全息超导模型

Models of Holographic superconductivity

Francesco Aprile, Jorge G. Russo

摘要:

我们构建了一般模型的全息超导参数化的三个耦合,这是一个真正的标量场的功能,并表明,在一般的假设下,他们描述超导相变。虽然一些特征是通用的和模型无关的,但量子临界行为的重要方面强烈依赖于耦合的选择,例如相变的阶数和二阶相变的临界指数。特别是,我们研究了一个单参数模型,其中的相变从二阶到一阶以上的一些临界值的参数和可调的临界指数的模型。

英文摘要:

We construct general models for holographic superconductivity parametrized by three couplings which are functions of a real scalar field and show that under general assumptions they describe superconducting phase transitions. While some features are universal and model independent, important aspects of the quantum critical behavior strongly depend on the choice of couplings, such as the order of the phase transition and critical exponents of second-order phase transitions. In particular, we study a one-parameter model where the phase transition changes from second to first order above some critical value of the parameter and a model with tunable critical exponents.
