Entropy in the SU(N) Hubbard Model

Understanding entropy in the SU(N) Hubbard model is essential for interpreting recent ultracold atom experiments and for developing reliable thermometry in quantum simulators. We employ the diagrammatic Monte Carlo method with the combinatorial summation (CoS) algorithm ---which does not scale with the number of spin components, N--- to study the thermodynamics of this model with controlled precision over a wide range of parameters. Our results serve as accurate benchmarks for future theoretical and experimental investigations.
