Semiclassical Gravity Efficiently Solves -Complete Problems
Matthew Fox, Chaitanya Karamchedu, Sotirios Mygdalas
Assuming the gravitational field is classical and that it couples to quantum fields via the semiclassical Einstein field equations, we show that the weak-field dynamics of a massiv…

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…
