格点AdS几何与连续极限

Lattice AdS Geometry and Continuum Limit

Chen-Te Ma

摘要:

我们构造了格AdS几何。格点AdS $_2$几何和格点AdS $_3$几何可以由格点AdS $_2$诱导度规推广而来,它提供了经典极限下的格点Schwarzian理论.然后利用格点嵌入坐标重写了格点AdS $_2$几何和AdS $_3$几何,并给出了它们的显等距图.格点AdS $_2$几何可以由格点AdS $_3$几何通过紧致化得到,而不需要格点伪影.格嵌入坐标也可以用于高维AdS几何中。由于格点Schwarzian理论不存在连续极限的问题,格点AdS $_2$几何可以由高维AdS几何通过紧化得到,并且格点AdS度量不依赖于角坐标,我们期望由这种几何格点AdS几何得到的格点Einstein引力理论应该存在连续极限.最后,我们应用这种晶格结构来构造全息张量网络,而不需要连续极限。

英文摘要:

We construct the lattice AdS geometry. The lattice AdS$_2$ geometry and AdS$_3$ geometry can be extended from the lattice AdS$_2$ induced metric, which provided the lattice Schwarzian theory at the classical limit. Then we use the lattice embedding coordinates to rewrite the lattice AdS$_2$ geometry and AdS$_3$ geometry with the manifest isometry. The lattice AdS$_2$ geometry can be obtained from the lattice AdS$_3$ geometry through the compactification without the lattice artifact. The lattice embedding coordinates can also be used in the higher dimensional AdS geometry. Because the lattice Schwarzian theory does not suffer from the issue of the continuum limit, the lattice AdS$_2$ geometry can be obtained from the higher dimensional AdS geometry through the compactification, and the lattice AdS metric does not depend on the angular coordinates, we expect that the continuum limit should exist in the lattice Einstein gravity theory from this geometric lattice AdS geometry. Finally, we apply this lattice construction to construct the holographic tensor network without the issue of a continuum limit.
