Skyrmions and Their Sizes in Helimagnets
Kwan-yuet Ho, Theodore R. Kirkpatrick, Dietrich Belitz
Skyrmion gases and lattices in helimagnets are studied, and the size of a Skyrmion in various phases is estimated. For isolated Skyrmions, the long distance tail is related to the…
Ordered Phases of Itinerant Dzyaloshinsky-Moriya Magnets and Their Electronic Properties
Kwan-yuet Ho, T. R. Kirkpatrick, Yan Sang +1
A field theory appropriate for magnets that display helical order due to the Dzyaloshinsky-Moriya mechanism, a class that includes MnSi and FeGe, is used to derive the phase diagra…
Vortex Formation in Two-Dimensional Bose Gas
Esteban Calzetta, Kwan-yuet Ho, B. L. Hu
We discuss the stability of a homogeneous two-dimensional Bose gas at finite temperature against formation of isolated vortices. We consider a patch of several healing lengths in s…
Entanglement between a Two-level System and a Quantum Harmonic Oscillator
Kwan-yuet Ho
The entanglement between a Pauli-like two-level system and a quantum harmonic oscillator enhanced by an interaction between them and a -pulse sequence is studied, with the decoh…
