1 | Symko, Orest George | Background signals in SQUID magnetometers | Since a SQUID magnetometer is an extremely sensitive device capable of detecting minute magnetic flux changes in a sample, it will also detect unwanted signals from materials near the magnetometer. The presence of temperature dependent "background signals" limits the accuracy of measurements of ... | SQUID magnetometer; Background signals | 1974 | |
2 | Mattis, Daniel C. | New wave-operator identity applied to the study of persistent currents in 1D | We show that a large class of backward-scattering matrix elements involving Δk ~ + 2k F vanish for fermions interacting with two-body attractive forces in one dimension. (These same matrix elements are finite for noninteracting particles and infinite for particles interacting with two-body repulsiv... | Persistent current; Supercurrents | 1974 |
