A Mathematical Construction of an E6 Grand Unified Theory
Anthony Britto
Of the five exceptional groups, is considered the most attractive for unification due to the following reasons: (i) it contains both $\mathrm{Spin} (10) \times \math…
Free Fermions Violate the Area Law For Entanglement Entropy
Robert C. Helling, Wolfgang Spitzer
We show that the entanglement entropy associated to a region grows faster than the area of its boundary surface. This is done by proving a special case of a conjecture due to Widom…
Macroscopic Screening of Coulomb Potentials From UV/IR-Mixing
Robert C. Helling, Jiangyang You
We compute the static potential in a non-commutative theory including a term due to UV/IR-mixing. As a result, the potential decays exponentially fast with distance rather than lik…
Lessons from the LQG String
Robert C. Helling
We give a non-technical description of the differences of quantisation of the bosonic string between the usual Fock-space approach and the treatment inspired by methods of loop qua…
A note on the center of mass in non-commutative theories
Robert C. Helling
The dynamics of a stack of N D-branes is described by U(N) gauge theory of which the central U(1) describes the center of mass motion and the remaining SU(N) describes the internal…
String quantization: Fock vs. LQG Representations
Robert C. Helling, Giuseppe Policastro
We set up a unified framework to compare the quantization of the bosonic string in two approaches: One proposed by Thiemann, based on methods of loop quantum gravity, and the other…
