动量耗散全息的磁输运
Magneto-transport from momentum dissipating holography
摘要:
我们得到了显式表达式的热电输运系数的强耦合,平面介质中存在的正交磁场和动量耗散过程。计算是在规范/重力框架内进行的,其中引入了动量耗散机制,包括质量项的散装引力子。依赖于计算的输运系数的结构,并促进参数成为动力学函数,我们提出了一个全息启发的现象学开放的直接比较与实验数据的铜酸盐。
英文摘要:
We obtain explicit expressions for the thermoelectric transport coefficients of a strongly coupled, planar medium in the presence of an orthogonal magnetic field and momentum-dissipating processes. The computations are performed within the gauge/gravity framework where the momentum dissipation mechanism is introduced by including a mass term for the bulk graviton. Relying on the structure of the computed transport coefficients and promoting the parameters to become dynamical functions, we propose a holography inspired phenomenology open to a direct comparison with experimental data from the cuprates.
