Higher-Loop Vacuum Integrals on
Varun Lochab, Frederik Denef
We develop a new framework for evaluating higher-loop integrals for scalar fields on . Starting from a Schwinger-parametric form for general higher-loop integrals on the spher…
De Sitter Observers and an Effective Field Theory of Horizon Edge Modes
James Bonifacio, Kurt Hinterbichler, Y. T. Albert Law +1
We show that choosing a test observer in , specified by the framed embedding of their horizon , spontaneously breaks the de Sitter and internal sphere isometries to…
Horizon Edge Partition Functions in Quantum Gravity
Y. T. Albert Law, Varun Lochab
We obtain the spectra of codimension-2 horizon "edge" degrees of freedom for gravity and higher-spin gauge fields in de Sitter space and in the static Nariai spacetime, advancing p…
Gravitons on Nariai Edges
Y. T. Albert Law, Varun Lochab
We show that, for any , the one-loop graviton path integral on factorizes into bulk and edge parts. The bulk equals the thermal partition function of a…
High precision differential clock comparisons with a multiplexed optical lattice clock
Xin Zheng, Jonathan Dolde, Varun Lochab +3
Rapid progress in the precision and accuracy of optical atomic clocks over the last decade has advanced the frontiers of timekeeping, metrology, and quantum science. However, the s…
