Heat transport and spin-charge separation in the normal state of high temperature superconductors
, 2000 Hill et al. have recently measured both the thermal and charge conductivities in the normal state of a high temperature superconductor. Based on the vanishing of the Wiedemann-Franz ratio in the extrapolated zero temperature limit, they conclude that the

physica status solidi (a), Volume 216, Issue 23, December 2019., 2019 Growth of transition metal oxides on oxidized silicon substrates opens the possibility for new device structures. Reactive sputtering of the oxide deteriorates the Si/SiO2 surface passivation. Decoupling the oxidation step from the sputter deposition of the metal can alleviate this difficulty and results in superior Si/SiO2/TMO junctions.

Destruction of the Kondo effect in a multi-channel Bose-Fermi Kondo model
, 2004 We consider the SU(N) x SU(kappa N) generalization of the spin-isotropic Bose-Fermi Kondo model in the limit of large N. There are three fixed points corresponding to a multi-channel non-Fermi liquid phase, a local spin-liquid phase, and a Kondo ...

High Voltage, Volume 4, Issue 2, Page 122-129, June 2019., 2019 Mechanical circuit breakers (MCBs) are the limiting component for current injection HVDC circuit breakers. Improving their interruption performance reduces requirements for capacitance and inductance needed in the injection circuit and thus space use and costs.

Quantum Criticality and the Kondo Lattice
, 2010 Quantum phase transitions (QPTs) arise as a result of competing interactions in a quantum many-body system. Kondo lattice models, containing a lattice of localized magnetic moments and a band of conduction electrons, naturally feature such competing ...
