On quantum critical destruction of the pseudogap phase
N. Kristoffel
Recent data on the critical events accompanying the quenching of the pseudogap (PG) phase in hole-doped cuprates are analysed. An original multiband model with the spectrum influen…
Pseudogap and the chemical potential position topology in multiband superconductors
Nikolai Kristoffel
Original definition of the pseudogap [11,12] allowes to connect it conceptually with a topological insulator. It concerns the multiband superconductivity background with variable c…
The pseudogaps in multiband electron-doped cuprate superconductivity
N. Kristoffel, P. Rubin
The pseudogap (PG) excitations in the framework of multiband superconductivity are analysed. Calculations for the doping phase diagram of electron-doped cuprate superconductors hav…
Total Internal Reflection and the Related Effects
Nikolai Kristoffel
This submission presents the English translation of the early paper by N.Kristoffel appeared in Russian in the Proceedings 0f the Tartu State University No 42 p.94-112, 1956. It re…
Analytic and geometric properties of photoinduced effects in noncentrosymmetric crystals: photovoltaic current and optical rectification
A. Pishtshev, N. Kristoffel
An original dispersion relation between the stationary coherent nonlinear optical responses by current and polarisation is obtained. The dispersion relation provides a new complime…
On the interband pairing in doped graphane
Nikolai Kristoffel, Küllike Rägo
An estimation shows that the interband pairing channel between the valence band components of doped graphane can support a superconducting transition temperature (or a contribution…
