Supercurrents and Tunneling in Massive Many‐Vortex Necklaces and Star‐Lattices

open access: yesAnnalen der Physik, EarlyView.
It is numerically shown how massive many‐vortex systems, in a mixture of Bose–Einstein condensates, can host the bosonic tunneling of the infilling component in an almost‐periodic way when the vortices are organized in necklaces or star‐lattices. The purpose is to explore the conditions for the onset of Josephson supercurrents in rotating many‐vortex ...

Inverting Palladium–Phosphorus Lewis Pair Formation: Phosphonium Acting as Z‐Type Ligand

open access: yesAngewandte Chemie International Edition, EarlyView.
A series of cationic phosphonium‐palladium(0) complexes were synthesized using an ambiphilic phosphorus‐based ligand. A strong Z‐type interaction was identified by DFT calculations (NBO, ETS‐NOCV, and QTAIM analyses), surpassing the strength of classical L‐type P─Pd bonds.

Two‐Time Approach to Past–Future Quantum Dynamics: Formalism and Applications

open access: yesAdvanced Physics Research, EarlyView.
A two‐time extension of the past‐future quantum state formalism is presented, describing systems with forward‐ and backward‐evolving states at distinct times. Using this framework, two‐time weak values are defined and applied them to Berry phase, spontaneous decay, and dwell time.

Theoretical Study on the Dynamical Stability, Chemical Bonding, and Electronic Properties of LaBH8 and LaBeH8 Under Pressure

open access: yesAdvanced Physics Research, EarlyView.
This work investigates the dynamic stability, chemical bonding and electronic properties of LaBH8 and LaBeH8 under pressure using first‐principles calculations. The authors reveal that LaBH8 contains strong covalent B–H bonds, while the Be–H bonds in LaBeH8 show ionic and covalent character. This study reveals the key chemical bonding character for the
