Backreaction Issues in Axion Monodromy and Minkowski 4-forms [PDF]
, 2017 We clarify the differences between the usual Kaloper-Sorbo description of axion monodromy and the effective axionic potential in terms of Minkowski 4-forms derived in string compactifications.

Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures
Advanced Engineering Materials, EarlyView.We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...

Superstring amplitudes, unitarily, and Hankel determinants of multiple zeta values
Journal of High Energy Physics, 2019 The interplay of unitarity and analyticity has long been known to impose strong constraints on scattering amplitudes in quantum field theory and string theory. This has been highlighted in recent times in a number of papers and lecture notes.

The Regge limit of AdS3 holographic correlators
Journal of High Energy Physics, 2020 We study the Regge limit of 4-point AdS3 × S 3 correlators in the tree-level supergravity approximation and provide various explicit checks of the relation between the eikonal phase derived in the bulk picture and the anomalous dimensions of certain ...

The Effective Theory of Strings [PDF]
Communications in Mathematical Physics, 2014 We show that the Nambu-Goto string, and its higher dimensional generalizations, can be quantized, in the sense of an effective theory, in any dimension of the target space. The crucial point is to consider expansions around classical string configurations.

The enhancon mechanism in string theory [PDF]
, 2002 The enhancon mechanism is a specific phenomenon in string theory which resolves a certain naked spacetime singularity arising in the supergravity description related to N = 2 supersymmetric pure gauge theory.
Järv, Laur
core
Advanced Engineering Materials, EarlyView.This article presents an experimental and numerical modal investigation of composite sandwich structures using surfboards as model systems. By comparing different core materials and reinforcement strategies, the study demonstrates how local stiffeners influence vibrational response and introduce characteristic modal features, highlighting modal ...

Holographic RG flows and Janus solutions from matter-coupled $$N=4$$ N = 4 gauged supergravity
European Physical Journal C: Particles and Fields, 2021 We study an $$SO(2)\times SO(2)\times SO(2)\times SO(2)$$ S O ( 2 ) × S O ( 2 ) × S O ( 2 ) × S O ( 2 ) truncation of four-dimensional $$N=4$$ N = 4 gauged supergravity coupled to six vector multiplets with $$SO(4)\times SO(4)$$ S O ( 4 ) × S O ( 4 ...

New supersymmetric $$AdS_5$$ A d S 5 black strings from 5D $$N=4$$ N = 4 gauged supergravity
European Physical Journal C: Particles and Fields, 2023 We find a large class of new supersymmetric $$AdS_5$$ A d S 5 black strings from five-dimensional $$N=4$$ N = 4 gauged supergravity coupled to five vector multiplets with $$SO(2)_D\times SO(3)\times SO(3)$$ S O ( 2 ) D × S O ( 3 ) × S O ( 3 ) gauge group.
