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

The effect of annealing at room temperature on the fluctuation conductivity (FLC) $\sigma^\prime(T)$ and pseudogap (PG) $\Delta^*(T)$ in the basal ab plane of $ReBa_2Cu_3O_{7-\delta}$ (Re = Ho) single crystals with a lack of oxygen has been studied.

A consistent microscopic theory of pseudogap phenomena and novel Bose-liquid superconductivity (superfluidity) is presented, based on the fact that in high-$T_c$ cuprates and related systems the energy $\varepsilon_A$ of the effective attraction betw

The criteria for bosonization of Cooper pairs and novel Bose-liquid superconductivity and superfluidity in high-$T_c$ cuprates and other pseudogap matters are formulated by using the uncertainty principle and the boson mean field theory. We argue tha

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

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

We propose a unified approach for describing the carrier localization, metal-insulator transitions (MITs) and stripe formation in high-$T_c$ cuprates. The ground-state energy of a carrier interacting with a defect and with lattice vibrations is calcu

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
