A new twist on spinning (A)dS correlators
Massless spinning correlators in cosmology are extremely complicated. In contrast, the scattering amplitudes of massless particles with spin are very simple.

Notes on scattering amplitudes as differential forms
Inspired by the idea of viewing amplitudes in N = 4 $$ \mathcal{N}=4 $$ SYM as differential forms on momentum twistor space, we introduce differential forms on the space of spinor variables, which combine helicity amplitudes in any four-dimensional gauge

Scattering amplitudes and BCFW recursion in twistor space [PDF]
Twistor ideas have led to a number of recent advances in our understanding of scattering amplitudes. Much of this work has been indirect, determining the twistor space support of scattering amplitudes by examining the amplitudes in momentum space.

A weight two phenomenon for the moduli of rank one local systems on open varieties [PDF]
The twistor space of representations on an open variety maps to a weight two space of local monodromy transformations around a divisor component at infinty. The space of $\sigma$-invariant sections of this slope-two bundle over the twistor line is a real

A Direct Proof of BCFW Recursion for Twistor-Strings
This paper gives a direct proof that the leading trace part of the genus zero twistor-string path integral obeys the BCFW recursion relation. This is the first complete proof that the twistor-string correctly computes all tree amplitudes in maximally ...

A high‐performance n‐type element for quasi‐solid‐state thermocells has been introduced, outperforming conventional p‐type elements and showcasing the potential to harness body heat as an energy source or power embedded sensors. This advance significantly contributes to waste thermal energy harvesting and wearable technology, paving the way for self ...

Cutting the traintracks: Cauchy, Schubert and Calabi-Yau
In this note we revisit the maximal-codimension residues, or leading singularities, of four-dimensional L-loop traintrack integrals with massive legs, both in Feynman parameter space and in momentum (twistor) space.

Towards a Complete Twistorization of the Heterotic String
In $D=3,4,6$ and 10 space--time dimensions considered is a string model invariant under transformations of $N=1$ space--time supersymmetry and $n=D-2$ local worldsheet supersymmetry with the both Virasoro constraints solved in the twistor form.

This review explores Zn anode challenges in aqueous ZIBs, including dendrites, corrosion, and side reactions, and discusses strategies for improvement through Zn anode, electrolyte, and separator modifications to enhance stability and efficiency. Abstract Aqueous rechargeable zinc‐ion batteries (ZIBs) are emerging as promising candidates for next ...

The holographic dual of the Penrose transform
We consider the holographic duality between type-A higher-spin gravity in AdS4 and the free U(N) vector model. In the bulk, linearized solutions can be translated into twistor functions via the Penrose transform.
