Symmetry and Complexity in Condensed Matter: Two Nonsymmorphic Tales
(Aline Ramires, TU Wien)
Nonsymmorphic symmetries have been in the spotlight in condensed matter physics since the advent of topological band theory and, most recently, have been highlighted in the context of altermagnetism. In this talk, I will introduce nonsymmorphic symmetries and show how these necessarily introduce complexity in condensed matter systems. I will also discuss two scenarios in which the presence of nonsymmorphic symmetries can lead to novel physical phenomena. The first example concerns the identification of a new mechanism for the multifunctionalization of materials, potentially involving superconductivity. The second example concerns a new scenario for one of the longest-standing problems in condensed matter: the origin of the mysterious pseudogap phase in high-temperature superconductors. These examples highlight important consequences of this special type of symmetry, also in correlated electronic matter.
