Spin operator matrix elements in the quantum Ising chain: fermion approach
Spin operator matrix elements quantum Ising chain
2010/12/27
Using some modification of the standard fermion technique we derive factorized formula for spin operator matrix elements (form-factors) between general eigenstates of the Hamiltonian of quantum Ising ...
