Séminaire du LPTMS : Revaz Ramazashvili (LPT Toulouse)

Skyrmion-electron bound states in a Néel antiferromagnet

Revaz Ramazashvili (Laboratoire de Physique Théorique – Toulouse)

Hybrid seminar: onsite + zoom.

Meeting ID: 946 5154 7014
Passcode: N9t4y9

We show that, in a Néel antiferromagnet with a particular location
of electron band extrema, a Skyrmion and an electron form a bound
state with energy of the order of the gap $\Delta$ in the electron
spectrum. The bound state turns the Skyrmion into a charged particle,
that can be manipulated by electric field.

Date/Time : 28/06/2022 - 11:00 - 12:00
