Self-diffusion in liquid gallium and hard sphere model
EPJ Web of Conferences, 2015 Incoherent and coherent components of quasielastic neutron scattering have been studied in the temperature range of T = 313 K – 793 K aiming to explore the applicability limits of the hard-sphere approach for the microscopic dynamics of liquid gallium ...

Molecular orientational melting within a lead-halide octahedra framework - the order-disorder transition in CH3NH3PbBr3 [PDF]
Phys. Rev. B 96, 174111 (2017), 2017 Lead-halide organic-inorganic perovskites consist of an inorganic host framework with an organic molecule occupying the interstitial space. The structure and dynamics of these materials have been heavily studied recently due to interest in their exceptional photovoltaic properties.

Spin dynamics of strongly-doped La_{1-x}Sr_xMnO_3
, 1997 Cold neutron triple-axis measurements have been used to investigate the nature of the long-wavelength spin dynamics in strongly-doped La$_{1-x}$Sr$_{x}$MnO$_3$ single crystals with $x$=0.2 and 0.3. Both systems behave like isotropic ferromagnets at low T,

Magnetic Bragg peak enhancement under ultrasound injection
Physical Review Research, 2022 Ultrasound injection effect on a magnetic Bragg peak of yttrium iron garnet has been studied by quasielastic neutron scattering. The magnetic Bragg peak is vastly enhanced with decreasing temperature.

Global superscaling analysis of quasielastic electron scattering with relativistic effective mass [PDF]
Phys. Rev. C 98, 024627 (2018), 2018 We present a global analysis of the inclusive quasielastic electron scattering data with a superscaling approach with relativistic effective mass. The SuSAM* model exploits the approximation of factorization of the scaling function $f^*(\psi^*)$ out of the cross section under quasifree conditions.

Yb-Yb correlations and crystal-field effects in the Kondo insulator YbB12 and its solid solutions
, 2004 We have studied the effect of Lu substitution on the spin dynamics of the Kondo insulator YbB12 to clarify the origin of the spin-gap response previously observed at low temperature in this material.

Scattering fingerprints of two-state dynamics
New Journal of Physics, 2022 Particle transport in complex environments such as the interior of living cells is often (transiently) non-Fickian or anomalous, that is, it deviates from the laws of Brownian motion.

Nuclear halo structure from quasielastic charge-exchange reactions [PDF]
Nucl.Phys. A755 (2005) 527-530, 2005 Neutron and proton densities in the nuclear periphery are investigated within (p,n) charge-exchange isobar transitions. For this purpose we have developed parameter-free optical potentials with a detailed treatment of the in-medium $t_{\tau}$ part of the effective interaction. Non local coupled-channel Lane equations are solved to obtain the scattering
