Planck mass gravitinos in Einstein-Maxwell backgrounds
Artur Krawczyk, Krzysztof A. Meissner, Hermann Nicolai +1
Charged massive spin-3/2 fields have long been regarded as problematic, because their coupling to electromagnetism generically leads to loss of hyperbolicity, acausal propagation a…
Geometric realization of stress-tensor deformed field theory
Yun-Ze Li, Yunfei Xie, Song He
We present a semiclassical framework in which stress-tensor deformations of a quantum field theory (QFT) reorganize into a gravitational action evaluated at a metric saddle. The de…
Character of the highest weight module of BMS algebra realized on codimensional-two boundary
Bin Chen, Song He, Pujian Mao +1
In this paper, we investigate the highest weight representation (HWR) of the three and four-dimensional Bondi-Metzner-Sachs (BMS) algebra realized on the codimension-two boundary o…
Observables and Unconstrained Spin Tensor Dynamics in General Relativity from Scattering Amplitudes
Mark Alaverdian, Zvi Bern, Dimitrios Kosmopoulos +4
In a previous Letter, we showed that physical scattering observables for compact spinning objects in general relativity can depend on additional degrees of freedom in the spin tens…
From Modular Graph Forms to Iterated Integrals
Emiel Claasen, Mehregan Doroudiani
Modular graph forms are a class of non-holomorphic modular forms that arise in the low-energy expansion of genus-one closed string amplitudes. In this work, we introduce a systemat…
Radiation eikonal for post-Minkowskian observables
Jung-Wook Kim
A recent proposal reinterprets the eikonal as the scattering generator, which computes scattering observables through an action as a symmetry generator. The aim of this study is to…
Type II superstring amplitude at one-loop and transcendentality
Emiel Claasen, Mehregan Doroudiani
We calculate the four-graviton scattering amplitude in Type II superstring theory at one loop up to seventh order in the low-energy expansion through the recently developed iterate…
Emergence of Calabi-Yau manifolds in high-precision black hole scattering
Mathias Driesse, Gustav Uhre Jakobsen, Albrecht Klemm +5
Using the worldline quantum field theory formalism, we compute the radiation-reacted impulse, scattering angle, radiated energy and recoil of a classical black hole (or neutron sta…
Shear transport in far-from-equilibrium isotropization of supersymmetric Yang-Mills plasma
Shoucheng Wang, Song He, Li Li
We holographically study the far-from-equilibrium isotropization dynamics of the strongly coupled supersymmetric Yang-Mills plasma. The dual gravitational backgroun…
Holographic deformation of the entanglement entropy in (A)dS/CFT
Jing-Cheng Chang, Song He, Yu-Xiao Liu +1
In recent years, the holographic duality between -deformed conformal field theory (CFT) and Anti-de Sitter (AdS) spacetime with finite radial cutoff has received signific…
Torus reduction of maximal conformal supergravity
Franz Ciceri, Axel Kleinschmidt, Subrabalan Murugesan +1
We consider the dimensional reduction of N=(2,0) conformal supergravity in six dimensions on a two-torus to N=4 conformal supergravity in four dimensions. At the level of kinematic…
Massive twistor worldline in electromagnetic fields
Joon-Hwi Kim, Jung-Wook Kim, Sangmin Lee
We study the (ambi-)twistor model for spinning particles interacting via electromagnetic field, as a toy model for studying classical dynamics of gravitating bodies including effec…
Geometric formulation of generalized root- deformations
H. Babaei-Aghbolagh, Song He, Tommaso Morone +2
We develop a generic geometric formalism that incorporates both -like and root--like deformations in arbitrary dimensions. This framework applies to a wide fami…
Coupling of Branes and Twisted Self-Duality in the Maxwell-Chern-Simons Theory
Hannes Malcha
We study three approaches to electric-magnetic duality in the 4-dimensional Maxwell theory coupled to a dyonic point charge and in the 5-dimensional Maxwell-Chern-Simons (MCS) theo…
Detecting quantum chaos via pseudo-entropy
Song He, Pak Hang Chris Lau, Long Zhao
Quantum informatic quantities such as entanglement entropy are useful in detecting quantum phase transitions. Recently, a new entanglement measure called pseudo-entropy was propose…
Irrelevant and marginal deformed BMS field theories
Song He, Xin-Cheng Mao
In this study, we investigate various deformations within the framework of Bondi-van der Burg-Metzner-Sachs invariant field theory (BMSFT). Specifically, we explore the impact of B…
Integral of depth zero to three basis of Modular Graph Functions
Mehregan Doroudiani
Modular Graph Functions (MGFs) are SL(2,)-invariant functions that emerge in the study of the low-energy expansion of the one-loop closed string amplitude. To find the…
Systematic approach to correlators in deformed CFTs
Song He, Yuan Sun, Jiashi Yin
We investigate higher-order corrections to correlators in a general CFT (conformal field theory) with the double-trace deformation. Standard perturbation theory proves i…
Maximal D=2 supergravities from higher dimensions
Guillaume Bossard, Franz Ciceri, Gianluca Inverso +1
We develop in detail the general framework of consistent Kaluza-Klein truncations from D=11 and type II supergravities to gauged maximal supergravities in two dimensions. In partic…
A small Universe
Jean-Luc Lehners, Jerome Quintin
Many cosmological models assume or imply that the total size of the universe is very large, perhaps even infinite. Here we argue instead that the universe might be comparatively sm…
Island formula in Planck brane
Jing-Cheng Chang, Song He, Yu-Xiao Liu +1
Double holography offers a profound understanding of the island formula by describing a gravitational system on AdS coupled to a conformal field theory on ,…
Renormalizing Love: tidal effects at the third post-Newtonian order
Manoj K. Mandal, Pierpaolo Mastrolia, Hector O. Silva +2
We present the conservative effective two-body Hamiltonian at the third order in the post-Newtonian expansion with gravitoelectric quadrupolar dynamical tidal-interactions. Our der…
Loop corrections versus marginal deformation in celestial holography
Song He, Pujian Mao, Xin-Cheng Mao
Four-dimensional all-loop amplitudes in QED and gravity exhibit universal Infrared (IR) singularities with a factorization structure. This structure is governed by tree amplitudes…
Conformal anomalies in 6d 4-derivative theories: a heat-kernel analysis
Lorenzo Casarin
We compute the conformal anomalies for some higher-derivative (non-unitary) 6d Weyl invariant theories using the heat-kernel expansion in the background-field method. To this aim w…
