The free boundary problem in general relativity
Kostas Tzanavaris, Latham Boyle, Neil Turok
We study the action principle for space-times whose boundary is singular. We suggest that it is natural to treat the singularity as a {\it free} boundary, where the variation is un…
Spacetime Quasicrystals
Latham Boyle, Sotirios Mygdalas
Self-similar quasicrystals (like the famous Penrose and Ammann-Beenker tilings) are exceptional geometric structures in which long-range order, quasiperiodicity, non-crystallograph…
-Symmetric Kähler-Dirac Fermions
Latham Boyle, Wei-Ning Deng
Kähler-Dirac (KD) spinors have generated excitement in the lattice gauge theory community, as a way to (i) deal with the ``fermion doubling" problems that plague ordinary (Dirac, M…
On Interstellar Quantum Communication and the Fermi Paradox
Latham Boyle
Since it began \cite{CocconiMorrison}, the search for extraterrestrial intelligence (SETI) has focused on interstellar \emph{classical} communication. Recently, Berera \cite{Berera…
