Screening properties and phase transitions in unconventional plasmas for Ising-type quantum Hall states
Egil Herland, Egor Babaev, Parsa Bonderson +3
Utilizing large-scale Monte-Carlo simulations, we investigate an unconventional two-component classical plasma in two dimensions which controls the behavior of the norms and overla…
Weakly-Coupled non-Abelian Anyons in Three Dimensions
Michael Freedman, Matthew B. Hastings, Chetan Nayak +1
We introduce a Hamiltonian coupling Majorana fermion degrees of freedom to a quantum dimer model. We argue that, in three dimensions, this model has deconfined quasiparticles suppo…
Majorana Zero Modes in 1D Quantum Wires Without Long-Ranged Superconducting Order
Lukasz Fidkowski, Roman M. Lutchyn, Chetan Nayak +1
We show that long-ranged superconducting order is not necessary to guarantee the existence of Majorana fermion zero modes at the ends of a quantum wire. We formulate a concrete mod…
SU(2) Slave Fermion Solution of the Kitaev Honeycomb Lattice Model
F. J. Burnell, Chetan Nayak
We apply the SU(2) slave fermion formalism to the Kitaev honeycomb lattice model. We show that both the Toric Code phase (the A phase) and the gapless phase of this model (the B ph…
Effective Field Theory of Fractional Quantized Hall Nematics
Michael Mulligan, Chetan Nayak, Shamit Kachru
We present a Landau-Ginzburg theory for a fractional quantized Hall nematic state and the transition to it from an isotropic fractional quantum Hall state. This justifies Lifshitz-…
