The Photon Sphere and Response Functions in Holography
Marcos Riojas, Hao-Yu Sun
In this letter, we show the Unruh temperature of the photon sphere for an AdS-Schwarzschild black hole can be determined holographically from the retarded Green's function and…
Universality of Effective Central Charge in Interface CFTs
Andreas Karch, Yuya Kusuki, Hirosi Ooguri +2
When an interface connects two CFTs, the entanglement entropy between the two CFTs is determined by a quantity called the effective central charge. The effective central charge doe…
Towards -finiteness: -deformed open string amplitude
Yuqi Li, Hao-Yu Sun
Revisiting the Coon amplitude, a deformation of the Veneziano amplitude with a logarithmic generalization of linear Regge trajectories, we scrutinize its potential origins in a wor…
The Photon Sphere and the AdS/CFT Correspondence
Marcos Riojas, Hao-Yu Sun
The AdS/CFT correspondence connects bulk fields to boundary operators characterized by source frequency and angular momentum . Here we explore their connec…
Imprints of phase transitions on Kasner singularities
Elena Caceres, Sanjit Shashi, Hao-Yu Sun
Under the AdS/CFT correspondence, asymptotically AdS geometries with backreaction can be viewed as CFT states subject to a renormalization group (RG) flow from an ultraviolet (UV)…
Spacetime Subsystem Symmetries
Saba Asif Baig, Jacques Distler, Andreas Karch +2
One characteristic feature of many fractonic lattice models, and a defining property of the exotic field theories developed to describe them, are subsystem symmetries including a c…
Constructing Carrollian Field Theories from Null Reduction
Bin Chen, Reiko Liu, Haowei Sun +1
In this paper, we propose a novel way to construct off-shell actions of -dimensional Carrollian field theories by considering the null-reduction of the Bargmann invariant action…
