Tuning Charge Density Wave transitions through lattice strain in NbSe3
Antoine Gallo Frantz, Aleksander Sinchenko, Luc Ortega +7
The Charge Density Wave (CDW) state is a perfect example of a combined structural and electronic state, both characterized by a periodic lattice distortion and an electronic modula…
A method for measuring deviation from Lambert diffuse scattering law of ultracold neutrons on material walls
P. D. Grigoriev, V. D. Kochev, V. A. Tsyplukhin +2
Modeling the motion of ultracold neutrons (UCNs) is crucial for assessing their losses, accurately measuring their lifetime, and describing other experiments. In material traps, it…
Numerical Calculation of Electric Field Enhancement in Neutron Traps with Rough Walls Coated with Superfluid Helium
V. D. Kochev, T. I. Mogilyuk, S. S. Kostenko +1
A film of liquid helium on the surface of material traps for ultracold neutrons protects the neutrons from being absorbed by the trap walls. By using surface roughness and an elect…
Loss rate of ultracold neutrons due to the absorption by trap walls in large material traps
Pavel D. Grigoriev, Vladislav D. Kochev, Victor A. Tsyplukhin +2
The most accurate neutron lifetime measurements now use the material or magnetic traps of ultracold neutrons (UCN). The precision of these experiments is determined by the accuracy…
3D-2D crossover and phase shift of beats of quantum oscillations of interlayer magnetoresistance in quasi-2D metals
Taras Mogilyuk, Pavel Grigoriev, Vladislav Kochev +2
Magnetic quantum oscillations (MQO) are traditionally applied to investigate the electronic structure of metals. In layered quasi-two-dimensional (Q2D) materials the MQO have sever…
