As first demonstrated by the characterization of the quantum Hall effect by the Chern number, topology provides a guiding principle to realize the robust properties of condensed-matter systems immune to the existence of disorder. The bulk–boundary corre
This highly non-trivial functional form of the potential is found via the Bohr–Sommerfeld quantization formula using the full- °edged Riemann–von Mangoldt counting formula for the number N(E) of zeroes in the critical strip with imaginary part greater than 0 and less than or equal to E....
1.A method of generating a second set of equations requiring reduced numbers of computations from a first set of general equations, wherein each general equation defines a coefficient in terms of a set of samples and a plurality of functions having respective values dependent upon each sample, s...
Bohrmade use of the concept of quantization and proposes his theory. According to his theory, the electron revolves around the nucleus without losing energy. It gains energy when electrons move from a lower energy state to a higher and it loses energy when electrons move from a higher state t...
