Towards a transferable fermionic neural wavefunction for molecules
In the following, we briefly outline our approach and how it extends existing work (A multi-compound wavefunction ansatz). We show the fundamental properties of our ansatz such as extensivity and equivariance with respect to the sign of reference orbitals. We demonstrate the transferability of the ansatz when pre-training on small molecules and re-using it on…

Thermal and optical properties of P3HT:PC70BM:ZnO nanoparticles composite films
X-Ray diffraction In order to examine the presence of ZnO-NPs in composite films, impact of thermal annealing and to determine the effect of the polymer molecular weight on the microstructure of composite films, we conducted detailed X-ray diffraction studies, which included powders of purchased materials and films obtained from their mixtures with an increasing number…

Field-induced compensation of magnetic exchange as the possible origin of reentrant superconductivity in UTe2
We investigated several micron-sized samples produced from one oriented single crystal with a superconducting Tc of 1.6 K. The micromachining was performed by means of Ga or Xe FIB systems (for details, see the methods section). This FIB approach enables precise geometries suitable for microcantilever-torque experiments on magnetic materials with strong torque responses as well as…

Colloidal pathways of amorphous calcium carbonate formation lead to distinct water environments and conductivity
Materials All solutions were prepared using Milli-Q water that was degassed by bubbling N2 through the solution overnight to remove dissolved CO2. 20 mM CaCl2 and 20 mM NaOH solutions were prepared by dilution of CaCl2 stock solution (1.0 M, VWR, AVS Titrinorm volumetric solution) and NaOH stock solution (0.1 N, Carl Roth), respectively. Carbonate buffer solutions were freshly…

Dynamical behavior of solitons of the (2+1)-dimensional Konopelchenko Dubrovsky system
The transformations \(u(x,y,t)=U(\zeta )\) and \(v(x,y,t)=V(\zeta )\), where \(\zeta =\alpha x+\beta y-\mu t\) in Eq. (1), lead to the NLODE system presented below. $$\begin{aligned}{}&\beta U^{\prime }(\zeta )=\alpha V^{\prime }(\zeta ) \\&\quad \frac{3}{2} a^2 \alpha U(\zeta )^2 U^{\prime }(\zeta )+3 a \alpha V(\zeta ) U^{\prime }(\zeta )-6 \alpha b U(\zeta ) U^{\prime }(\zeta )-\mu U^{\prime }(\zeta…

DFT study, and natural bond orbital (NBO) population analysis of 2-(2-Hydroxyphenyl)-1-azaazulene tautomers and their mercapto analouges
Geometry optimization Figure 2 lists the tautomeric structures of 2HPhAZ and 2MPhAZ (enolimines/thiol and ketoenamines/thione forms). Table 1 lists all the optimized structural properties determined in gas phase, and ethanol at the B3LYP/6–311 + + G(2d,2p) level of theory. Table 1 shows that the bond lengths in the tautomeric structure of 2HPhAZ (enolimines and ketoenamines form) are shorter than…
