矩阵模型中的紧化旋转膜和朝向一圈的激发谱

Compactified rotating branes in the matrix model, and excitation spectrum towards one loop

Daniel N. Blaschke, Harold C. Steinacker

摘要:

本文研究了IIB矩阵模型中R^4 x K型紧化膜解,得到了计算单圈有效作用量所需的玻色子和费米子涨落谱。我们验证了单圈贡献对R^4 x T^2是UV有限的,对R^3 x S^1是超对称的。在T^2上存在通量的情况下,高阶卡鲁扎-克莱因模存在能隙,并讨论了与稳定性有关的潜在问题。

英文摘要:

We study compactified brane solutions of type R^4 x K in the IIB matrix model, and obtain explicitly the bosonic and fermionic fluctuation spectrum required to compute the one-loop effective action. We verify that the one-loop contributions are UV finite for R^4 x T^2, and supersymmetric for R^3 x S^1. The higher Kaluza-Klein modes are shown to have a gap in the presence of flux on T^2, and potential problems concerning stability are discussed.
