Quantum mechanical calculations of atomic systems comprise a suite of computational methods that rigorously apply the principles of quantum mechanics to determine a range of atomic properties. These ...

Quasicrystals couldn't be simulated with quantum mechanics because of their irregular atomic patterns. A new method overcomes this challenge. (Nanowerk News) A rare and bewildering intermediate ...

Classical computations rely on binary bits, which can be in either of the two states, 0 or 1. In contrast, quantum computing is based on qubits, which can be 0, 1, or a superposition or entanglement ...

NMAH copy purchased with funds from the S. Dillon Ripley Endowment. This comprehensive scientific history presents for the first time a detailed and comprehensive study of the Bohr atom in all its ...

A rare and bewildering intermediate between crystal and glass can be the most stable arrangement for some combinations of atoms, according to a study from the University of Michigan. The findings come ...
