各向异性Unruh温度

Anisotropic Unruh temperatures

Raul Arias, Horacio Casini, Marina Huerta, Diego Pontello

摘要:

非常高能量的局域激发和真空之间的相对熵,其中两个状态都被减少到一个空间区域,让位于一个精确的定义所产生的局部温度的真空纠缠跨越边界。这将Rindler楔的Unruh温度推广到任意区域。局部温度可以从模哈密顿量中的短距离前导项读出。对于自由标量场和费米子场,它们有一个通用的几何表达式,可以通过在欧几里得空间中求解一个特定的程函型方程来实现。这个方程把二维中的全纯性质推广到任何维。对于任意形状的区域,一点的局部温度是方向相关的。我们计算它们的显式表达式的几何形状的墙或带。

英文摘要:

The relative entropy between very high energy localized excitations and the vacuum, where both states are reduced to a spatial region, gives place to a precise definition of a local temperature produced by vacuum entanglement across the boundary. This generalizes the Unruh temperature of the Rindler wedge to arbitrary regions. The local temperatures can be read off from the short distance leading terms in the modular Hamiltonian. For free scalar and fermion fields they have a universal geometric expression that follows by solving a particular eikonal type equation in Euclidean space. This equation generalizes to any dimension the holomorphic property that holds in two dimensions. For regions of arbitrary shapes the local temperatures at a point are direction dependent. We compute their explicit expression for the geometry of a wall or strip.
