Low-energy theory of a two-dimensional itinerant chiral magnet
Armin Rahmani, Rodrigo A. Muniz, Ivar Martin
Effective actions, such as nonlinear sigma models, are important tools in studying low-energy fluctuations of magnetically ordered states. Here we derive an effective action for th…
Generalized spin-wave theory: application to the bilinear-biquadratic model
Rodrigo A. Muniz, Yasuyuki Kato, Cristian D. Batista
We present a generalized spin-wave theory (GSWT) for treating spin Hamiltonians of arbitrary spin . The generalization consists of an extension of the traditional spin-wave theo…
Anyons in integer quantum Hall magnets
Armin Rahmani, Rodrigo A. Muniz, Ivar Martin
Strongly correlated fractional quantum Hall liquids support fractional excitations, which can be understood in terms of adiabatic flux insertion arguments. A second route to fracti…
