Dimensionally Resolved Nanostructures of an Atomically Precise and Optically Active 1D van der Waals Helix

Advanced Materials, EarlyView.
The ability to grow nanostructures based on inorganic helical crystals with long‐range order will enable a platform to realize physical states that arise from chirality. Herein, it is demonstrated that controlled vapor phase deposition of an atomically precise helical crystal, GaSI, into ultrathin 1D nanowires and quasi‐2D nanoribbons.

Multi-jet production in lepton-proton scattering at next-to-leading order accuracy

, 2005
I summarize the theoretical and experimental status of multijet production in DIS. I present the state of the art theoretical predictions and compare those to the corresponding experimental results obtained by analysing the data collected by the H1 and ...

Enhanced Self‐Phase Modulation in Silicon Nitride Waveguides Integrated With 2D MoS2 Films

Advanced Materials Technologies, EarlyView.
ABSTRACT On‐chip integration of 2D materials provides a promising route toward next‐generation integrated optical devices with performance beyond existing limits. Here, significantly enhanced spectral broadening induced by self‐phase modulation (SPM) is experimentally demonstrated in silicon nitride (Si3N4) waveguides integrated with 2D monolayer ...

Molecular Engineering for Enhanced Second‐Order Nonlinear Response in Spontaneously‐Oriented Evaporated Organic Films

Advanced Optical Materials, EarlyView.
Intramolecular bridge‐locking frustrates detrimental anti‐parallel packing in evaporated organic films. This design enhances net polar orientation, leading to a twofold off‐resonance increase in the second‐order nonlinear susceptibility (χ(2)) without electric‐field poling.

Two-loop amplitudes for Higgs plus jet production involving a modified trilinear Higgs coupling

Journal of High Energy Physics, 2019
We calculate the contributions to the two-loop scattering amplitudes h → gg, h → ggg and h → q q ¯ g $$ h\to q\overline{q}g $$ that arise from a modified trilinear Higgs coupling λ.

Two-loop QCD-EW master integrals for Z plus jet production at large transverse momentum

Journal of High Energy Physics, 2020
The production of electroweak Z bosons that decay to neutrinos and recoil against jets with large transverse momentum p ⊥ is an important background process to searches for dark matter at the Large Hadron Collider (LHC).

Subtraction at NNLO

, 2004
We propose a framework for the implementation of a subtraction formalism at NNLO in QCD, based on an observable- and process-independent cancellation of infrared singularities. As a first simple application, we present the calculation of the contribution
