Heisenberg Model Ground State
Heisenberg Model Ground State. We find the exact ground state energy and magnetic moment for an arbitrary magnetic field h of the classical heisenberg model of spins on the vertices of an. (51), which we use to extract the.
The heisenberg model plays a central role in understanding quantum materials, realizing numerous quantum phases as ground states. Here we report the first experimental study using the geometric phase as a topological test of quantum transitions of the ground state in a heisenberg xy spin.
