Three roads to the geometric constraint formulation of gravitational theories with boundaries

Kavli Affiliate: J. S. Villasenor | First 5 Authors: Fernando Barbero, Marc Basquens, Valle Varo, Eduardo J. S. VillaseƱor, | Summary: The Hamiltonian description of mechanical or field models defined by singular Lagrangians plays a central role in physics. A number of methods are known for this purpose, the most popular of them being the […]

Probing Extremal Gravitational-Wave Events with Coarse-Grained Likelihoods

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Reed Essick, Amanda Farah, Shanika Galaudage, Colm Talbot, Maya Fishbach | Summary: As catalogs of gravitational-wave transients grow, new records are set for the most extreme systems observed to date. The most massive observed black holes probe the physics of pair instability supernovae while providing clues […]

Subregion Spectrum Form Factor via Pseudo Entropy

Kavli Affiliate: Masahiro Nozaki | First 5 Authors: Kanato Goto, Masahiro Nozaki, Kotaro Tamaoka, , | Summary: We introduce a subsystem generalization of the spectral form factor via pseudo entropy, the von-Neumann entropy for the reduced transition matrix. We consider a transition matrix between the thermofield double state and its time-evolved state in two-dimensional conformal […]
