New nuclear-electronic orbital (NEO) features: NEO-SCS-RIMP2 and NEO-SOS'-OOMP2! These methods provide improved accuracy over NEO-MP2 by compensating for the lack of orbital optimization, yielding results that are competitive with NEO-CCSD methods while retaining MP2's favorable scaling. NEO methods account for nuclear motion in quantum chemistry simulations, allowing key nuclear quantum effects to be incorporated! Check out the publication linked below, in which the developers use it to model anharmonic zero-point energies and relative energies in protonated water clusters.

Witness the extraordinary Cherenkov effect in nuclear reactors, where electrons seemingly travel faster than light. This phenomenon occurs when a charged particle, like an electron, moves through a transparent medium such as water or air at speeds greater than the phase velocity of light in that medium. The result? A striking blue glow. The Cherenkov effect not only dazzles but also aids in detecting high-energy particles and radiation, showcasing the captivating interplay between physics and nuclear technology. #Physics #NuclearTech #ScienceMagic

Plasma regimes without large edge localized modes (#ELMs)? Here's an update about 3D non-linear simulations using the #JOREK code by Andres Cathey, just accepted for publication in the journal Nuclear Fusion. This is a proceedings article for his oral contribution to the IAEA Fusion Energy Conference last year. The article summarizes progress on simulating Quiescent H-mode, the Quasi-Continuous Exhaust regime, the enhanced D-alpha H-mode and deals with experiment validation in the ASDEX Upgrade device operated at Max-Planck-Institut für Plasmaphysik - IPP as well as first predictive studies for the JT60-SA tokamak in Japan.

"Heisenberg Parabolic Subgroup of SO∗(10) and Invariant Differential Operators" 🔸https://lnkd.in/ezrmcTDE 🔹Author: Vladimir Dobrev Institute for Nuclear Research and Nuclear Energy, Bulgarian Academy of Sciences 🔸Abstract: In the present paper we continue the project of systematic construction of invariant differential operators on the example of the non-compact algebra 𝑠𝑜∗(10). We use the maximal Heisenberg parabolic subalgebra 𝒫=ℳ⊕𝒜⊕𝒩 with ℳ=𝑠𝑢(3,1)⊕𝑠𝑢(2)≅𝑠𝑜∗(6)⊕𝑠𝑜(3). We give the main and the reduced multiplets of indecomposable elementary representations. This includes the explicit parametrization of the intertwining differential operators between the ERS... #subgroup #invariant #differential #operators  Physics Section of Symmetry
