NUT弦的Gregory-Laflamme不稳定性和非一致推广

The Gregory-Laflamme instability and non-uniform generalizations of NUT strings

Burkhard Kleihaus, Jutta Kunz, Eugen Radu

摘要:

我们通过线性微扰理论探讨了NUT弦的Gregory-Laflamme不稳定性(即D=4洛伦兹NUT解提升到5维)。我们的结果表明,存在NUT电荷$n$时,Gregory-Laflamme不稳定性仍然存在,对于相同的质量值,额外维的临界长度随$n$的增加而增加. NUT弦的非均匀分支数值扩展到全非线性区域。

英文摘要:

We explore via linearized perturbation theory the Gregory-Laflamme instability of the NUT string (i.e the D=4 Lorentzian NUT solution uplifted to five dimensions). Our results indicate that the Gregory-Laflamme instability persists in the presence of a NUT charge $n$, the critical length of the extra-dimension increasing with $n$ for the same value of mass. The non-uniform branch of NUT strings is numerically extended into the full nonlinear regime.
