One-loop -adic string theory and the Néron local height function
An Huang, Christian Jepsen
The -adic string worldsheet action on the quotient of the Bruhat-Tits tree of by a genus 1 Schottky group has a dual description on the asymptotic boundary…
A glimpse into the Ultrametric spectrum
An Huang, Christian B. Jepsen
The non-relativistic string spectrum is built from integer-spaced energy quanta in such a way that the high-temperature asymptotics, via the Hardy-Ramanujan formula for integer par…
The Veneziano Amplitude in any Dimension and a Virasoro-Shapiro Partial Amplitude
Christian Baadsgaard Jepsen
This paper demonstrates how the Veneziano partial amplitude of bosonic string theory admits a generalization to world-(hyper)surfaces of any dimension . In particular, for …
Finite Temperature at Finite Places
An Huang, Christian Baadsgaard Jepsen
This paper studies AdS/CFT in its -adic version (at the ``finite place") in the setting where the bulk geometry is made up of the Tate curve, a discrete quotient of the Bruhat-T…
Extremal fixed points and Diophantine equations
Christopher P. Herzog, Christian B. Jepsen, Hugh Osborn +1
The coupling constants of fixed points in the expansion at one loop are known to satisfy a quadratic bound due to Rychkov and Stergiou. We refer to fixed points that saturate t…
Scattering on the Worldvolume: Amplitude Relations in Brower-Goddard String Models
N. Emil J. Bjerrum-Bohr, Christian Baadsgaard Jepsen
We investigate the Brower-Goddard extension of the Veneziano and Virasoro-Shapiro four-point amplitudes obtained by generalizing the Koba-Nielsen integrals to -dimensional confo…
