From mesoscopic magnetism to the anomalous 0.7 conductance plateau
Henrik Bruus, Vadim V. Cheianov, Karsten Flensberg
We present a simple phenomenological model which offers a unifying interpretation of the experimental observations on the 0.7 conductance anomaly of quantum point contacts. The mod…

The magnetic neutron scattering resonance of high-T_c superconductors in external magnetic fields: an SO(5) study
Niels Asger Mortensen, H. M. Ronnow, Henrik Bruus +1
The magnetic resonance at 41 meV observed in neutron scattering studies of Y Ba_2 Cu_3 O_7 holds a key position in the understanding of high-T_c superconductivity. Within the SO(5)…
