Realizing colloidal artificial ice on arrays of optical traps

A Libal, C Reichhardt, CJO Reichhardt - Physical review letters, 2006 - APS
We demonstrate how a colloidal version of artificial ice can be realized on optical trap
lattices. Using numerical simulations, we show that this system obeys the ice rules and that …

Properties of ferroelectric nanodots embedded in a polarizable medium: atomistic simulations

S Prosandeev, L Bellaiche - Physical review letters, 2006 - APS
An atomistic approach is used to investigate finite-temperature properties of ferroelectric
nanodots that are embedded in a polarizable medium. Different phases are predicted …

Exactly solvable interacting spin-ice vertex model

AA Ferreira, FC Alcaraz - Physical Review E—Statistical, Nonlinear, and Soft …, 2006 - APS
A special family of solvable five-vertex model is introduced on a square lattice. In addition to
the usual nearest-neighbor interactions, the vertices defining the model also interact along …

Controlled magnetic roughness in a multilayer that has been patterned using a nanosphere array

S Langridge, LA Michez, M Ali, CH Marrows… - Physical Review B …, 2006 - APS
The micromagnetic structure of an antiferromagnetically exchange-coupled multilayer
constrained by a periodic in-plane structure has been quantified using polarized-neutron …

Triangular Ising antiferromagnet: Boundary conditions, ground state entropy, and vortices

RP Millane, RM Clare - Physical Review E—Statistical, Nonlinear, and Soft …, 2006 - APS
The ground state entropy density of the triangular Ising antiferromagnet is considered as a
function of boundary conditions on domains for which the ground states do not admit a dimer …

Dynamically reduced spaces in condensed matter physics: Quantum Hall bilayers, dimensional reduction, and magnetic spin systems

G Möller - 2006 - theses.hal.science
For a description of the low-temperature physics of condensed-matter systems, it is often
useful to work within dynamically reduced spaces. This philosophy equally applies to …

Scanning tunneling microscope measures the spin-excitation spectrum of atomic-scale magnets

M Wilson - Physics Today, 2006 - pubs.aip.org
The up-or-down spin of an electron makes it a natural qubit candidate for use, someday, in a
quantum computer. Circuit logic based on the flipping of spins would require less energy …
