A recent paper in the Journal of Computational Chemistry introduces a new framework for describing and analyzing turnstile-like ligand motions and other polytopal rearrangements in molecular systems.
To accompany the publication, the authors have released:
๐งฉ PyMOL plugin for visualizing generalized turnstile rotations
https://github.com/smutao/gTA-plugin
โ๏ธ Workflow scripts (xTB/ORCA interface) for relaxed scans and transition-state searches
https://github.com/smutao/gTA-workflow
The approach has been demonstrated on several representative systems, including SFโ, IFโ, [Co(en)โ]ยณโบ, and selected Bi/Ni complexes.

| 6 | Elk version 11.0.2 released
elk-11.0.2
-further improved the Wannier90 interface; individual angular momentum
values can be specified for each species (rather than just the maximum)
-updated the Wannier90 examples; thanks to Markus Meinert, Wenhan Chen,
LN and Sebastian Kalhoefer for all the testing
-Wannier90 parameter generation now parallelised with OpenMP; thanks to
Wenhan Chen
-added complicated magnetic FeGe Wannier90 example
-Sebastian Kalhoefer and LN added tesseral tensor moments
-removed the logical variables 'tm3vdl'
-added 'tm3type'; this is 0 for real tensor moments corresponding to
Hermitian Gamma matrices, 1 for complex van der Laan tensor moments and
2 for real tesseral tensor moments
-improved the GGA potential used in the atomic code; this results in a
better starting density when 'xctsp' is set to a GGA functional
-changed the ULR density calculation back to double-precision
-fixed a problem with the TD 'step' vector potential
-Inho Lee fixed an issue with the documentation for 'genafieldt'
-fixed an issue which sometimes made CPU timings negative
-several improvements and optimisations
-added more documentation

Chemical bonding concepts emerge naturally from maximally entangled atomic orbitals
Maximally entangled atomic orbitals provide a quantitative orbital-entanglement route to identify Lewis, multicenter, and aromatic bonding patterns beyond conventional localized-orbital pictures.

| 13 | Fun fact of the day
In nonadiabatic dynamics, the sign of an electronic eigenvector is arbitrary. A wavefunction can flip phase between adjacent MD steps without changing any observable, but finite-difference nonadiabatic couplings will treat that sign flip as a huge artificial derivative unless the phases are corrected. That is why the new CP2K NAC framework explicitly includes phase correction. | 1 416 |
