Spin glass state in layered compound MnSb2Te4
Hao Li, Yaoxin Li, Yu-Kun Lian +5
As a sister compound and isostructural of MnBi2Te4, the high quality MnSb2Te4 single crystals are grown via solid-state reaction where prolonged annealing and narrow temperature wi…
Skyrmion zoo in graphene at charge neutrality in a strong magnetic field
Jonathan Atteia, Yunlong Lian, Mark Oliver Goerbig
As a consequence of the approximate spin-valley symmetry in graphene, the ground state of electrons in graphene at charge neutrality is a particular SU(4) quantum-Hall ferromagnet…
Spin-valley skyrmions in graphene at filling factor
Yunlong Lian, Mark O. Goerbig
We model quantum Hall skyrmions in graphene monolayer at quarter filling by a theory of CP3 fields and study the energy minimizing skyrmions in presence of valley pseudospin anisot…
SU(4) Skyrmions in the Quantum Hall State of Graphene
Yunlong Lian, Achim Rosch, Mark O. Goerbig
We explore different skyrmion types in the lowest Landau level of graphene at a filling factor . In addition to the formation of spin and valley pseudospin skyrmions, we s…
