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 ...

In Land of Promise, Michael Lind argues that America’s political economy has historically oscillated between two schools of thought: Hamiltonians, who believe in a strong federal government to ...

Earlier today I set you two puzzles based on Hamiltonian paths in a square grid. A Hamiltonian path is one which visits every cell exactly once. (If you want a print out of the puzzles, click here.) 1 ...

The natural Hamiltonian function in optimal control is generally not differentiable. However, it is possible to use the theory of generalized gradients (which we discuss as a preliminary) to obtain ...

A century ago, progressives were challenged to achieve “Jeffersonian ends by Hamiltonian means.” Beginning with Herbert Croly’s The Promise of American Life, and continuing through the New Deal, ...
