一圈处的光谱墙

Spectral Walls at One Loop

Jarah Evslin, Chris Halcrow, Tomasz Romanczukiewicz, Andrzej Wereszczynski

摘要:

谱壁是经典BPS孤子的模空间中的一个表面,其中内部激发穿过连续质量阈值。最近的研究表明,经典场论中的谱壁排斥其相应的内部激发被激发的孤子。我们调查,为第一次,在量子理论中的频谱墙的命运,计算瞬时加速度的波包的经典BPS反扭结在杂质的存在下。我们发现,在量子理论中,即使束缚模没有被激发,反扭结也是排斥的。也许由于这种排斥力,光谱壁的戏剧性经典效应在我们的量子计算中看不到。

英文摘要:

A spectral wall is a surface in a moduli space of classically BPS solitons where an internal excitation crosses the continuum mass threshold. It has recently been shown that spectral walls in classical field theory repel solitons whose corresponding internal excitations are excited. We investigate, for the first time, the fate of spectral walls in a quantum theory, calculating the instantaneous acceleration of a wave packet of classically BPS antikinks in the presence of an impurity. We find that, in the quantum theory, the antikinks are repelled even when the bound mode is not excited. Perhaps due to this repulsive force, the dramatic classical effects of the spectral wall are not seen in our quantum calculation.
