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…
On the size of superconducting islands on the density-wave background in organic metals
Vladislav D. Kochev, Seidali S. Seidov, Pavel D. Grigoriev
Most high- superconductors are spatially inhomogeneous. Usually, this heterogeneity originates from the interplay of various types of electronic ordering. It affects various s…
First-order phase transition between superconductivity and charge/spin-density wave as the reason of their coexistence in organic metals
Seidali S. Seidov, Vladislav D. Kochev, Pavel D. Grigoriev
The interplay between superconductivity (SC) and spin/charge density wave (DW) in organic metals shows many similarities to high- superconductors. It also contains many puzzle…
Improving of ultracold neutron traps coated with liquid helium using capillarity and electric field
Pavel D. Grigoriev, Arseniy V. Sadovnikov, Vladislav D. Kochev +1
To increase the storage time of ultracold neutrons (UCN) inside the material traps it is promising to cover the trap walls by liquid 4He, the material which does not absorb neutron…
Inhomogeneous superconductivity onset in FeSe studied by transport properties
P. D. Grigoriev, V. D. Kochev, A. P. Orlov +2
Heterogeneous superconductivity onset is a common phenomenon in high- superconductors of both the cuprate and iron-based families. It is manifested by a fairly wide transition…
Evolution of shape and volume fraction of superconducting domains with temperature and anion disorder in (TMTSF)ClO
Kaushal K. Kesharpu, Vladislav D. Kochev, Pavel D. Grigoriev
In highly anisotropic organic superconductor (TMTSF)ClO, superconducting (SC) phase coexists with metallic and spin density wave phases in the form of domains. Using the Ma…
Anisotropic zero-resistance onset in organic superconductors
Vladislav D. Kochev, Kaushal K. Kesharpu, Pavel D. Grigoriev
We study the coexistence of superconductivity (SC) and density-wave state and reconcile various puzzling experimental data in organic superconductors (TMTSF)PF and (TMT…
