Nonrenormalization Theorem for ${cal N}=(4,4)$ Interface Entropy

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Andreas Karch, Hirosi Ooguri, Mianqi Wang, , | Summary: We derive a formula for the half-BPS interface entropy between any pair of ${cal N}=(4,4)$ theories on the same conformal manifold. This generalizes the diastasis formula derived in arXiv:1311.2202 for ${cal N}=(2,2)$ theories, which is restricted to the […]

Evolving dark energy models: Current and forecast constraints

Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Anowar J. Shajib, Joshua A. Frieman, , , | Summary: Recent results from Type Ia supernovae (SNe Ia) and baryon acoustic oscillations (BAO), in combination with cosmic microwave background (CMB) measurements, have focused renewed attention on dark energy models with a time-varying equation-of-state parameter, $w(z)$. In […]

Reconstructing the shape of the non-linear matter power spectrum using CMB lensing and cosmic shear

Kavli Affiliate: Blake Sherwin | First 5 Authors: Karen Perez Sarmiento, Alex LaguĂ«, Mathew Madhavacheril, Bhuvnesh Jain, Blake Sherwin | Summary: We reconstruct the non-linear matter power spectrum $P(k)$ using a joint analysis of gravitational lensing of the cosmic microwave background (CMB) and lensing of galaxies. This reconstruction is motivated by the $S_8$ tension between […]
