Pressure dependence of the charge-density-wave and superconducting states in GdTe 3 , TbTe 3 , and DyTe 3

Abstract: We present electrical resistivity and ac-susceptibility measurements of ${\text{GdTe}}_{3}, {\text{TbTe}}_{3}$, and ${\text{DyTe}}_{3}$ performed under pressure. An upper charge-density-wave (CDW) is suppressed at a rate of $d{T}_{\mathrm{CDW},1}/dP\ensuremath{\sim}\ensuremath{-}85\phantom{\rule{0.28em}{0ex}}\mathrm{K}/\mathrm{GPa}$. For ${\text{TbTe}}_{3}$ and ${\text{DyTe}}_{3}$, a second CDW below ${T}_{\mathrm{CDW},2}$ increases with pressure until it reaches the ${T}_{\mathrm{CDW},1}$($P$) line. For ${\text{GdTe}}_{3}$, the lower CDW emerges as pressure is increased above $\ensuremath{\sim}1\phantom{\rule{0.28em}{0ex}}\text{GPa}$. As these two CDW states are suppressed with pressure, superconductivity (SC) appears in the three compounds at lower temperatures. Ac-susceptibility experiments performed on ${\text{TbTe}}_{3}$ provide compelling evidence for bulk SC in the low-pressure region of the phase diagram. We provide measurements of superconducting critical fields and discuss the origin of a high-pressure superconducting phase occurring above 5 GPa.

Measurement of the neutrino asymmetry parameter B in neutron decay.

Abstract: A new measurement of the neutrino asymmetry parameter $B$ in neutron decay, the angular correlation between neutron spin and antineutrino momentum, is presented. The result, $B=0.9802(50)$, confirms earlier measurements but features considerably smaller corrections. It agrees with the standard model expectation and permits updated tests on ``new physics'' in neutron decay.

Molecular detection of Anaplasma phagocytophilum in the European hedgehog (Erinaceus europaeus) and its ticks.

Abstract: The European hedgehog (Erinaceus europaeus) is a common wild mammal in Central Europe that shares habitats with humans in urban, peri-urban, and rural areas. Thus, this species may play a role in human contact with zoonotic diseases. Here we report the presence of the pathogen Anaplasma phagocytophilum in hedgehogs and their ticks in Germany.
