The generalized Lindemann melting coefficient [PDF]
, 2020 Lindemann developed the melting temperature theory over 100 years ago, known as the Lindemann criterion. Its main assumption is that melting occurs when the root-mean-square vibration amplitude of ions and atoms in crystals exceeds a critical fraction, h

From the Mendeleev periodic table to particle physics and back to the periodic table [PDF]
, 2006 We briefly describe in this paper the passage from Mendeleev's chemistry (1869) to atomic physics (in the 1900's), nuclear physics (in the 1932's) and particle physics (from 1953 to 2006).

Particular Symmetries: Group Theory of the Periodic System
Substantia, 2020 To this day, a hundred and fifty years after Mendeleev's discovery, the overal structure of the periodic system remains unaccounted for in quantum-mechanical terms.

The Mendeleev-Meyer force project [PDF]
, 2016 Here we present the Mendeleev–Meyer Force Project which aims at tabulating all materials and substances in a fashion similar to the periodic table. The goal is to group and tabulate substances using nanoscale force footprints rather than atomic number or

Zeeman slowing of a group-III atom
Physical Review Research, 2022 We realize a Zeeman slower of an atom in main group III of the Periodic Table, otherwise known as the “triel elements.” Despite the fact that our atom of choice (namely indium) does not have a ground state cycling transition suitable for laser cooling ...

Energy of Substitution of Anions and Cations in Zinc and Cadmium Telluride
Фізика і хімія твердого тіла, 2017 Energy substitution of cations and anions in ZnTe i CdTe by atoms from first and seventh group of the periodic table were calculated using the method of bonding orbitals. Based on the results conclusions about the most likely types of defects by doping.

Alchemical and structural distribution based representation for improved QML
, 2017 We introduce a representation of any atom in any chemical environment for the generation of efficient quantum machine learning (QML) models of common electronic ground-state properties.
