DOI: 10.1103/physrevd.101.054507
Abstract: We numerically study the single-flavor Schwinger model with a topological $\theta$-term, which is practically inaccessible by standard lattice Monte Carlo simulations due to the sign problem. By using numerical methods based on tensor networks, especially… read more here.

DOI: 10.1103/physrevd.105.016028
Abstract: We investigate the massive Schwinger model in d = 1 + 1 dimensions using bosonization and the non-perturbative functional renormalization group. In agreement with previous studies we find that the phase transition, driven by a… read more here.

DOI: 10.1103/physrevd.99.094501
Abstract: We study the dynamics of the massive Schwinger model on a lattice using exact diagonalization. When periodic boundary conditions are imposed, analytic arguments indicate that a non-zero electric flux in the initial state can "unwind"… read more here.

DOI: 10.1103/physrevlett.125.181601
Abstract: I discuss the two-flavor Schwinger model both without and with fermion masses. I argue that the phenomenon of "conformal coalescence," in unparticle physics in which linear combinations of short-distance operators can disappear from the long-distance… read more here.

DOI: 10.1140/epjc/s10052-021-08987-z
Abstract: The $$(1+1)$$ dimensional generalized model where vector and axial vector interaction get mixed up with different strength is considered. Imposing a chiral constraint, the model can be expressed in terms of chiral boson. Then the… read more here.

DOI: 10.1142/s0217732322502522
Abstract: The light-front Schwinger model in the bosonized form is analyzed focusing on its global properties. We point out that the gauge invariance of the original fermionic form of the model is lost after bosonization. Consequently,… read more here.
