摘要:

预凝聚是相变中的一种奇特现象,其特征是凝聚态只在有限的长度尺度范围内出现。它与平衡状态下领域、伪间隙相和空间非均匀性的确立密切相关。在本文中,我们展示了在楚尔极限下,规范-费米理论中热楚尔相变附近预凝聚现象的发生。我们进一步表明,随着费米子味数的增加,预凝聚区域变得更加显著,并扩展到更宽的温度范围。我们分析了由广泛类别的费米子系统共享的基本动力学,从凝聚态到高能物理。具体而言,我们讨论了这一现象对超出标准模型物理的潜在相关性。

英文摘要:

Precondensation is a peculiar phenomenon in phase transitions, characterised by the occurrence of a condensate only over a finite range of length scales. It is closely connected to the emergence of domains, pseudo-gapped phases and spatial inhomogeneities in equilibrium. In this work, we show its occurrence in gauge-fermion theories in the chiral limit, close to the thermal chiral phase transition. We further show that the precondensation regime becomes increasingly pronounced and extends over a wider temperature range as the number of fermion flavours is increased. We analyse the underlying dynamics which is shared by a broad class of fermionic systems, ranging from condensed matter to high-energy physics. Specifically, we discuss the potential relevance of this phenomenon for physics beyond the Standard Model.
