The Landau level: Half-full or half-empty?
Ganpathy Murthy, R. Shankar
We show here that an extension of the Hamiltonian theory developed by us over the years furnishes a composite fermion (CF) description of the state that is particle…
Hamiltonian theory of fractionally filled Chern bands
Ganpathy Murthy, R. Shankar
There is convincing numerical evidence that fractional quantum Hall (FQH)-like ground states arise in fractionally filled Chern bands (FCB). Here we show that the Hamiltonian theor…
Dipolar bogolons: from superfluids to Pfaffians
S. A. Parameswaran, S. A. Kivelson, R. Shankar +2
We study the structure of Bogoliubov quasiparticles, 'bogolons,' the fermionic excitations of paired superfluids that arise from fermion (BCS) pairing, including neutral superfluid…
The last word in strong correlations
R. Shankar
In the Fractional Quantum Hall Effect (FQHE), in the noninteracting limit, only a fraction of the Lowest Landau Level (LLL) is occupied, producing a huge degeneracy. Interactio…
Quarter-Filled Honeycomb Lattice with a Quantized Hall Conductance
Ganpathy Murthy, Efrat Shimshoni, R. Shankar +1
We study a generic two-dimensional hopping model on a honeycomb lattice with strong spin-orbit coupling, without the requirement that the half-filled lattice be a Topological Insul…
Composite Fermions for Fractionally Filled Chern Bands
Ganpathy Murthy, R. Shankar
We address the question of whether fractionally filled bands with a nontrivial Chern index in zero external field could also exhibit a Fractional Quantum Hall Effect (FQHE). Numeri…
