D7-Brane Moduli Space in Axion Monodromy and Fluxbrane Inflation
Maximilian Arends, Arthur Hebecker, Konrad Heimpel +5
We analyze the quantum-corrected moduli space of D7-brane position moduli with special emphasis on inflationary model building. D7-brane deformation moduli are key players in two r…
D7-Brane Chaotic Inflation
Arthur Hebecker, Sebastian C. Kraus, Lukas T. Witkowski
We analyze string-theoretic large-field inflation in the regime of spontaneously-broken supergravity with conventional moduli stabilization by fluxes and non-perturbative effects.…
Evading the Lyth Bound in Hybrid Natural Inflation
Arthur Hebecker, Sebastian C. Kraus, Alexander Westphal
Generically, the gravitational-wave or tensor-mode contribution to the primordial curvature spectrum of inflation is tiny if the field-range of the inflaton is much smaller than th…
Fluxbranes: Moduli Stabilisation and Inflation
Arthur Hebecker, Sebastian C. Kraus, Moritz Kuntzler +2
Fluxbrane inflation is a stringy version of D-term inflation in which two fluxed D7-branes move towards each other until their (relative) gauge flux annihilates. Compared to brane-…
Fluxbrane Inflation
Arthur Hebecker, Sebastian C. Kraus, Dieter Lust +2
As a first step towards inflation in genuinely F-theoretic setups, we propose a scenario where the inflaton is the relative position of two 7-branes on holomorphic 4-cycles. Non-su…
Phase structure of the massive chiral Gross-Neveu model from Hartree-Fock
Christian Boehmer, Ulf Fritsch, Sebastian Kraus +1
The phase diagram of the massive chiral Gross-Neveu model (the massive Nambu-Jona-Lasinio model in 1+1 dimensions) is constructed. In the large N limit, the Hartree-Fock approach c…
