Mixed field theory
Steven S. Gubser, Christian Jepsen, Ziming Ji +1
We consider scalar field theory defined over a direct product of the real and -adic numbers. An adjustable dynamical scaling exponent enters into the microscopic lagrangian,…
Higher melonic theories
Steven S. Gubser, Christian Jepsen, Ziming Ji +1
We classify a large set of melonic theories with arbitrary -fold interactions, demonstrating that the interaction vertices exhibit a range of symmetries, always of the form $\ma…
Continuum limits of sparse coupling patterns
Steven S. Gubser, Christian Jepsen, Ziming Ji +1
We exhibit simple lattice systems, motivated by recently proposed cold atom experiments, whose continuum limits interpolate between real and -adic smoothness as a spectral expon…
