Comment on: "Does an atom interferometer test the gravitational redshift at the Compton frequency?"

Michael A. Hohensee, Steven Chu, Achim Peters +1

We show that Wolf et al.'s 2011 analysis in Class. Quant. Grav. v28, 145017 does not support their conclusions, in particular that there is "no redshift effect" in atom interferome…

Delay-enhanced coherent chaotic oscillations in networks with large disorders

D. V. Senthilkumar, R. Suresh, Jane H. Sheeba +2

We study the effect of coupling delay in a regular network with a ring topology and in a more complex network with an all-to-all (global) topology in the presence of impurities (di…

Four-loop anomalous dimensions in Leigh-Strassler deformations

J. A. Minahan, C. Sieg

We determine the scalar part of the four-loop chiral dilatation operator for Leigh-Strassler deformations of N=4 super Yang-Mills. This is sufficient to find the four-loop anomalou…

Synchronizability of networks with strongly delayed links: A universal classification

V. Flunkert, S. Yanchuk, T. Dahms +1

We show that for large coupling delays the synchronizability of delay-coupled networks of identical units relates in a simple way to the spectral properties of the network topology…

The three-loop form factor in N=4 super Yang-Mills

Thomas Gehrmann, Johannes M. Henn, Tobias Huber

In this paper we study the Sudakov form factor in N=4 super Yang-Mills theory to the three-loop order. The latter is expressed in terms of planar and non-planar loop integrals. We…
