From Nested Soliton Crystals to Skyrmion Crystals in Chiral Magnets
Sven Bjarke Gudnason, Muneto Nitta
We perform an exhaustive study of the parameter space of the chiral magnetic model with a Dzyaloshinskii-Moriya interaction, an in-plane anisotropy term and an out-of-plane Zeeman…

Two-color QCD provides a unique first-principles laboratory for strongly interacting matter at finite baryon density, where a diquark condensate realizes a baryonic superfluid. We…

Tatsuhiro Hattori, Muneto Nitta, Kazuyuki Sekizawa
Pulsar glitches are believed to originate from the dynamics of quantized vortices in the neutron superfluid interior. The outer core of a neutron star hosts a spin-t…
