the equation of motion method. Each dot is described by the one-level Anderson Hamiltonian and interdot Coulomb interactions in the form of the Hubbard-like term are taken into account. The electric current and occupation numbers ...

Transport through a double quantum dot with interdot repulsion

Abstract. We study transport through a double quantum dot with interdot hopping t, intradot repulsion U and interdot repulsion U ′, using the numerical renormalization group (NRG) method. At half-filling, the conductances in two-terminal series and four-terminal parallel configuration are calculated via two phase shifts for quasi-particles of double quantum dot connected to two noninteracting l...

Quantum Physics: A Case for Anti-Realism?

quantum physics: a case for anti-realism?

the aim of the present paper is to sbo» that anti-realism in science, 1vhich has a1;guab/y become more fashionable in recentyears, contrary to tuha: its proponents assert, cannot make use of quantum mechanics and its impressiue achievements as a frump card in justifying its claims. i will argue that scientific anti-realism far from providing scientific communiry with a progressive methodologica...

Ambiguity invokes Creativity : looking through Quantum physics

Creativity, defined as ‘the tendency to generate or recognize new ideas or alternatives and to make connections between seemingly unrelated phenomena’, is too vast a horizon to be summed up in such a simple sentence. The extreme abstractness of creativity makes it harder to quantify in its entirety. Yet, a lot of efforts have been made both by psychologists and neurobiologists to identify its s...
