Two-step melting of three-sublattice order in easy-axis triangular lattice antiferromagnets
Dariush Heidarian, Kedar Damle
We consider triangular lattice Heisenberg antiferromagnets with a strong single-ion anisotropy that dominates over the nearest-neighbour antiferromagnetic exchange . I…
Electric field control of spins in bilayer graphene: Local moment formation and local moment interactions
Matthew Killi, Dariush Heidarian, Arun Paramekanti
We study local moment formation for adatoms on bilayer graphene (BLG) within a mean-field theory of the Anderson impurity model. The wavefunctions of the BLG electrons induce stron…
Supersolidity in the triangular lattice spin-1/2 XXZ model: A variational perspective
Dariush Heidarian, Arun Paramekanti
We study the spin-1/2 XXZ model on the triangular lattice with a nearest neighbor antiferromagnetic Ising coupling and unfrustrated () or frustrated (…
From magnetism to one-dimensional spin liquid in the anisotropic triangular lattice
Dariush Heidarian, Federico Becca, Sandro Sorella
We investigate the anisotropic triangular lattice that interpolates from decoupled one-dimensional chains to the isotropic triangular lattice and has been suggested to be relevant…
Finite Drude weight for 1D low temperature conductors
Dariush Heidarian, Sandro Sorella
We apply well established finite temperature Quantum Monte Carlo techniques to one dimensional Bose systems with soft and hardcore constraint, as well as to spinless fermion system…
Resonant Pair Exchange and Percolation in the Disordered Hubbard Model
Dariush Heidarian, Mustansir Barma, Nandini Trivedi
We show that the effect of disorder on a Mott-Hubbard insulator of interacting electrons produces a quantum phase transition from an antiferromagnetic to a paramagnetic phase gover…
