It is considered the first successful microscopic theory of superconductivity the ability of certain materials to conduct electricity with practically zero resistance.
We will begin by developing the microscopic theory which is relatively straightforward and easily tested by experiment.
Among full papers are actinide targets for the synthesis of superheavy nuclei: current priorities and future opportunities, the spontaneous fission of superheavy nuclei, odd features of some odd-odd prolate spheroidal nuclei, a microscopic theory of fission, and a free-neutron target for nuclear reaction studies.
In Sections 2.1 and 2.2, we define the order parameters and symmetry generators of the microscopic theory underlying HTSC and explain how the SO(5) symmetry arises from these structures.
Part four introduces the concept of non-commutative geometry and uses it to analyze microscopic theory. Finally, part five presents an overview of recent experimental results in the field.
In this work, we use a microscopic theory based on inhomogeneous Bogoliubov-de Gennes equations to establish how the superconducting properties of a bundle depend on the fraction of doped semiconducting nanotubes.
