Branes Screening Quarks and Defect Operators
Andreas Karch, Marcos Riojas
Here we generalize a well-known computation and uncover a phase-transition, showing that Wilson lines do not necessarily exhibit Coulomb scaling laws in AdS/BCFT at zero temperatur…

The boundary entropy function for interface conformal field theories
Evangelos Afxonidis, Andreas Karch, Chitraang Murdia
{In 1+1 dimensional conformal field theory with a boundary the boundary contribution to the entanglement entropy is determined by a single number effectively counting the bound…
