Direct evidence of spatial stability of Bose-Einstein condensate of magnons
I. V. Borisenko, B. Divinskiy, V. E. Demidov +4
Bose-Einstein condensation of quasi-equilibrium magnons is one of few macroscopic quantum phenomena observed at room temperature. Since its discovery, it became an object of intens…
Topological defects in helical magnets
T. Nattermann, V. L. Pokrovsky
Helical magnets which violated space inversion symmetry have rather peculiar topological defects. In isotropic helical magnets with exchange and Dzyaloshinskii-Moriya interactions…
Long-wave magnons in a ferromagnetic film
Gang Li, Chen Sun, Thomas Nattermann +1
An asymptotically exact theory of spectrum and transverse distribution of magnetization in long-wave magnons is presented. It is based on exact analytical solution of linearized La…
Vector Chiral Phases in the Frustrated 2D XY Model and Quantum Spin Chains
H. Schenck, V. L. Pokrovsky, T. Nattermann
The phase diagram of the frustrated 2D classical and 1D quantum XY models is calculated analytically. Four transitions are found: the vortex unbinding transitions triggered by stro…
Vortex Wall Dynamics and Pinning in Helical Magnets
Bahman Roostaei
Domain walls formed by one dimensional array of vortex lines have been recently predicted to exist in disordered helical magnets and multiferroics. These systems are on one hand an…
Pre-melting of crossing vortex lattices
S. Butsch, E. Zeldov, T. Nattermann
The pre-melting of high vortex density planes observed recently in layered superconductors in tilted magnetic field is explained theoretically. Based on the structural information…
