Role of fluctuations for density-wave instabilities: Failure of the mean-field description
Mareike Hoyer, Jörg Schmalian
Density-wave instabilities have been observed and studied in a multitude of materials. Most recently, in the context of unconventional superconductors like the iron-based supercond…

Short-distance breakdown of the Higgs mechanism and the robustness of the BCS theory for charged superconductors
Sonja Fischer, Matthias Hecker, Mareike Hoyer +1
Through the Higgs mechanism, the long-range Coulomb interaction eliminates the low-energy Goldstone phase mode in superconductors and transfers spectral weight all the way up to th…

Disorder-promoted -symmetric magnetic order in iron-based superconductors
Mareike Hoyer, Rafael M. Fernandes, Alex Levchenko +1
In most iron-based superconductors, the transition to the magnetically ordered state is closely linked to a lowering of structural symmetry from tetragonal () to orthorhombi…
