Emergent Spin Supersolids in Frustrated Quantum Materials

Advanced Materials, EarlyView.
This review highlights developments in the study of spin super‐solids in frustrated quantum materials. Advanced experimental characterizations and computational studies enable a comprehensive understanding of the driving mechanisms of spin super‐solidity in various layered transition‐metal compounds, bridging materials, experiments, and theory aspects.

Excited state calculations in solids by auxiliary-field quantum Monte Carlo

New Journal of Physics, 2013
We present an approach for ab initio many-body calculations of excited states in solids. Using auxiliary-field quantum Monte Carlo, we introduce an orthogonalization constraint with virtual orbitals to prevent collapse of the stochastic Slater ...

Large‐Scale Determination of Frontier Orbital Energies of Disordered Small‐Molecule Organic Semiconductors Using Exciplex Emission Spectra

Advanced Materials, EarlyView.
ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of

Revised B(E3) transition rate and structure of the 3− level in 96Zr

Physics Letters B, 2019
The B(E3) transition strength from the 1897-keV, 3− level in 96Zr has been reevaluated from six high-statistics, independent data sets. The measured value of 42(3) W.u. is significantly lower than that adopted in recent compilations.

Magnetic DNA Origami Nanorotors

Advanced Materials, EarlyView.
Magnetic actuation is a powerful and broadly applicable actuation mechanism due to its programmability and compatibility with biological entities. Here we demonstrate magnetic DNA origami nanorotors (MADONAs) by assembling magnetic nanocubes on DNA origami.

Verification of the use of GEANT4 and MCNPX Monte Carlo Codes for Calculations of the Depth-Dose Distributions in Water for the Proton Therapy of Eye Tumours

Nukleonika, 2014
Verification of calculations of the depth-dose distributions in water, using GEANT4 (version of 4.9.3) and MCNPX (version of 2.7.0) Monte Carlo codes, was performed for the scatterer-phantom system used in the dosimetry measurements in the proton therapy

1.5 µm Emission Properties of Erbium‐Implanted Thin‐Film Lithium Niobate

Advanced Optical Materials, EarlyView.
Optically active Er3+ ions are incorporated into x‐cut lithium niobate on insulator utilising a focused ion‐beam implantation method capable of sub‐100 nm precision. The implanted regions exhibit telecom‐band emission, with a reduction in photoluminescence intensity and lifetime below 50 K, consistent with pyroelectric‐field effects in the host ...
