Consistency conditions for O-plane unsmearing from second-order perturbation theory
Maxim Emelin
Scale-separated AdS compactifications of string theory can be constructed at the two-derivative supergravity level in the presence of smeared orientifold planes. The unsmearing cor…
A note on integrability loss in fuzzball geometries
Maxim Emelin, Stefano Massai
We study the dynamics of certain string configurations in a class of fivebrane supertube backgrounds. In the decoupling limit of the fivebranes, these solutions are known to admit…
Obstacles for dS in Supersymmetric Theories
Maxim Emelin
We present two types of obstacles for constructing de Sitter space in supersymmetric theories that appear as effective theories of quantum gravity. The first obstacle concerns de S…
Anti-brane uplift instability from goldstino condensation
Gianguido Dall'Agata, Maxim Emelin, Fotis Farakos +1
We investigate the possible appearance of composite states of the goldstino in models with four-dimensional non-linear supersymmetry and we provide a description of their dynamics…
O6-plane backreaction on scale-separated Type IIA AdS vacua
Maxim Emelin, Fotis Farakos, George Tringas
We evaluate the backreaction of O6-planes in scale-separated flux vacua of massive Type IIA. Using the appropriate flux scaling we show that the corrections to the v…
The unbearable lightness of charged gravitini
Gianguido Dall'Agata, Maxim Emelin, Fotis Farakos +1
We prove that charged gravitini cannot have parametrically small or vanishing Lagrangian mass in de Sitter vacua of extended supergravity while respecting the magnetic weak gravity…
Three-dimensional flux vacua from IIB on co-calibrated G2 orientifolds
Maxim Emelin, Fotis Farakos, George Tringas
We derive the 3D N=1 superpotential for the closed string sector of type IIB supergravity on toroidal O5 orientifolds with co-calibrated G2 structure and RR background flux. We fin…
Effective Theories as Truncated Trans-Series and Scale Separated Compactifications
Maxim Emelin
We study the possibility of realizing scale-separated type IIB Anti-de Sitter and de Sitter compactifications within a controlled effective field theory regime defined by low-energ…
de Sitter Vacua in the String landscape: La Petite Version
Keshav Dasgupta, Maxim Emelin, Mir Mehedi Faruk +1
In this review we argue that four-dimensional effective field theory descriptions with de Sitter isometries are allowed in the presence of time-dependent internal degrees of freedo…
How a four-dimensional de Sitter solution remains outside the swampland
Keshav Dasgupta, Maxim Emelin, Mir Mehedi Faruk +1
We argue that, in the presence of time-dependent fluxes and quantum corrections, four-dimensional de Sitter solutions should appear in the type IIB string landscape and not in the…
de Sitter Vacua in the String Landscape
Keshav Dasgupta, Maxim Emelin, Mir Mehedi Faruk +1
The late-time behavior of our universe is one of accelerated expansion, or that of a de Sitter space, and therefore motivates us to look for time-dependent backgrounds. Finding suc…
Axion Hilltops, Kahler Modulus Quintessence and the Swampland Criteria
Maxim Emelin, Radu Tatar
We study the interplay between extrema of axion potentials, Kahler moduli stabilization and the swampland criteria. We argue that moving away from the minima of non-perturbatively…
Quantum Corrections and the de Sitter Swampland Conjecture
Keshav Dasgupta, Maxim Emelin, Evan McDonough +1
Recently a swampland criterion has been proposed that rules out de Sitter vacua in string theory. Such a criterion should hold at all points in the field space and especially at po…
Non-Kahler Deformed Conifold, Ultra-Violet Completion and Supersymmetric Constraints in the Baryonic Branch
Keshav Dasgupta, Jake Elituv, Maxim Emelin +1
Gravity duals for a class of UV complete minimally supersymmetric non-conformal gauge theories require deformed conifolds with fluxes. However these manifolds do not allow for the…
Renormalization Group Flow, Stability, and Bulk Viscosity in a Large N Thermal QCD Model
Keshav Dasgupta, Maxim Emelin, Charles Gale +1
The ultraviolet completion of a large N QCD model requires introducing new degrees of freedom at certain scale so that the UV behavior may become asymptotically conformal with no L…
Fermions on the Anti-Brane: Higher Order Interactions and Spontaneously Broken Supersymmetry
Keshav Dasgupta, Maxim Emelin, Evan McDonough
It has been recently argued that inserting a probe anti-D3-brane in a flux background breaks supersymmetry spontaneously instead of explicitly, as previously thought. In this paper…
Non-Kahler Resolved Conifold, Localized Fluxes in M-Theory and Supersymmetry
Keshav Dasgupta, Maxim Emelin, Evan McDonough
The known supergravity solution for wrapped D5-branes on the two-cycle of a Kahler resolved conifold is in general ISD but not supersymmetric, with the supersymmetry being broken b…
