分形和来自膜的奇异对称性

Fractons and exotic symmetries from branes

摘要:

分形子是一种新型的准粒子,具有受限制的迁移率,它的研究激发了几类有趣的具有新性质的连续量子场论的构建。其中一类是叶状场论,它们大致上是通过将支持在时空叶状物的叶上的场耦合在一起而建立的。另一种方法,我们称之为奇异场论,专注于构造与分形物理学相邻的特殊对称性(如子系统对称性)一致的拉格朗日量。第三个框架是无限分量Chern-Simons理论,它试图将传统的Chern-Simons理论在描述(2+1)D Abel拓扑序中的作用推广到(3+1)D的分形序。对这些理论的研究仍在进行中,它们的许多性质仍有待理解。从历史上看,将QFT嵌入弦论的研究是卓有成效的。其中一种方法是通过D膜,即扩展的物体,其动力学在低能量下可以用传统的量子场论来描述。可以用这种方法实现的量子场论,可以用弦论丰富的数学和物理结构来分析。在本文中,我们表明,叶状场论,奇异的场论,和无限分量的陈-西蒙斯理论都可以实现上的世界体积膜。我们希望这些构造最终能对这些有趣的场论的物理学产生有价值的见解。

英文摘要:

The emerging study of fractons, a new type of quasi-particle with restricted mobility, has motivated the construction of several classes of interesting continuum quantum field theories with novel properties. One such class consists of foliated field theories which, roughly, are built by coupling together fields supported on the leaves of foliations of spacetime. Another approach, which we refer to as exotic field theory, focuses on constructing Lagrangians consistent with special symmetries (like subsystem symmetries) that are adjacent to fracton physics. A third framework is that of infinite-component Chern-Simons theories, which attempts to generalize the role of conventional Chern-Simons theory in describing (2+1)D Abelian topological order to fractonic order in (3+1)D. The study of these theories is ongoing, and many of their properties remain to be understood. Historically, it has been fruitful to study QFTs by embedding them into string theory. One way this can be done is via D-branes, extended objects whose dynamics can, at low energies, be described in terms of conventional quantum field theory. QFTs that can be realized in this way can then be analyzed using the rich mathematical and physical structure of string theory. In this paper, we show that foliated field theories, exotic field theories, and infinite-component Chern-Simons theories can all be realized on the world-volumes of branes. We hope that these constructions will ultimately yield valuable insights into the physics of these interesting field theories.
