In the coming decades, the great American political debates will be less and less likely to feature Franklin Roosevelt-style Democrats squaring off against Ronald Reagan-style Republicans. Although ...

Researchers have developed an efficient way to characterize the effective many-body Hamiltonian of the solid-state spin system associated with a nitrogen-vacancy (NV) centre in diamond. The technique ...

Hermitian Hamiltonians are a fundamental concept in quantum mechanics, serving as the mathematical foundation for describing the energy and time evolution of quantum systems. They are named after the ...
