Thermodynamics of the one-dimensional SU(4) symmetric spin-orbital model
Beat Frischmuth, Frederic Mila, Matthias Troyer
The ground state properties and the thermodynamics of the one-dimensional SU(4) symmetric spin system with orbital degeneracy are investigated using the quantum Monte Carlo loop al…
