Quantum Criticality and DBI Magneto-resistance
arXiv:1608.02598 · doi:10.1088/1751-8121/aa59c6
Abstract
We use the DBI action from string theory and holography to study the magneto-resistance at quantum criticality with hyperscaling violation. We find and analyze a rich class of scaling behaviors for the magneto-resistance. A special case describes the scaling results found in pnictides by Hayers et al. in~\cite{analytis}.
