Superexchange and superconductivity: A possible correlation

Is room-temperature superconductivity with phonons possible?

By recognizing the vital importance of two-hole Cooper pairs (CPs) in addition to the usual two-electron ones in a strongly-interacting many-electron system, the concept of CPs was re-examined with striking conclusions: namely, they are gapped and linearly-dispersive resonances with a finite lifetime—but provided the ideal-gas Fermi sea is replaced by a BCS-correlated unperturbed ground-state “...

Possible origins of high-Tc superconductivity.

Correlation-induced superconductivity dynamically stabilized and enhanced by laser irradiation

Studies on out-of-equilibrium dynamics have paved a way to realize a new state of matter. Superconductor-like properties above room temperatures recently suggested to be in copper oxides achieved by selectively exciting vibrational phonon modes by laser have inspired studies on an alternative and general strategy to be pursued for high-temperature superconductivity. We show that the superconduc...

Superconductivity in an electron band just above the Fermi level: possible route to BCS-BEC superconductivity

Conventional superconductivity follows Bardeen-Cooper-Schrieffer(BCS) theory of electrons-pairing in momentum-space, while superfluidity is the Bose-Einstein condensation(BEC) of atoms paired in real-space. These properties of solid metals and ultra-cold gases, respectively, are connected by the BCS-BEC crossover. Here we investigate the band dispersions in FeTe(0.6)Se(0.4)(Tc = 14.5 K ~ 1.2 me...

Correlation between Ultrafiltration Coefficient and Effective Lymphatic Absorption Rate in Continuous Ambulatory Peritoneal Dialysis Patients: A Possible Paradigm Shift

Background: The relative contribution of transcapillary water movement and lymphatic reabsorption in peritoneal dialysis (PD) is a critical issue, particularly in patients with ultrafiltration failure (UFF). Based on routine results obtained from the PD Adequest 2.0 software, the present study aimed to re-evaluate the separate effects of transcapillary water movement and lymphatic reabsorption ...
