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...
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...

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...

2010/11/17
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 ...

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 ...

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...
Ross Ice Shelf in situ radio-frequency ice attenuation
Ross Ice Shelf situ radio-frequency ice attenuation

2011/1/5
We have measured the in situ average electric field attenuation length hL i for
radio-frequency signals broadcast vertically through the Ross Ice Shelf. We chose a location,
Moore Embayment, south o...
Nonlinear and chaotic ice ages: data vs speculations
