### BCS theory of superconductivity: it is time to question its validity

- Physics
- 2009

The time-tested Bardeen–Cooper–Schrieffer (BCS) theory of superconductivity is generally accepted to be the correct theory of conventional superconductivity by physicists and, by extension, by the…

### Ubiquity of Superconducting Domes in the Bardeen-Cooper-Schrieffer Theory with Finite-Range Potentials.

- PhysicsPhysical review letters
- 2019

It is demonstrated that any well-defined nonlocal potential leads to a "superconducting dome," i.e., a nonmonotonic T_{c}(n) exhibiting a maximum value at finite doping and going to zero for large n, which proves that, contrary to conventional wisdom, the presence of a superconducting Dome is not necessarily an indication of competing orders, nor of exotic superconductivity.

### Breakdown of the Migdal-Eliashberg theory and a theory of lattice-fermionic superfluidity

- PhysicsPhysical Review B
- 2022

We show that the Migdal-Eliashberg theory loses validity at a ﬁnite value λ c of the electron-phonon coupling λ regardless of the underlying model Hamiltonian. The value of λ c is approximately…

### Ab initiotheory of superconductivity in a magnetic field. II. Numerical solution

- Physics
- 2015

We numerically investigate the Spin Density Functional theory for superconductors (SpinSCDFT) and the approximated exchange-correlation functional, derived and presented in the preceding paper I. As…

### Room Temperature Superconductivity: the Roles of Theory and Materials Design

- Physics
- 2022

For half a century after the discovery of superconductivity, materials exploration for better superconductors proceeded without knowledge of the underlying mechanism. The 1957 BCS theory cleared that…

### Electron-phonon Coupling in Quasi-Two-Dimensional Correlated Systems

- Physics
- 2010

Over the past 20 years a great deal of progress has been made towards understanding the physics of the high-temperature (high-Tc) cuprate superconductors. Much of the lowenergy physics of these…

### Revised Tolmachev-Morel-Anderson pseudopotential for layered conventional superconductors with nonlocal Coulomb interaction

- Physics
- 2022

We study the eﬀects of static nonlocal Coulomb interactions in layered conventional superconductors and show that they generically suppress superconductivity and reduce the critical temperature.…

### CALCULATION OF THE SUPERCONDUCTING STATE PARAMETERS WITH RETARDED ELECTRON- PHONON INTERACTION

- Physics
- 1962

The energy gap and other parameters of the superconducting state are calculated from the Bardeen-CooperSchrieffer theory in Gor'kov-Eliashberg form, using a realistic retarded electron-electron…

### Theory of superconductivity

- Physics
- 1957

A theory of superconductivity is presented, based on the fact that the interaction between electrons resulting from virtual exchange of phonons is attractive when the energy difference between the…

### Theory of superconducting transition temperature, pair susceptibility, and coherence length

- Physics
- 1980

As the superconducting transition temperature Tc is approached from above, Cooper pair fluctuations grow in amplitude, and the pair susceptibility (which measures the tendency of pairs to form in…

### QUASI-PARTICLES AND GAUGE INVARIANCE IN THE THEORY OF SUPERCONDUCTIVITY

- Physics
- 1960

Ideas and techniques known in quantum electrodynamics have been applied to the Bardeen-Cooper-Schrieffer theoryof superconductivity. In an approximation which corresponds to a generalization of the…

We present a new aspect of superconductivity in A-15 compounds which is able to explain their exceptional role among the highTc superconductors. The basic idea is that a strong energy dependence of…

### On dirty superconductors.
