Two-nucleon electromagnetic current in chiral effective field theory: one-pion exchange and short-range contributions
S. Koelling, E. Epelbaum, H. Krebs +1
We derive the leading one-loop contribution to the one-pion exchange and short-range two-nucleon electromagnetic current operator in the framework of chiral effective field theory.…
Nuclear Spin-Depleted, Isotopically Enriched 70Ge/28Si70Ge Quantum Wells
O. Moutanabbir, S. Assali, A. Attiaoui +6
The p-symmetry of the hole wavefunction is associated with a weaker hyperfine interaction as compared to electrons, thus making hole spin qubits attractive candidates to implement…
Nuclear spin-free 70Ge/28Si70Ge quantum well heterostructures grown on industrial SiGe-buffered wafers
P. Daoust, N. Rotaru, D. Biswas +9
The coherence of hole spin qubits in germanium planar heterostructures is limited by the hyperfine coupling to the nuclear spin bath due to 29Si and 73Ge isotopes. Thus, removing t…
High-Bandwidth Extended-SWIR GeSn Photodetectors on Silicon Achieving Ultrafast Broadband Spectroscopic Response
M. R. M. Atalla, S. Assali, S. Koelling +2
The availability of high-frequency pulsed emitters in the m wavelength range paved the way for a wealth of new applications in ultrafast spectroscopy, free-space and fib…
Spin-orbit interaction and induced superconductivity in an one-dimensional hole gas
F. K. de Vries, J. Shen, R. J. Skolasinski +11
Low dimensional semiconducting structures with strong spin-orbit interaction (SOI) and induced superconductivity attracted much interest in the search for topological superconducto…
Two-pion exchange electromagnetic current in chiral effective field theory using the method of unitary transformation
S. Koelling, E. Epelbaum, H. Krebs +1
We derive the leading two-pion exchange contributions to the two-nucleon electromagnetic current operator in the framework of chiral effective field theory using the method of unit…
