Holographic model for antiferromagnetic quantum phase transition induced by magnetic field CaiRong-Gen YangRun-Qiu KusmartsevFeodor 2015 We 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.
