Next Quantum Material Seminar:


Thursday 28 September, 2pm

Yoichi Yanase (Kyoto University, Japan)

“Magnetism, superconductivity and nonreciprocal responses in UTe2”


To access this seminar:

Institut Néel, Building K 1st floor, Room K223 Remy Lemaire



After the discovery of superconductivity in UTe2, clarification of correlated quantum phases including magnetic state and multiple superconducting states has been a central topic of unconventional superconductivity. We have theoretically studied UTe2 based on the microscopic and phenomenological models constructed from a first-principles calculation. I will discuss (i) Fermi surfaces, (ii) topological superconductivity, (iii) spin-triplet superconductivity arising from magnetic fluctuations, and (iv) possible nonreciprocal responses emerging from spontaneous symmetry breaking. In particular, the symmetry and topology of multiple superconducting phases of UTe2 are discussed by comparison of theories and experiments.


Next scheduled seminars are:

  • Thursday 5 October: Owen Moulding (Institut Néel)
  • Thursday 16 November: Siham Benhabib (LPS, Université Paris-Saclay)
