Estimating the mass of vortices in the cuprate superconductors
Lorenz Bartosch, Leon Balents, Subir Sachdev
We explore the experimental implications of a recent theory of the quantum dynamics of vortices in superfluids proximate to Mott insulators (cond-mat/0408329 and cond-mat/0409470).…
Competing orders II: the doped quantum dimer model
Leon Balents, Lorenz Bartosch, Anton Burkov +2
We study the phases of doped spin S=1/2 quantum antiferromagnets on the square lattice, as they evolve from paramagnetic Mott insulators with valence bond solid (VBS) order at zero…
Collective fields in the functional renormalization group for fermions, Ward identities, and the exact solution of the Tomonaga-Luttinger model
Florian Schuetz, Lorenz Bartosch, Peter Kopietz
We develop a new formulation of the functional renormalization group (RG) for interacting fermions. Our approach unifies the purely fermionic formulation based on the Grassmannian…
Putting competing orders in their place near the Mott transition
Leon Balents, Lorenz Bartosch, Anton Burkov +2
We describe the localization transition of superfluids on two-dimensional lattices into commensurate Mott insulators with average particle density p/q (p, q relatively prime intege…
