Topologically protected quantum bits from Josephson junction arrays
L. B. Ioffe, M. V. Feigel'man, A. Ioselevich +3
All physical implementations of quantum bits (qubits), carrying the information and computation in a putative quantum computer, have to meet the conflicting requirements of environ…
Analytical and numerical study of hardcore bosons in two dimensions
K. Bernardet, G. G. Batrouni, J. -L. Meunier +3
We study various properties of bosons in two dimensions interacting only via onsite hardcore repulsion. In particular, we use the lattice spin-wave approximation to calculate the g…
Accessing the dynamics of large many-particle systems using Stochastic Series Expansion
A. Dorneich, M. Troyer
The Stochastic Series Expansion method (SSE) is a Quantum Monte Carlo (QMC) technique working directly in the imaginary time continuum and thus avoiding "Trotter discretization" er…
Nature of the quantum phase transitions in the two-dimensional hardcore boson model
F. Hebert, G. G. Batrouni, R. T. Scalettar +3
We use two Quantum Monte Carlo algorithms to map out the phase diagram of the two-dimensional hardcore boson Hubbard model with near () and next near () neighbor repulsio…
