用波长全息构造量子场论

Holographic Construction of Quantum Field Theory using Wavelets

Sukhwinder Singh, Gavin K. Brennen

摘要:

小波以多种分辨率对数据进行编码,这在量子场论的小波描述中,允许场除了时空坐标之外还携带额外的维度:尺度。最近引入的精确全息映射[C.H.李和X L. Qi,Phys.Rev.B93,035112(2016)]使用Haar小波基来表示多个重整化尺度下的自由狄拉克费米子量子场论(QFT),从而在一个更高维度中诱导出涌现的体几何。这种结构是,事实上,通用的,我们展示了如何更高的家庭的Daubechies小波变换的1+1维标量玻色子QFT产生大量的描述与重整化流的可变速率。在无质量的情况下,其中的边界是由共形场论描述的,散装相关衰减与反德西特空间(AdS 3)度量的曲率曲率半径取决于所使用的小波族一致的距离。我们提出了一个实验演示的体积/边界对应通过数字量子模拟使用高斯操作的一组量子谐振子模式。

英文摘要:

Wavelets encode data at multiple resolutions, which in a wavelet description of a quantum field theory, allows for fields to carry, in addition to space-time coordinates, an extra dimension: scale. A recently introduced Exact Holographic Mapping [C.H. Lee and X.-L. Qi, Phys. Rev. B 93, 035112 (2016)] uses the Haar wavelet basis to represent the free Dirac fermionic quantum field theory (QFT) at multiple renormalization scales thereby inducing an emergent bulk geometry in one higher dimension. This construction is, in fact, generic and we show how higher families of Daubechies wavelet transforms of 1+1 dimensional scalar bosonic QFT generate a bulk description with a variable rate of renormalization flow. In the massless case, where the boundary is described by conformal field theory, the bulk correlations decay with distance consistent with an Anti-de-Sitter space (AdS3) metric whose radius of curvature depends on the wavelet family used. We propose an experimental demonstration of the bulk/boundary correspondence via a digital quantum simulation using Gaussian operations on a set of quantum harmonic oscillator modes.
