We study the phase diagram in the (β,κ) plane performing a detailed analysis of the scaling behavior of the Lee-Yang zeros and the peak height of the chiral susceptibility. Our results strongly indicate that the whole range of the phase transition line starting from (β,κ)=(0.0,0.380665(59)) and ending at (∞,0.25) belongs to the two-dimensional Ising universality class similar to the free fermion case.}, title = {Grassmann tensor renormalization group approach to one-flavor lattice Schwinger model}, volume = {90}, year = {2014}, yomi = {クラマシ, ヨシノブ} }
