The 2PI effective theory at next-to-leading order using the functional renormalization group
M. E. Carrington, S. A. Friesen, B. A. Meggison +3
We consider a symmetric scalar theory with quartic coupling in 4-dimensions. We show that the 4 loop 2PI calculation can be done using a renormalization group method. The calculati…
The role of frequency dependence in dynamical gap generation in graphene
M. E. Carrington, C. S. Fischer, L. von Smekal +1
We study the frequency dependencies of the fermion and photon dressing functions in dynamical gap generation in graphene. We use a low energy effective QED-like description, but wi…
Phase Diagram of Stability for Massive Scalars in Anti-de Sitter Spacetime
Brad Cownden, Nils Deppe, Andrew R. Frey
We diagram the behavior of 5-dimensional anti-de Sitter spacetime against horizon formation in the gravitational collapse of a scalar field, treating the scalar field mass and widt…
Mass-15 nuclei and predicting narrow states beyond the proton drip line
P. R. Fraser, K. Amos, L. Canton +3
In a previous letter (Phys. Rev. Lett. 96, 072502 (2006)), the multi-channel algebraic scattering (MCAS) technique was used to calculate spectral properties for proton-unstable $^{…
Exact time-dependent states for throat quantized toroidal AdS black holes
Hideki Maeda, Gabor Kunstatter
We investigate exact non-stationary quantum states of vacuum toroidal black holes with a negative cosmological constant in arbitrary dimensions using the framework of throat quanti…
