Featureless and non-fractionalized Mott insulators on the honeycomb lattice at 1/2 site filling
Itamar Kimchi, S. A. Parameswaran, Ari M. Turner +2
Within the Landau paradigm, phases of matter are distinguished by spontaneous symmetry breaking. Implicit here is the assumption that a completely symmetric state exists: a paramag…
Wannier Permanent Wave Functions and Featureless Bosonic Mott Insulators on the 1/3 filled Kagome Lattice
S. A. Parameswaran, Itamar Kimchi, Ari M. Turner +2
We study Bose-Hubbard models on tight-binding, non-Bravais lattices, with a filling of one boson per unit cell -- and thus fractional site filling. At integer filling of a unit cel…
A Bionic Coulomb Phase on the Pyrochlore Lattice
V. Khemani, R. Moessner, S. A. Parameswaran +1
A class of three dimensional classical lattice systems with macroscopic ground state degeneracies, most famously the spin ice system, are known to exhibit "Coulomb" phases wherein…
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…
