Monte Carlo study on Heisenberg model with local dipolar interaction
Etsuko Itou, Akira Matsumoto, Yu Nakayama +1
Aharony and Fisher showed that non-local dipolar effects in magnetism destabilize the Heisenberg fixed point in real ferromagnets, leading to a new fixed point, called the dipolar…

Computing theta-dependent mass spectrum of the 2-flavor Schwinger model in the Hamiltonian formalism
Akira Matsumoto, Etsuko Itou, Yuya Tanizaki
We compute the -dependent mass spectrum of the 2-flavor Schwingr model using the tensor network (DMRG) in the Hamiltonian formalism. The pion and the sigma meson are identified…
