大电荷下的玻色子与费米子理论的研究

A study of Bosonic and Fermionic Theories at Large Charge

Ioannis Kalogerakis

AI总结:

本文利用大量子数展开系统研究强耦合玻色子与费米子共形场论,将其转化为弱耦合有效场论,并探讨玻色子共形超流体与费米球等凝聚态系统。

摘要:

本论文旨在利用大量子数展开,系统且一致地研究强耦合的玻色子与费米子共形场论。其背后的思想是研究共形场论中由全局对称性下的大量子数所表征的扇区。在此极限下,即使共形场论最初是强耦合且相互作用的,现在也可以用弱耦合的有效场论来描述。文献中常见的一些有效场论包括玻色子共形超流体和费米球,它们是具有高粒子密度的凝聚态物质系统,这使得此类系统的研究成为一个跨学科课题。

英文摘要:

The aim of this thesis is to systematically and consistently study strongly coupled bosonic and fermionic conformal field theories using the large quantum number expansion. The idea behind it is to study sectors of conformal field theories that are characterised by large quantum numbers under global symmetries. In this limit, the conformal field theories, even if they initially were strongly coupled and interacting, can now be written in terms of an effective field theory that is weakly coupled. Some common effective field theories that appear in the literature are the bosonic conformal superfluid and the Fermi sphere, condensed matter systems characterised by a high particle density, making the study of such systems a cross-disciplinary matter.
