Magnetic ordering in the ultra-pure site-diluted spin chain materials SrCuNiO
G. Simutis, M. Thede, R. Saint-Martin +8
Muon spin rotation technique is used to study magnetic ordering in ultra-pure samples of SrCuNiO, an archetypical antiferromagnetic Heisenberg chain system…
Towards a guided atom interferometer based on a superconducting atom chip
T. Mueller, X. Wu, A. Mohan +3
We evaluate the realization of a novel geometry of a guided atom interferometer based on a high temperature superconducting microstructure. The interferometer type structure is obt…
Spin pseudogap in Ni-doped SrCuO2
G. Simutis, S. Gvasaliya, M. Mansson +11
The S=1/2 spin chain material SrCuO2 doped with 1% S=1 Ni-impurities is studied by inelastic neutron scattering. At low temperatures, the spectrum shows a pseudogap Î~ 8 meV, abse…
On Thermal-Pulse-Driven Plasma Flows in Coronal Funnels as Observed by Hinode/EUV Imaging Spectrometer (EIS)
A. K. Srivastava, P. Konkol, K. Murawski +2
Using one-arcsecond-slit scan observations from the Hinode/EUV Imaging Spectrometer (EIS) on 05 February 2007, we find the plasma outflows in the open and expanding coronal funnels…
Bond disorder and spinon heat transport in the Heisenberg spin chain compound SrCuO: from clean to dirty limits
A. Mohan, N. Sekhar Beesetty, N. Hlubek +4
We investigate the effect of disorder on the heat transport properties of the Heisenberg chain compound SrCuO upon chemically substituting Sr by increasing…
Searching for star-planet interactions in GJ 486 at radio wavelengths with the uGMRT
L. Peña-Moñino, M. Pérez-Torres, D. Kansabanik +14
We search for radio emission from star-planet interactions in the M-dwarf system GJ~486, which hosts an Earth-like planet. We observed the GJ~486 system with the upgraded Giant Met…
Density dependence of the Ionization Avalanche in ultracold Rydberg gases
M. Siercke, F. E. Oon, A. Mohan +3
We report on the behaviour of the ionization avalanche in an ensemble of ultracold 87Rb atoms coupled to a high lying Rydberg state and investigate extensions to the current model…
