Fundamental Properties of Heavily Ge‐Doped AlGaN Prepared via Pulsed Sputtering

open access: yesphysica status solidi (b), EarlyView.
This study explores the properties of heavily Ge‐doped AlGaN films prepared via pulsed sputtering deposition. Films with Al content below 34% exhibit higher electron concentrations than Si‐doped counterparts. The maximum carrier concentration reaches 1.8 × 1020 cm−3. Optical bandgaps are enhanced by the Burstein–Moss shift.

Toward Ultrawide Bandgap Engineering: Physical Properties of an α‐(TixGa1−x)2O3 Material Library

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
The material system α‐(TixGa1−x)2O3 has potential applications in optoelectronics as it theoretically offers a bandgap tunable over a wide range from 0.14 to 5.6 eV. In the present work, spatially addressable material libraries of (TixGa1−x)yOz are realized using combinatorial material synthesis.

Density Matrix Renormalization Group Lagrangians [PDF]

open access: yes, 2008
We introduce a Lagrangian formulation of the Density Matrix Renormalization Group (DMRG). We present Lagrangians which when minimised yield the optimal DMRG wavefunction in a variational sense, both within the general matrix product ansatz, as well as ...

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

open access: yesAdvanced Quantum Technologies, EarlyView.
The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...
