Critical theory of Pomeranchuk transitions via high-dimensional bosonization (opens in new tab)

Author(s): Zhengfei Hu, Jaychandran Padayasi, Oğuz Türker, and Kun YangWe use high-dimensional bosonization to derive an effective field theory that describes the Pomeranchuck transition in isotropic two-dimensional Fermi liquids. We find that the transition is triggered by the softening of an eigenmode that leads to spontaneous Fermi surface distortion. The resultant …[Phys. Rev. B 113, L241116] Published Mon Jun 22, 2026
