DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QTFMS/8/">De
 fect Conformal Manifolds from Phantom (Non-Invertible) Symmetries</a>\nby 
 Andrea Antinucci (University of Oxford) as part of Quantum Theories of Fie
 lds\, Matter\, and Strings\n\n\nAbstract\nConformal defects have a variety
  of physical applications\, serving for instance as universality classes o
 f impurities in critical systems. When they break a continuous symmetry of
  the system\, they arise in families related by exactly marginal deformati
 ons. While these defect conformal manifolds are interesting in their own r
 ight\, many physical properties—such as the reflection coefficient—rem
 ain constant across the manifold. After reviewing these known facts\, in t
 his talk I will present a new mechanism through which defect conformal man
 ifolds can arise even in the absence of broken continuous symmetries. In t
 his case\, physical properties are no longer constant along the manifold\,
  yet they remain calculable and exhibit interesting behaviour. I will illu
 strate this mechanism with examples in (1+1)D CFTs and comment on possible
  generalizations to higher dimensions.\n
