ABJM理论中的涡旋型半BPS孤子

Vortex-type Half-BPS Solitons in ABJM Theory

Chanju Kim, Yoonbai Kim, O-Kab Kwon, Hiroaki Nakajima

摘要:

我们研究了有和无质量形变的Aharony-Bergman-Jafferis-Maldacena(ABJM)理论。结果表明,最大超对称保持,D-项,F-项质量变形的单一质量参数是等价的。我们得到了涡型半BPS方程和相应的能量界。对于未变形的ABJM理论,得到的半BPS方程与超对称Yang-Mills理论的半BPS方程相同,且不存在有限能量正则BPS解;对于质量变形的ABJM理论,U(2)xU(2)情形的半BPS方程退化为Maxwell-Higgs理论的涡旋方程,支持静态正则多涡旋解。在U(N)xU(N)且N>2的情况下,得到了Yang-Mills-Higgs理论的非交换涡旋方程。

英文摘要:

We study Aharony-Bergman-Jafferis-Maldacena (ABJM) theory without and with mass deformation. It is shown that maximally supersymmetry preserving, D-term, and F-term mass deformations of single mass parameter are equivalent. We obtain vortex-type half-BPS equations and the corresponding energy bound. For the undeformed ABJM theory, the resulting half-BPS equation is the same as that in supersymmetric Yang-Mills theory and no finite energy regular BPS solution is found. For the mass-deformed ABJM theory, the half-BPS equations for U(2)xU(2) case reduce to the vortex equation in Maxwell-Higgs theory, which supports static regular multi-vortex solutions. In U(N)xU(N) case with N>2 the nonabelian vortex equation of Yang-Mills-Higgs theory is obtained.
