Klein Bottle Cosmology
Brian Greene, Daniel Kabat, Janna Levin +1
We explore a higher-dimensional universe that is a product of Minkowski space and the nonorientable Klein bottle. The topology explicitly breaks important symmetries, such as trans…

Compactification Without Orientation, or a Topological Scenario for Violation
Brian Greene, Daniel Kabat, Janna Levin +1
In higher dimensional theories, we often assume that the extra dimensions form an orientable space, perhaps with singularities. However, many physical theories are well-defined on…

Modular Hamiltonians for future-perturbed states
Xiaole Jiang, Daniel Kabat, Aakash Marthandan +1
We develop a perturbative understanding of the modular Hamiltonian for a 2D CFT, divided into left and right half-spaces, with a weak local perturbation inserted in the future wedg…
