Holographic model for antiferromagnetic quantum phase transition induced by magnetic field
journal contribution
posted on 2015-11-13, 11:51 authored by Rong-Gen Cai, Run-Qiu Yang, Feodor KusmartsevWe propose a gravity dual of antiferromagnetic quantum phase transition induced by magnetic field and study the critical behavior around the quantum critical point. It turns out that the boundary critical theory is a strong coupling theory with dynamic exponent z ¼ 2 and that the hyperscaling law is violated and
logarithmic corrections appear near the quantum critical point. Some novel scaling relations are predicated, which can be tested by experiment data in the future. We also make some comparison with experimental
data on low-dimensional magnets BiCoPO5 and pyrochlores Er2−2xY2xTi2O7.
