Speaker: Ashutosh Singh, UBC Time: 10:00-11:00am Location: BRIM 311 Abstract: I will begin with a pedagogical overview of the recently identified magnetic class known as altermagnets, placing them in context alongside conventional ferromagnets and antiferromagnets. I will then present my research on investigating chiral magnons in the metallic altermagnet CrSb. This will include a discussion of […] |

Speaker: Joseph Maciejko, University of Alberta Time: 10:00-11:00am Location: BRIM 311 Title: Topological Landau Theory Abstract: I will discuss a notion of topology “hidden” in Landau’s theory of phase transitions. When the order parameter comprises several components in the same irreducible representation of symmetry, it can possess a nontrivial topology and acquire a Berry phase under […] |

Speaker: Janez Bonča, University of Ljubljana Time: 10:00-11:00am Location: BRIM 311 Title: Signature of preformed pairs in angle-resolved two-electron coincidence photoemission Abstract: We employ density matrix renormalization group (DMRG) and variational exact diagonalization (VED) to compute single- and two-electron removal spectra of the Hubbard–Holstein model at low electron densities. By tuning electron–phonon coupling and Hubbard repulsion, […] |
