We find the first example of a quantum Berenzinskii-Kosterlitz-Thouless (BKT) phase transition in two spatial dimensions via holography. This transition occurs in the D3/D5 system at nonzero density and magnetic field. At any nonzero temperature, the BKT scaling is destroyed and the transition becomes second order with mean-field exponents. We go on to conjecture about the generality of quantum BKT transitions in two spatial dimensions.
我们通过全息术发现了第一个二维量子 Berezinskii-Kosterlitz-Thouless（BKT）相变的例子。这个相变发生在非零密度和磁场的 D3/D5 系统中。在任何非零温度下，BKT 标度都会被破坏，相变变成具有平均场指数的二级相变。我们继续推测二维量子 BKT 相变的普遍性。
