Magnetic fluctuations of stripes in the high temperature cuprate superconductors.
Within the time-dependent Gutzwiller approximation for the Hubbard model we compute the magnetic fluctuations of vertical metallic stripes with parameters appropriate for La(1.875)Ba(0.125)CuO(4) (LBCO). For bond- and site-centered stripes the excitation spectra are similar, consisting of a low-energy incommensurate acoustic branch which merges into a "resonance peak" at the antiferromagnetic w...
متن کاملIslands of (In-)stability in High Temperature Superconductors
Dendritic flux penetration is a well known phenomenon in high temperature superconductors. We investigated the conditions under which this instability can be observed in different materials. We found three qualitatively different behaviors: dendrite development above a “critical field” and up to a certain temperature, above a “critical field” with no measurable temperature dependence, or no den...
متن کاملStability and Quench Protection of High-Temperature Superconductors
In the design and operation of a superconducting magnet, stability and protection are two key issues that determine the magnet's reliability and safe operation. Although the high-temperature superconductor (HTS) is considered much more stable than the low-temperature superconductor (LTS), it is susceptible to damage caused primarily by three events that can occur in large-scale "real" devices: ...
متن کاملObserving the fluctuating stripes in high-Tc superconductors
Superfluids and superconductors have been around for a long time and their explanation in terms of the Bogoliubov theory for bosons and the BCS theory for fermions belong to the highlights of twentieth century physics. However, it appears that these theories are too primitive to address the high-Tc superconductivity found in copper oxides. These electron systems seem to behave more like a dense...
