Shot noise in a harmonically driven ballistic graphene transistor
Yevgeniy Korniyenko, Oleksii Shevtsov, Tomas Lofwander
We study time-dependent electron transport and quantum noise in a ballistic graphene field effect transistor driven by an ac gate potential. The non-linear response to the ac signa…
Suppressing relaxation in superconducting qubits by quasiparticle pumping
Simon Gustavsson, Fei Yan, Gianluigi Catelani +15
Dynamical error suppression techniques are commonly used to improve coherence in quantum systems. They reduce dephasing errors by applying control pulses designed to reverse errone…

We present high-resolution (1".0) Atacama Large Millimeter/submillimeter Array (ALMA) observations of CO (1-0) and CO (2- 1) rotational transitions toward the nearby IR-luminous me…
(sub)Millimeter Emission Lines of Molecules in Born-again Stars
D. Tafoya, J. A. Toalá, W. H. T. Vlemmings +7
The detection and study of molecular gas in born-again stars would be of great importance to understand their composition and chemical evolution. In addition, the molecular emissio…

We present new ALMA Band 7 ( GHz) observations of the dense gas tracers HCN, HCO, and CS in the local, single-nucleus, ultraluminous infrared galaxy IRAS 13120-5453. W…
Decay mechanism and lifetime of Kr
L. V. Grigorenko, T. A. Golubkova, J. S. Vaagen +1
The lifetime of the recently discovered emitter Kr was recently found considerably below the lower limit predicted theoretically. This communication addresses this issu…
ALMA Observations of the Water Fountain Pre-Planetary Nebula IRAS 16342-3814: High-velocity bipolar jets and an Expanding Torus
R. Sahai, W. H. T. Vlemmings, T. Gledhill +4
We have mapped 12CO J=3-2 and other molecular lines from the "water-fountain" bipolar pre-planetary nebula (PPN) IRAS 16342-3814 with ~0."35 resolution using ALMA. We find (i) two…
Edge Momentum Transport by Neutrals: an Interpretive Numerical Framework
J. T. Omotani, S. L. Newton, I. Pusztai +3
Due to their high cross-field mobility, neutrals can contribute to momentum transport even at the low relative densities found inside the separatrix and they can generate intrinsic…
H12CN and H13CN excitation analysis in the circumstellar outflow of R Scl
M. Saberi, M. Maercker, E. De Beck +3
Abridged. The 12CO/13CO ratio in the circumstellar envelope (CSE) of asymptotic giant branch (AGB) stars has been extensively used as the tracer of the photospheric 12C/13C ratio.…
Edge rotation from momentum transport by neutrals
JT Omotani, SL Newton, I Pusztai +1
Due to their high cross field mobility, neutral atoms can have a strong effect on transport even at the low relative densities found inside the separatrix. We use a charge-exchange…
Strong coupling between an electron in a quantum dot circuit and a photon in a cavity
L. E Bruhat, T. Cubaynes, J. J. Viennot +4
Circuit quantum electrodynamics allows one to probe, manipulate and couple superconducting quantum bits using cavity photons at an exquisite level. One of its cornerstones is the p…
Resolved images of a protostellar outflow launched by an extended disk wind
Per Bjerkeli, Matthijs H. D. van der Wiel, Daniel Harsono +2
Young stars are associated with prominent outflows of molecular gas. The ejection of gas via these outflows is believed to remove angular momentum from the protostellar system, thu…
Observation of photon noise by cold-electron bolometers
A. V. Gordeeva, V. O. Zbrozhek, A. L. Pankratov +4
We have measured a response to a black body radiation and noise of the cold-electron bolometers. The experimental results have been fitted by theoretical model with two heat-balanc…

Sofia Wallstrom, E. Lagadec, S. Muller +12
Yellow hypergiants are rare and represent a fast evolutionary stage of massive evolved stars. That evolutionary phase is characterised by a very intense mass loss, the understandin…
