(Pre-)Hilbert spaces in twistor quantization

, 2013
In twistor theory, the canonical quantization procedure, called twistor quantization, is performed with the twistor operators represented as \hat{Z}^{A}=Z^{A}(\in C) and \hat{\bar{Z}}_{A}=-\frac{\partial}{\partial Z^{A}}.

Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

Advanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Burns space and holography

Journal of High Energy Physics, 2023
We elaborate on various aspects of our top-down celestial holographic duality wherein the semiclassical bulk spacetime is a 4d asymptotically flat, self-dual Kähler geometry known as Burns space.

A weight two phenomenon for the moduli of rank one local systems on open varieties [PDF]

, 2007
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

Non-Abelian Tensor Multiplet Equations from Twistor Space

, 2014
We establish a Penrose-Ward transform yielding a bijection between holomorphic principal 2-bundles over a twistor space and non-Abelian self-dual tensor fields on six-dimensional flat space-time.

Synchrotron Radiation for Quantum Technology

Advanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

An Ode to the Penrose and Witten transforms in twistor space for 3D CFT

Journal of High Energy Physics
Here we discuss the construction of Sp(4; ℝ) invariant objects in the twistor space for three dimensional conformal field theories. The Sp(4; ℝ) invariant projective delta function, alongside the Twistor symplectic dot product invariants form the basis ...

Model of massless relativistic particle with continuous spin and its twistorial description

Journal of High Energy Physics, 2018
We propose a new world-line Lagrangian model of the D= 4 massless relativistic particle with continuous spin and develop its twistorial formulation. The description uses two Penrose twistors subjected to four first class constraints.

Twistors, the ASD Yang-Mills equations and 4d Chern-Simons theory

Journal of High Energy Physics, 2023
We show that the approaches to integrable systems via 4d Chern-Simons theory and via symmetry reductions of the anti-self-dual Yang-Mills equations are closely related, at least classically.

A Direct Proof of BCFW Recursion for Twistor-Strings

, 2010
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 ...
