Signatures of room-temperature superconductivity emerging in two-dimensional domains within the new Bi/Pb-based ceramic cuprate superconductors at ambient pressure

Autor: Dzhumanov, S., Gulamova, D. D., Djumanov, Sh. S.

We predict the possibility of realizing room-temperature superconductivity in different 2D domains within the ceramic high-Tc cuprates at ambient pressure and experimentally confirm this prediction of 2D room-temperature superconductivity in the newl

Mass of a lattice polaron from extended Holstein model using Yukawa potential

Autor: Yavidov, B. Ya., Djumanov, Sh. S., Dzhumanov, S.

Publikováno v: Physics Letters A, vol. 374, issue 27, pp. 2772-2776 (2010)

Renormalization of the mass of an electron is studied within the framework of the Extended Holstein model at strong coupling regime and nonadiabatic limit. In order to take into account an effect of screening of an electron-phonon interaction on a po

Unusual Quasiparticle Tunneling in High-$T_c$ Cuprate Superconductors: Evidence for the BCS and Polaronic Multi-Gap Effects on Tunneling Spectra

Autor: Dzhumanov, S., Ganiev, O. K., Djumanov, Sh. S.

We propose a model of quasiparticle tunneling across the high-$T_c$ superconductor-insulator-normal metal junction based on the different mechanisms for tunneling of electrons at positive bias and dissociating polaronic Cooper pairs and large polaron

Novel Isotope Effects on the Pairing Pseudogap in High-$T_{c}$ Cuprates: Evidences for Polaronic Metal and Precursor BCS-Like Pairing of Large Polarons

Autor: Dzhumanov, S., Ganiev, O. K., Djumanov, Sh. S.

We have studied the novel isotope effects on the pairing pseudogap in underdoped and optimally doped cuprates within the large-polaron model and two non-standard BCS-like approaches. We have shown that in the intermediate-coupling regime the precurso
