D7-brane chaotic inflation

Physics Letters B, 2014
We analyze string-theoretic large-field inflation in the regime of spontaneously-broken supergravity with conventional moduli stabilization by fluxes and non-perturbative effects. The main ingredient is a shift-symmetric Kähler potential, supplemented by

"Big" Divisor D3/D7 Swiss Cheese Phenomenology [PDF]

Modern Physics Letters A, 2010
We review progress made over the past couple of years in the field of Swiss Cheese Phenomenology involving a mobile space-time filling D3-brane and stack(s) of fluxed D7-branes wrapping the "big" (as opposed to the "small") divisor in (the orientifold of

Superconductivity from D3/D7: Holographic Pion Superfluid [PDF]

Journal of High Energy Physics, 2008
We show that a D3/D7 system (at zero quark mass limit) at finite isospin chemical potential goes through a superconductor (superfluid) like phase transition.

D7 moduli stabilization: the tadpole menace [PDF]

Journal of High Energy Physics, 2022
Abstract D7-brane moduli are stabilized by worldvolume fluxes, which contribute to the D3-brane tadpole. We calculate this contribution in the Type IIB limit of F-theory compactifications on Calabi-Yau four-folds with a weak Fano base, and are able to prove a no-go theorem for vast swathes of the landscape of compactifications ...

Monodromy charge in D7-brane inflation [PDF]

Journal of High Energy Physics, 2020
AbstractIn axion monodromy inflation, traversingNaxion periods corresponds to dischargingNunits of a quantized charge. In certain models with moving D7-branes, such as Higgs-otic inflation, this monodromy charge is D3-brane charge induced on the D7-branes.

D7–anti-D7 bilayer: Holographic dynamical symmetry breaking

Physics Letters B, 2013
We consider a holographic model of dynamical symmetry breaking in 2+1-dimenisons, where a parallel D7-anti-D7 brane pair fuse into a single object, corresponding to the U(1)XU(1)->U(1) symmetry breaking pattern. We show that the current-current correlation functions can be computed analytically and exhibit the low momentum structure that is expected

On the D(–1)/D7-brane systems [PDF]

Journal of High Energy Physics, 2021
Abstract We study non-perturbative effects in supersymmetric U(N) gauge theories in eight dimensions realized by means of D(–1)/D7-brane systems with non-trivial world-volume fluxes turned on. Using an explicit string construction in terms of vertex operators, we derive the action for the open strings ending on the D(–1)-branes and

Swiss-cheese D3–D7 soft SUSY breaking [PDF]

Nuclear Physics B, 2010
In type IIB large volume compactifications involving orientifolds of the Swiss-Cheese Calabi-Yau [11169] with a single mobile space-time filling D3-brane and stacks of D7-branes wrapping the "big" divisor (D_5) and supporting D7-brane fluxes, (i) using the toric data and GLSM techniques, we obtain the geometric Kaehler potential for D_5 in terms of ...

D-terms and F-terms from D7-brane fluxes [PDF]

, 2005
Using a Kaluza-Klein reduction of the fermionic part of the D-brane action we compute D- and F-terms of the N=1 effective action for generic Calabi-Yau orientifold compactifications in the presence of a space-time filling D7-brane. We include non-trivial

Toward a cognitive science of markets: economic agents as sense-makers

Economics: Journal Articles, 2019
Behavioral economics aspires to replace the agents of neoclassical economics with living, breathing human beings. Here, the author argues that behavioral economics, like its neoclassical counterpart, often neglects the role of active sense-making that ...
