Quantum Field Theories of dense, cold matter

The density of states method applied to the Ising model with an imaginary magnetic field


  • Dr. Philippe DE FORCRAND

Primary authors



Above the Curie temperature, the Ising model partition function can vanish under the effect of an imaginary magnetic field, as first shown by Lee and Yang. This system has a severe sign problem. We study it numerically, using the density of states method. In particular, we consider how the computer effort scales with the system size.
