Nuclear density functional constrained by low-energy QCD

Paolo Finelli, Norbert Kaiser, Dario Vretenar +1

We have developed a relativistic point-coupling model of nuclear many-body dynamics constrained by the low-energy sector of QCD. The effective Lagrangian is characterized by densit…

Modulating the growth conditions: Si as an acceptor in (110) GaAs for high mobility p-type heterostructures

F. Fischer, M. Grayson, D. Schuh +2

We implement metallic layers of Si-doped (110) GaAs as modulation doping in high mobility p-type heterostructures, changing to p-growth conditions for the doping layer alone. The s…

Extraction of m_s and |V_us| from Hadronic Tau Decays

Elvira Gamiz, Matthias Jamin, Antonio Pich +2

We review recent work to determine the strange quark mass m_s as well as the proposal to determine |V_{us}| using hadronic tau decay data. The recent update of the strange spectral…
