Binary Black Holes and Quantum Off-Shell Recursion
Kyoungho Cho, Kwangeon Kim, Kanghoon Lee
The quantum off-shell recursion provides an efficient and universal computational tool for loop-level scattering amplitudes. In this work, we present a new comprehensive computatio…
Perturbations of General Relativity to All Orders and the General Order Terms
Kyoungho Cho, Kwangeon Kim, Kanghoon Lee
We derive all-order expressions for perturbations of the Einstein-Hilbert action and the Einstein equation with the general -th order terms. To this end, we employ Cheung and Re…
The Off-Shell Recursion for Gravity and the Classical Double Copy for currents
Kyoungho Cho, Kwangeon Kim, Kanghoon Lee
We construct the off-shell recursion for gravity and the graviton current for the perturbative double field theory (DFT). We first formulate the perturbative DFT, which is equivale…
The Classical Double Copy for Half-Maximal Supergravities and T-duality
Stephen Angus, Kyoungho Cho, Kanghoon Lee
We study the classical double copy for ungauged half-maximal supergravities using the Kaluza-Klein reduction of double field theory (DFT). We construct a general formula for the Ka…
Stringy Newton Gravity with -flux
Kyoungho Cho, Kevin Morand, Jeong-Hyuck Park
A Symmetry Principle has been shown to augment unambiguously the Einstein Field Equations, promoting the whole closed-string massless NS-NS sector to stringy graviton fields. Here…
Remarks on the non-Riemannian sector in Double Field Theory
Kyoungho Cho, Jeong-Hyuck Park
Taking covariant field variables as its truly fundamental constituents, Double Field Theory can accommodate not only conventional supergravity but also non-Rieman…
completion of the Friedmann equations
Stephen Angus, Kyoungho Cho, Guilherme Franzmann +2
In string theory the closed-string massless NS-NS sector forms a multiplet of symmetry. This suggests a specific modification to General Relativity in which the e…
Emulating topological currents arising from a dipolar parity anomaly in two-dimensional optical lattices
Zhi Lin, Xian-Jia Huang, Dan-Wei Zhang +2
Dipolar parity anomaly can be induced by spatiotemporally weak-dependent energy-momentum separation of paired Dirac points in two-dimensional Dirac semimetals. Here we reveal topol…
Einstein Double Field Equations
Stephen Angus, Kyoungho Cho, Jeong-Hyuck Park
Upon treating the whole closed string massless sector as stringy graviton fields, Double Field Theory may evolve into Stringy Gravity, i.e. the stringy augmentation of General Rela…
2D Seiberg-like dualities with an adjoint matter
Kyoungho Cho, Hyungchul Kim, Jaemo Park
We consider the analogue of Kutasov-Schwimmer-Seiberg duality for two-dimensional gauge theory with one adjoint with the superpotential $\Tr X^{l+1}$…
