Composite fermion duality for half-filled multicomponent Landau Levels
Inti Sodemann, Itamar Kimchi, Chong Wang +1
We study the interplay of particle-hole symmetry and fermion-vortex duality in multicomponent half-filled Landau levels, such as quantum Hall gallium arsenide bilayers and graphene…
Spin dynamics of counterrotating Kitaev spirals via duality
Itamar Kimchi, Radu Coldea
Incommensurate spiral order is a common occurrence in frustrated magnetic insulators. Typically, all magnetic moments rotate uniformly, through the same wavevector. However the hon…
Minimal models for topological Weyl semimetals
Timothy M. McCormick, Itamar Kimchi, Nandini Trivedi
Topological Weyl semimetals (TWS) can be classified as type-I TWS, in which the density of states vanishes at the Weyl nodes, and type-II TWS where an electron and a hole pocket me…
Incommensurate Counterrotating Magnetic Order Stabilized by Kitaev Interactions in the Layered Honeycomb -LiIrO
S. C. Williams, R. D. Johnson, F. Freund +8
The layered honeycomb magnet -LiIrO has been theoretically proposed as a candidate to display novel magnetic behaviour associated with Kitaev interactions between spin-o…
