The concept of phase space amplitudes for systems with continuous degrees of freedom is generalized to finite-dimensional spin systems. Complex amplitudes are obtained on both a sphere and a finite la...
Many-body spin interactions and the ground state of a dense Rydberg lattice gas
Many-body spin interactions ground state dense Rydberg lattice gas
