Impurity-induced frustration in correlated oxides

Cheng-Wei Liu, Shiu Liu, Ying-Jer Kao +2

Using the example of Zn-doped La2CuO4, we demonstrate that a spinless impurity doped into a non-frustrated antiferromagnet can induce substantial frustrating interactions among the…

Z4-U(1) crossover of the order parameter symmetry in a two-dimensional valence-bond-solid

Jie Lou, Anders W. Sandvik

We discuss ground-state projector simulations of a modified two-dimensional S=1/2 Heisenberg model in the valence bonds basis. Tuning matrix elements corresponding to the diagonal…

Groundstatable fermionic wavefunctions and their associated many-body Hamiltonians

D. Charrier, C. Chamon

In the vast majority of many-body problems, it is the kinetic energy part of the Hamiltonian that is best known microscopically, and it is the detailed form of the interactions bet…

Persistence of zero modes in a gauged Dirac model for bilayer graphene

R. Jackiw, S. -Y. Pi

A recently constructed model for low lying excitations in bilayer graphene exhibits mid-gap, zero energy modes in its Dirac-like spectrum, when a scalar order parameter takes a vor…

Edge effects in the two-dimensional spin-1/2 Heisenberg antiferromagnet

Kaj H. Hoglund, Anders W. Sandvik

We use quantum Monte Carlo simulations to study effects of free edges in the two-dimensional spin-1/2 Heisenberg antiferromagnet. We find that the magnetic response of an edge is s…

Loop updates for variational and projector quantum Monte Carlo simulations in the valence-bond basis

A. W. Sandvik, H. G. Evertz

We show how efficient loop updates, originally developed for Monte Carlo simulations of quantum spin systems at finite temperature, can be combined with a ground-state projector sc…

Theory of the Magnetic Moment in Iron Pnictides

Jiansheng Wu, Philip Phillips, A. H. Castro-Neto

We show that the combined effects of spin-orbit, monoclinic distortion, and p-d hybridization in tetrahedrally coordinated Fe in LaOFeAs invalidates the naive Hund's rule filling o…

Electron-electron interactions in graphene bilayers

S. Viola Kusminskiy, D. K. Campbell, A. H. Castro Neto

We study the effect of electron-electron interactions in the quasiparticle dispersion of a graphene bilayer within the Hartree-Fock-Thomas-Fermi theory by using a four-bands model.…

Topological order in a 3D toric code at finite temperature

Claudio Castelnovo, Claudio Chamon

We study topological order in a toric code in three spatial dimensions, or a 3+1D Z_2 gauge theory, at finite temperature. We compute exactly the topological entropy of the system,…

Localized Magnetic States in Graphene

Bruno Uchoa, Valeri N. Kotov, N. M. R. Peres +1

We examine the conditions necessary for the presence of localized magnetic moments on adatoms with inner shell electrons in graphene. We show that the low density of states at the…
