Impurities Near the Light Cone
Gabriel Cuomo, Simone Giombi, Luigi Tizzano
The lightlike Wilson line cusp underlies the Sudakov double logarithm and is a central ingredient in gauge-theory factorization. We ask what replaces this behavior for general conf…

Bouncing singularities and thermal correlators on line defects
Simone Giombi, Yue-Zhou Li, Jieru Shan
Thermal correlators in holographic conformal field theories are known to exhibit singularities in complex time, sometimes referred to as ``bouncing singularities", which are believ…

Line Defects with a Cusp in Fermionic CFTs
Simone Giombi, Anurag Pendse
We study line defects with a cusp in fermionic CFTs arising as fixed points of scalar-fermion theories with Yukawa interactions. These include the Gross-Neveu-Yukawa model and some…
