Two Gaps Make a High Temperature Superconductor?

open access: yes, 2008
One of the keys to the high-temperature superconductivity puzzle is the identification of the energy scales associated with the emergence of a coherent condensate of superconducting electron pairs.

High Frequency Quantum Admittance and Noise Measurement with an On-chip Resonant Circuit

open access: yes, 2012
By coupling a quantum detector, a superconductor-insulator-superconductor junction, to a Josephson junction \textit{via} a resonant circuit we probe the high frequency properties, namely the ac complex admittance and the current fluctuations of the ...

Pseudogap in high-temperature superconductors [PDF]

open access: yesPhysics-Uspekhi, 2001
This review describes the main experimental facts and a number of theoretical models concerning the pseudogap state in high - temperature superconductors. On the phase diagram of HTSC - cuprates the pseudogap state is observed in the region of current carrier concentrations less than optimal and leads to a number of anomalies of electronic properties ...

Three-band superconductivity and the order parameter that breaks time-reversal symmetry

open access: yes, 2010
We consider a model of multiband superconductivity, inspired by iron pnictides, in which three bands are connected via repulsive pair-scattering terms. Generically, three distinct superconducting states arise within such a model.

Power and temperature dependent model for high Q superconductor resonators

open access: yesAPL Quantum
Measuring the internal quality factor of coplanar waveguide superconducting resonators is an established method of determining small losses in superconducting devices. Often, resonator losses are attributed to two-level system (TLS) defects using a power

Predicting the critical superconducting temperature using the random forest, MLP neural network, M5 model tree and multivariate linear regression

open access: yesAlexandria Engineering Journal
Using a random forest regression (RFR) machine learning technique, the critical temperature (Tc) of a superconductor was predicted in the context of Industry 4.0 in this study using features derived from the material's physico-chemical properties ...

Is There a Metamaterial Route to High Temperature Superconductivity?

open access: yesAdvances in Condensed Matter Physics, 2014
Superconducting properties of a material such as electron-electron interactions and the critical temperature of superconducting transition can be expressed via the effective dielectric response function εeff (q,ω) of the material.
