Neutrino spin oscillations near a black hole

Mridupawan Deka, Maxim Dvornikov In this work, we study neutrino spin oscillations in the case when they are gravitationally scattered off a rotating Kerr black hole surrounded by a thick magnetized accretion disk. We consider only toroidal magnetic field inside the disk. Neutrino spin precession is caused by the interaction of …

Spin Oscillations in Neutrino Gravitational Scattering

Mridupawan Deka and Maxim Dvornikov We study neutrino spin oscillations while the particles scatter off a rotating black hole surrounded by a thick magnetized accretion disk. Neutrino spin precession is caused by the interaction of the neutrino magnetic moment with the magnetic field in the disk which has both toroidal …

Skyrmion crystal phase on a magnetic domain wall in chiral magnets

Yuki Amari, Muneto Nitta We study a magnetic domain wall in the ferromagnetic phase in chiral magnets in two dimensions with an in-plane easy-axis anisotropy and an out-of-plane Zeeman magnetic field, and find a chiral soliton lattice (spiral) phase beside a ferromegnetic phase inside the domain line, where the former represents …

Domain-wall skyrmion chain and domain-wall bimerons in chiral magnets

Yuki Amari, Calum Ross, and Muneto Nitta We construct domain-wall skyrmion chains and domain-wall bimerons in chiral magnets with an out-of-plane easy-axis anisotropy and without a Zeeman term coupling to a magnetic field. Domain-wall skyrmions are skyrmions trapped inside a domain wall, and they are present in the ferromagnetic (FM) phase of …

Searching for New Nontrivial Choreographies for the Planar Three-Body Problem

Hristov, I., Hristova, R., Puzynin, I., Puzynina, T., Sharipov, Z., Tukhliev, Z. A specialized numerical search for new nontrivial choreographies for the planar three-body problem is made. With only three known so far nontrivial choreographies, we found 161 new ones. The linear stability of all found orbits is investigated by …

Theoretical predictions of properties and adsorption behaviour of a superheavy element Ts and its lighter homolog At, and of their various gas-phase compounds, on hydroxylated quartz surfaces from periodic DFT calculations

Miroslav Iliaš, Valeria Pershina Adsorption energies, Eads, of a superheavy element Ts and its lighter homolog At, as well as of their various oxides, hydrides, and (oxy)hydroxides on hydroxylated quartz surfaces are calculated using a periodic density functional theory implemented in the AMS BAND software. It was shown that elemental At …

Generating and grading 34 optimised norm-conserving Vanderbilt pseudopotentials for actinides and super-heavy elements in the PseudoDojo

Christian Tantardini, Miroslav Iliaš, Matteo Giantomassi, Alexander G. Kvashnin, Valeria Pershina, Xavier Gonze In the last decades, material discovery has been a very active research field driven by the need to find new materials for many different applications. This has also included materials with heavy elements, beyond the stable isotopes of lead, …

Impact of mutations on the stability of SARS-CoV-2 nucleocapsid protein structure

Nelli Muradyan, Vahram Arakelov, Arsen Sargsyan, Adrine Paronyan, Grigor Arakelov, Karen Nazaryan The nucleocapsid (N) protein of SARS-CoV-2 is known to participate in various host cellular processes, including interferon inhibition, RNA interference, apoptosis, and regulation of virus life cycles. Additionally, it has potential as a diagnostic antigen and/or immunogen. Our research focuses on examining structural …

In Silico Study of Pyrin and 14-3-3 Protein Modulation During FMF and PAAND

Adrine Paronyan, Nelli Muradyan, Arsen Sargsyan, Vahram Arakelov, Grigor Arakelov, Karen Nazaryan Familial Mediterranean fever (FMF) is a genetically determined disease transmitted through autosomal recessive inheritance. Recently, a rare but similar disease to FMF, pyrin-associated autoinflammation with neutrophilic dermatosis (PAAND), has been discovered. PAAND is inherited dominantly and is characterized by neutrophilic dermatosis and recurrent …
