When is an area law not an area law?
Anushya Chandran, Chris Laumann, Rafael D. Sorkin
Entanglement entropy is typically proportional to area, but sometimes it acquires an additional logarithmic pre-factor. We offer some intuitive explanations for these facts.
QCD Breaks Lorentz Invariance and Colour
A. P. Balachandran
In a previous work [1], we have argued that the algebra of non-abelian superselection rules is spontaneously broken to its maximal abelian subalgebra, that is, the algebra generate…
Maximally supersymmetric Yang-Mills on the lattice
David Schaich, Simon Catterall
We summarize recent progress in lattice studies of four-dimensional N=4 supersymmetric Yang--Mills theory and present preliminary results from ongoing investigations. Our work is b…
Early Universe Cosmology, Effective Supergravity, and Invariants of Algebraic Forms
Kuver Sinha
The presence of light scalars can have profound effects on early universe cosmology, influencing its thermal history as well as paradigms like inflation and baryogenesis. Effective…
Cosmological Moduli and the Post-Inflationary Universe: A Critical Review
Gordon Kane, Kuver Sinha, Scott Watson
We critically review the role of cosmological moduli in determining the post-inflationary history of the universe. Moduli are ubiquitous in string and M-theory constructions of bey…
Supersymmetry: Boundary Conditions and Edge States
Nirmalendu Acharyya, Manuel Asorey, A. P. Balachandran +1
When spatial boundaries are inserted, SUSY can be broken. We show that in an supersymmetric theory, all the boundary conditions allowed by self-adjointness of the H…
