Models and the limits of theory: quantum hamiltonians and the BCS model of superconductivity. The connection between formal perturbation theory and the modern theory of superconductivity is investigated. It is found that the condition for ladder dia... N Cartwright 被引量: 59发表: 1999年 Coupling...
theory perturbation theory (DFT-PT), electron–phonon coupling (EPC) can be calculated and used to predictTCwith reasonable accuracy for arbitrary materials29,30. However, the computational expense of these calculations is very high when compared to a single DFT self-consistent energy calculation, ...
Starting from the linearized BdG-equation we make the simple observation that pairing can occur between particles with total momenta different from zero, e
Heat engines convert thermal energy into mechanical work both in the classical and quantum regimes1. However, quantum theory offers genuine non-classical forms of energy, different from heat, which so far have not been exploited in cyclic engines. Here we experimentally realize a quantum many-body...
I analyze the low temperature limit of the BCS theory of s-wave single-band superconductors, when the attraction band (defined as the single-particle energy interval in which the pairing interaction is manifested) may be asymmetric with respect to the chemical potential. I discuss equilibrium ...
