Yui Hayashi

AI总结:

本文通过格点模型显式计算证明了具有基本物质场的规范理论中Aharonov-Bohm相在禁闭相与Higgs相间平滑连接,支持Higgs-禁闭连续性,为致密QCD等具有超流性的规范理论相结构提供了新见解。

摘要:

某些具有自发破缺$U(1)$对称性的规范理论在Higgs相中表现出围绕涡旋的分数Aharonov-Bohm (AB) 相。我们讨论了此类具有基本物质场的规范理论中禁闭相与Higgs相之间的连续性,重点关注AB相。通过对相关格点模型进行显式计算,我们证明了AB相在禁闭相与Higgs相之间平滑连接,支持了Higgs-禁闭连续性。该结果为具有超流性的规范理论(如致密QCD)的相结构提供了新见解。

英文摘要:

Some gauge theories with a spontaneously broken $U(1)$ symmetry exhibit fractional Aharonov-Bohm (AB) phases around vortices in the Higgs regime. We discuss continuity between confining and Higgs regimes in such gauge theories with fundamental matter fields, focusing on the AB phases. By explicit calculations in relevant lattice models, we demonstrate that the AB phase is smoothly connected between the confining and Higgs regimes, supporting the Higgs-confinement continuity. This result provides new insight into phase structures of gauge theories with superfluidity, such as dense QCD.
