Scattering off Chamblin-Reall Branes
Dongsheng Ge, Christopher P. Herzog
We study the linearized scattering of dilaton-graviton waves from a thin brane in three-dimensional spacetime. Holographically, the setup models scattering from an interface in a f…
How to get an interacting conformal line defect for free theories
Samuel Bartlett-Tisdall, Dongsheng Ge, Christopher P. Herzog
We argue that interacting conformal line defects in free quantum field theories can exist, provided that inversion symmetry is broken. Important for our demonstration is the existe…
Non-Factorizing Interface in the Two-Dimensional Long-Range Ising Model
Dongsheng Ge, Yu Nakayama
The factorization proposal claims that the co-dimension one "pinning defect", on which a local relevant operator is integrated, factorizes the space into two halves in general conf…
Localized RG flows on composite defects and -theorem
Dongsheng Ge, Tatsuma Nishioka, Soichiro Shimamori
We consider a composite defect system where a lower-dimensional defect (sub-defect) is embedded to a higher-dimensional one, and examine renormalization group (RG) flows localized…
Boundary-induced transitions in Möbius quenches of holographic BCFT
Alice Bernamonti, Federico Galli, Dongsheng Ge
Boundary effects play an interesting role in finite-size physical systems. In this work, we study the boundary-induced properties of 1+1-dimensional critical systems driven by inho…
Holographic Path-Integral Optimization
Jan Boruch, Pawel Caputa, Dongsheng Ge +1
In this work we elaborate on holographic description of the path-integral optimization in conformal field theories (CFT) using Hartle-Hawking wave functions in Anti-de Sitter space…
