Ballistic electron spectroscopy

, 2006
We demonstrate the feasibility of ballistic electron spectroscopy as a new tool for mesoscopic physics. A quantum dot is utilised as an energy-selective detector of non-equilibrium ballistic electrons injected into a two-dimensional electron system.

Synchrotron‐generated microbeams as a radiosurgical alternative for drug‐resistant epilepsies: Proof of concept in a mouse model of mesiotemporal lobe epilepsy

Epilepsia, EarlyView.
Abstract Objective One‐third of patients with epilepsy, particularly those with mesial temporal lobe epilepsy (MTLE), remain resistant to medication. Resective surgery, the gold standard, is highly invasive and carries significant risks. Here, using a mouse model, we explored the potential of microbeam radiation therapy (MRT), a new technique based on ...

Turbulent pair dispersion in the presence of gravity

New Journal of Physics, 2015
Turbulent pair dispersion of heavy particles is strongly altered when particles of two different Stokes numbers (bidisperse) are considered, and this is further compounded when a uniform gravitational acceleration is present.

Computational design of two‐dimensional MA2Z4 family field‐effect transistor for future Ångström‐scale CMOS technology nodes

InfoMat, EarlyView.
Two‐dimensional MA2Z4 such as MoSi2N4 offer a new path to extend transistor scaling beyond the limits of silicon. Due to their exceptional properties, these 2D semiconductors are promising candidates for future Ångström‐scale CMOS technology. This review outlines the computational design and roadmap bridging materials discovery, device design and ...

Driving quantum walk spreading with the coin operator

, 2009
We generalize the discrete quantum walk on the line using a time dependent unitary coin operator. We find an analytical relation between the long-time behaviors of the standard deviation and the coin operator.

Construction and Evaluation of a Ballistic Gelatin‐Based Simulator for Transcervical Chorionic Villus Sampling

Journal of Ultrasound in Medicine, EarlyView.
Chorionic villus sampling (CVS) is a crucial prenatal diagnostic tool, but a declining number of procedures makes training a challenge. Here we describe a transcervical CVS simulator made from ballistic gelatin. Ninety‐three Maternal‐Fetal Medicine providers used the simulators during hands‐on workshops and completed surveys regarding their fidelity ...

Inverse Design of Mirror‐Symmetric Disordered Systems for Broadband Perfect Transmission

Laser &Photonics Reviews, EarlyView.
This work introduces an inverse design approach to achieve broadband perfect wave transmission in mirror‐symmetric disordered media. Leveraging symmetry simplifies optimization and enables control of multiple reflectionless states. Experiments in microwave waveguides confirm the design of exceptional points, bandpass filters, and broadband quasi ...

Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials

Laser &Photonics Reviews, EarlyView.
This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...

Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems

Laser &Photonics Reviews, EarlyView.
This work demonstrates that ultrathin rubidium vapor cells can emulate atomic‐beam behavior through geometry‐dependent velocity filtering. Employing a spatially separated pump–probe scheme and Faraday–Ramsey rotation, the study reveals coherent atomic dynamics without buffer gas or anti‐relaxation coatings. This approach offers a compact pathway toward
