Evidence for magnetic clusters in stoichiometric quantum critical CeRuSi
Alex Bretaña, Sean Fayfar, Wouter Montfrooij
Systems that have been prepared to undergo a second-order phase transition at zero Kelvin, the so-called quantum critical systems, appear to fall into two categories: (chemically)…

The effects of disorder on Harris-criterion violating percolation
Sean Fayfar, Alex Bretaña, Wouter Montfrooij
We present the results of computer simulations on a class of percolative systems, called protected percolation, that violates the Harris criterion. The Harris criterion states whet…

Protected percolation: a new universality class pertaining to heavily-doped quantum critical systems
Sean Fayfar, Alex Bretaña, Wouter Montfrooij
We present the results of computer simulations on a class of percolative systems that forms a new universality class. We show the results for the critical exponents for this new cl…
