Exotic branes in Exceptional Field Theory: E 7(7) and beyond

Journal of High Energy Physics, 2018
In recent years, it has been widely argued that the duality transformations of string and M-theory naturally imply the existence of so-called ‘exotic branes’ — low codimension objects with highly non-perturbative tensions, scaling as g s α for α ≤ −3. We

Some Recent Progress in AdS/CFT

, 2010
Much of modern string theory research concerns AdS/CFT duality, or more generally, gauge/gravity duality. The main subjects are a) Testing and understanding such dualities by exploring how they work for systems with a lot of supersymmetry b) Constructing

Manipulating Ferroelectric Topological Polar Structures with Twisted Light

Advanced Materials, EarlyView.
We demonstrate dynamic control of ferroelectric order in quasi‐2D CsBiNb2O7 using twisted ultraviolet light carrying orbital angular momentum. Our approach harnesses non‐resonant multiphoton absorption and induced strain to modulate topological of ferroelectric polarization textures.

The Kerr-Schild double copy in curved spacetime

Journal of High Energy Physics, 2017
The double copy is a much-studied relationship between scattering amplitudes in gauge and gravity theories, that has subsequently been extended to classical field solutions.

Comment about UV regularization of basic commutators in string theories [PDF]

, 1998
Recently proposed by Hwang, Marnelius and Saltsidis zeta regularization of basic commutators in string theories is generalized to the string models with non-trivial vacuums.

Recent Advances in Stimuli‐Responsive Materials and Soft Robotic Actuators for Bioelectronic Medicine

Advanced Materials, EarlyView.
This review explores the integration of responsive materials and soft robotic actuators with implantable electronics to address key challenges in bioelectronic medicine. By enabling shape actuation, these technologies improve deployment, adaptability, and accuracy in minimally invasive procedures.

On next-to-leading power threshold corrections in Drell-Yan production at N3LO

Journal of High Energy Physics, 2018
The cross-section for Drell-Yan production of a vector boson has been previously calculated at next-to-next-to-leading order, supplemented by enhanced logarithmic terms associated with the threshold region.

Bounds on masses of bulk fields in string compactifications

, 2006
In string compactification on a manifold X, in addition to the string scale and the normal scales of low-energy particle physics, there is a Kaluza-Klein scale 1/R associated with the size of X.

Tilted String Cosmologies [PDF]

, 1999
Global symmetries of the string effective action are employed to generate tilted, homogeneous Bianchi type VI_h string cosmologies from a previously known stiff perfect fluid solution to Einstein gravity. The dilaton field is not constant on the surfaces

Gravitational waves from cosmic strings in LISA: reconstruction pipeline and physics interpretation [PDF]

Journal of Cosmology and Astroparticle Physics
We initiate the LISA template databank for stochastic gravitational wave backgrounds sourced by cosmic strings. We include two templates, an analytical template, which enables more flexible searches, and a numerical template derived directly from large ...
