A demonstration of AZURITE: Backtracking tool for programmers [PDF]

open access: yes2014 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC), 2014
Programmers often need to backtrack, but backtracking support in modern programming environments is limited. Previously, we have conducted a series of studies, which discovered that backtracking in programming is in fact prevalent and programmers need better backtracking tools. In this demonstration, we will present our backtracking tool called AZURITE,

Semiquantitative theory for high-field low-temperature properties of a distorted diamond spin chain

open access: yesCondensed Matter Physics, 2012
We consider the antiferromagnetic Heisenberg model on a distorted diamond chain and use the localized-magnon picture adapted to a distorted geometry to discuss some of its high-field low-temperature properties.
