Fermionic condensation in ultracold atoms, nuclear matter and neutron stars [PDF]
J. Phys. Conf. Ser. 497, 012026 (2014), 2013 We investigate the Bose-Einstein condensation of fermionic pairs in three different superfluid systems: ultracold and dilute atomic gases, bulk neutron matter, and neutron stars.

Constraints on a possible dineutron state from pionless EFT [PDF]
, 2014 We investigate the sensitivity of the three-nucleon system to changes in the neutron-neutron scattering length to next-to-leading order in the pionless effective field theory, focusing on the the triton-3He binding energy difference and neutron-deuteron ...

Determining the relaxation time from a temperature-dependent scan of the neutron spin-echo signal amplitude [PDF]
EPJ Web of Conferences, 2022 Temperature-dependent scans of the neutron scattering intensity are commonly employed in high energy-resolution quasielastic measurements. Besides serving as a useful diagnostic tool for identifying the temperature range that could give rise to a ...

The high-Q static scattering of 3-methyl pyridine/D2O mixtures without and with antagonistic salt [PDF]
EPJ Web of Conferences, 2023 Here we focus on the high-Q small-angle neutron scattering where we observed deviations from an ideal power law Q−2. From theory, this deviation Δ arises from the critical correlation-function exponent ηd in d dimensions.
