A thermodynamically interactive ice shelf cavity
parameterization is coupled to the Regional Ocean Model
System (ROMS) and is applied to the Southern Ocean domain with enhanced resolution in the Wed...
Antarctica’s Ross Sea is one of the few polar regions where summer sea-ice coverage has increased during the last few decades, bucking a global trend of drastic declines in summer sea ice across the A...

A research team has developed a significantly more cost-effective and easily accessible process for testing ice adhesion with different materials. Development of this process and other findings in fun...
Debye-Hückel theory for spin ice at low temperature
Debye-Hückel theory spin ice low temperature
2011/8/18
Abstract: At low temperatures, spin ice is populated by a finite density of magnetic monopoles-pointlike topological defects with a mutual magnetic Coulomb interaction. We discuss the properties of th...

vdW-DF small water clusters ice Ih
2011/9/15
We present results for a density functional theory study of small water clusters and hexagonal ice Ih, using the van der Waals density functional (vdW-DF). In particular, we examine energetic,structur...

High-Pressures Ground-State Structures Ice
2011/9/13
Ab initio random structure searching based on density functional theory is used to determine the ground-state structures of ice at high pressures. Including estimates of lattice zero-point energies,ic...
We examine the onset of classical topological order in a nearest-neighbor kagome ice model. Using Monte Carlo simulations, we characterize the topological sectors of the groundstate using a non-local ...
Dynamic susceptibility of a spin-ice near the critical point
Dynamic susceptibility spin-ice near the critical point
2010/11/23
We consider spin ice magnets (primarily, Dy2Ti2O7) in the vicinity of their critical point on the (H, T )plane. We find that the longitudinal susceptibility diverges at the critical point, leading to ...
Dirac Strings and Magnetic Monopoles in Spin Ice Dy2Ti2O7
Dirac Strings Magnetic Spin Ice Dy2Ti2O7
2010/11/18
While sources of magnetic fields — magnetic monopoles — have so far proven elusive as
elementary particles, several scenarios have been proposed recently in condensed matter physics
of emergent quas...
