On Instanton Superpotentials, Calabi-Yau Geometry, and Fibrations

Lara B. Anderson, Fabio Apruzzi, Xin Gao +2

In this paper we explore contributions to non-perturbative superpotentials arising from instantons wrapping effective divisors in smooth Calabi-Yau four-folds. We concentrate on th…

Grassmann Matrix Quantum Mechanics

Dionysios Anninos, Frederik Denef, Ruben Monten

We explore quantum mechanical theories whose fundamental degrees of freedom are rectangular matrices with Grassmann valued matrix elements. We study particular models where the low…

F-theory and the Classification of Little Strings

Lakshya Bhardwaj, Michele Del Zotto, Jonathan J. Heckman +3

Little string theories (LSTs) are UV complete non-local 6D theories decoupled from gravity in which there is an intrinsic string scale. In this paper we present a systematic approa…

No-go for Partially Massless Spin-2 Yang-Mills

Sebastian Garcia-Saenz, Kurt Hinterbichler, Austin Joyce +2

There are various no-go results forbidding self-interactions for a single partially massless spin-2 field. Given the photon-like structure of the linear partially massless field, i…

Perturbations of vortex ring pairs

Steven S. Gubser, Bart Horn, Sarthak Parikh

We study pairs of co-axial vortex rings starting from the action for a classical bosonic string in a three-form background. We complete earlier work on the phase diagram of classic…

Axionic Band Structure of the Cosmological Constant

Thomas C. Bachlechner

We argue that theories with multiple axions generically contain a large number of vacua that can account for the smallness of the cosmological constant. In a theory with N axions,…

Massive quiver matrix models for massive charged particles in AdS

Curtis T. Asplund, Frederik Denef, Eric Dzienkowski

We present a new class of supersymmetric quiver matrix models and argue that it describes the stringy low-energy dynamics of internally wrapped D-branes in four-dimens…

Platonic solids back in the sky: Icosahedral inflation

Jonghee Kang, Alberto Nicolis

We generalize the model of solid inflation to an anisotropic cosmic solid. Barring fine tunings, the observed isotropy of the cosmological background and of the scalar two-point fu…

Flux Formulation of DFT on Group Manifolds and Generalized Scherk-Schwarz Compactifications

Pascal du Bosque, Falk Hassler, Dieter Lust

A flux formulation of Double Field Theory on group manifold is derived and applied to study generalized Scherk-Schwarz compactifications, which give rise to a bosonic subsector of…

Segmented Strings in

Nele Callebaut, Steven S. Gubser, Andreas Samberg +1

We study segmented strings in flat space and in . In flat space, these well known classical motions describe strings which at any instant of time are piecewise linear. In $A…

Effective string theory for vortex lines in fluids and superfluids

Bart Horn, Alberto Nicolis, Riccardo Penco

We discuss the effective string theory of vortex lines in ordinary fluids and low-temperature superfluids, by describing the bulk fluid flow in terms of a two-form field to which v…

Energy loss, equilibration, and thermodynamics of a baryon rich strongly coupled quark-gluon plasma

Romulo Rougemont, Andrej Ficnar, Stefano Finazzo +1

Lattice data for the QCD equation of state and the baryon susceptibility near the crossover phase transition (at zero baryon density) are used to determine the input parameters of…

Partially Massless Monopoles and Charges

Kurt Hinterbichler, Rachel A. Rosen

Massive higher spin fields on de Sitter space exhibit enhanced gauge symmetries at special values of the mass. These fields are known as "partially massless." We study the structur…

Vanishing DC holographic conductivity from a magnetic monopole condensate

Romulo Rougemont, Jorge Noronha, Carlos A. D. Zarro +3

We show how to obtain a vanishing DC conductivity in 3-dimensional strongly coupled QFT's using a massive 2-form field in the bulk that satisfies a special kind of boundary conditi…

Entanglement Scrambling in 2d Conformal Field Theory

Curtis T. Asplund, Alice Bernamonti, Federico Galli +1

We investigate how entanglement spreads in time-dependent states of a 1+1 dimensional conformal field theory (CFT). The results depend qualitatively on the value of the central cha…

Holographic calculation of the QCD crossover temperature in a magnetic field

Romulo Rougemont, Renato Critelli, Jorge Noronha

Lattice data for the QCD equation of state and the magnetic susceptibility computed near the crossover transition at zero magnetic field are used to determine the input parameters…

Entanglement entropy converges to classical entropy around periodic orbits

Curtis T. Asplund, David Berenstein

We consider oscillators evolving subject to a periodic driving force that dynamically entangles them, and argue that this gives the linearized evolution around periodic orbits in a…

A Note on Ghost-Free Matter Couplings in Massive Gravity and Multi-Gravity

Kurt Hinterbichler, Rachel A. Rosen

We consider a recently proposed non-minimal matter coupling in massive gravity and multi-gravity. We argue that, when formulated in terms of unconstrained vielbeins, this matter co…

Lagrangian space consistency relation for large scale structure

Bart Horn, Lam Hui, Xiao Xiao

Consistency relations, which relate the squeezed limit of an (N+1)-point correlation function to an N-point function, are non-perturbative symmetry statements that hold even if the…

Higher Order Deformations of Complex Structures

Eric D'Hoker, Duong H. Phong

Deformations of complex structures by finite Beltrami differentials are considered on general Riemann surfaces. Exact formulas to any fixed order are derived for the corresponding…

The Super Period Matrix with Ramond Punctures in the supergravity formulation

Eric D'Hoker, Duong H. Phong

In a very recent preprint, Witten showed how to construct a super period matrix for super Riemann surfaces of genus with Ramond punctures, which is…
