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

open access: yesJournal 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.

Supersymmetric $$AdS_4$$ A d S 4 black holes from matter-coupled $$N=3,4$$ N = 3 , 4 gauged supergravities

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We study supersymmetric $$AdS_4$$ A d S 4 black holes in matter-coupled $$N=3$$ N = 3 and $$N=4$$ N = 4 gauged supergravities in four dimensions. In $$N=3$$ N = 3 theory, we consider $$N=3$$ N = 3 gauged supergravity coupled to three vector multiplets ...

String Theory Phenomenology

open access: yesJournal of Physics: Conference Series, 2006
We review the qualitative features of string theory compactifications with low energy effective theory close to (supersymmetric versions of) the Standard Model of Particle Physics. We cover Calabi-Yau compactifications of heterotic strings, intersecting brane models, and the recent setup of F-theory models.

Toughening β‐Ga2O3 via Mechanically Seeded Dislocations

open access: yesAdvanced Functional Materials, EarlyView.
β‐Ga2O3 is promising for next‐generation semiconductors but its brittleness limits flexible and high‐precision applications. Here, mechanically seeded dislocations introduced by surface deformation improved damage tolerance in (001) β‐Ga2O3. Nanoindentation and characterization show dislocations suppress cleavage cracks by enabling stable plastic ...

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

open access: yesJournal 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

Artificial Intelligence as the Next Visionary in Liquid Crystal Research

open access: yesAdvanced Functional Materials, EarlyView.
The functions of AI in the research laboratory are becoming increasingly sophisticated, allowing the entire process of hypothesis formulation, material design, synthesis, experimental design, and reiterative testing to be automated. In our work, we conceive how the incorporation of AI in the laboratory environment will transform the role and ...

String field theory

open access: yes, 2009
This elementary introduction to string field theory highlights the features and the limitations of this approach to quantum gravity as it is currently understood. String field theory is a formulation of string theory as a field theory in space-time with an infinite number of massive fields. Although existing constructions of string field theory require

In Vivo Skin 3‐D Surface Reconstruction and Wrinkle Depth Estimation Using Handheld High Resolution Tactile Sensing

open access: yesAdvanced Healthcare Materials, EarlyView.
A compact handheld GelSight probe reconstructs in vivo 3‐D skin topography with micron‐level precision using a custom elastic gel and a learning‐based surface normal to height map pipeline. The device quantifies wrinkle depth across various body locations and detects changes in wrinkle depth following moisturizer application.

The Kerr-Schild double copy in curved spacetime

open access: yesJournal 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.

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

open access: yesAdvanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...
