Valence Bond Solids and Their Quantum Melting in Hard-Core Bosons on the Kagome Lattice
S. V. Isakov, S. Wessel, R. G. Melko +2
Using large scale quantum Monte Carlo simulations and dual vortex theory we analyze the ground state phase diagram of hard-core bosons on the kagome lattice with nearest neighbor r…

Superfluid-Insulator transitions of bosons on Kagome lattice at non-integer fillings
K. Sengupta, S. V. Isakov, Yong Baek Kim
We study the superfluid-insulator transitions of bosons on the Kagome lattice at incommensurate filling factors f=1/2 and 2/3 using a duality analysis. We find that at f=1/2 the bo…

One-dimensional itinerant ferromagnets with Heisenberg symmetry and the ferromagnetic quantum critical point
K. Sengupta, Yong Baek Kim
We study one-dimensional itinerant ferromagnets with Heisenberg symmetry near a ferromagnetic quantum critical point. It is shown that the Berry phase term arises in the effective…
