Matèria condensada Física de partícules Condensed matter Particle physics The loss of criticality in the form of weak first-order transitions or the end of the conformal window in gauge theories can be described as the merging of two fixed points that move to complex values of the couplings. When the complex fixed points are close to the real axis, the system typically exhibits walking behavior with Miransky (or Berezinsky-Kosterlitz-Thouless) scaling. We present a novel realization of these phenomena at strong coupling by means of the gauge/gravity duality, and give evidence for the conjectured existence of complex conformal field theories at the fixed points. 2020-12-15T10:41:44Z 2020-12-15T10:41:44Z 2020-04-20 2020-12-15T10:41:44Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: https://doi.org/10.1103/PhysRevLett.124.161601 Physical Review Letters, 2020, vol. 124, num. 16, p. 161601 https://doi.org/10.1103/PhysRevLett.124.161601 cc by (c) American Physical Society, 2020 http://creativecommons.org/licenses/by/3.0/es/ info:eu-repo/semantics/openAccess American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
