4pm - 5pm
Abstract: Do quantum particles in mixed orbital bands (such as p and d) organize themselves coherently at low temperature limit into topological states of matter by interaction? I will narrate, through simple and powerful models from cold atoms in optical lattices to electrons in LaAlO3/SrTiO3 oxide interfaces, how one may encounter exotic many-body states like quantum Hall-like insulators without Landau level, topological superconductivity/superfluidity by only s-wave scattering, and orbital-induced magnetic Skyrmions as ground state.
