Cyclic Inflation
Tirthabir Biswas, Stephon Alexander
We present an inflationary model that is geodesically complete and does not suffer from the transplanckian problem. In most inflationary models, massless (conformal) scalar field f…
Nonquantum Gravity
Stephen Boughn
One of the great challenges for 21st century physics is to quantize gravity and generate a theory that will unify gravity with the other three fundamental forces of nature. This pa…
A Partial Ordering on Slices of Planar Lagrangians
Phil Eiseman, Jonathan D. Lima, Joshua M. Sabloff +1
A collection of simple closed curves in $\rr^3$ is called a negative slice if it is the intersection of a flat-at-infinity planar Lagrangian surface and for some $a…
Obstructions to the Existence and Squeezing of Lagrangian Cobordisms
Joshua M. Sabloff, Lisa Traynor
Capacities that provide both qualitative and quantitative obstructions to the existence of a Lagrangian cobordism between two -dimensional submanifolds in parallel hyperplan…
The cosmological BCS mechanism and the Big Bang Singularity
Stephon Alexander, Tirthabir Biswas
We provide a novel mechanism that resolves the Big Bang Singularity present in FRW space-times without the need for ghost fields. Building on the fact that a four-fermion interacti…
Quantum gravity as a Fermi liquid
Stephon H. S. Alexander, Gianluca Calcagni
We present a reformulation of loop quantum gravity with a cosmological constant and no matter as a Fermi-liquid theory. When the topological sector is deformed and large gauge symm…
