Catalysis refers to the possibility of enabling otherwise inaccessible quantum state transitions by supplying an auxiliary system, provided that the auxiliary is returned to its initial state at the end of the protocol. We show that…

The behavior of fluids in the vicinity of the liquid-gas critical point is studied within the cell fluid model framework. The analytic method for deriving the equation of state of a cell fluid model in the low-temperature region (T<Tc) is…

The tetraaza [Co$^\text{II}$N$_4$H]$^{2+}$ complex (\textbf{1}) is remarkable for its ability to selectively reduce CO$_2$ to CO with 45\% Faradaic efficiency and a CO to H$_2$ ratio of 3:2. We employ density functional theory (DFT) to…

Femtoscopy measures space-time characteristics of the particle emitting source created in relativistic heavy-ion collisions. It is argued that collective behavior of matter (radial flow) produces specific femtoscopic signatures. The one…
