Weak Coupling Limit of U(1) Lattice Model in Fourier Basis
Afsaneh Kianfar, Amir H. Fatollahi
The transfer-matrix of the U(1) lattice model is considered in the Fourier basis and in the weak coupling limit. The issues of Gauss law constraint and gauge invariant states are a…
Diagrammatic Strong Coupling Expansion of U(1) Lattice Model in Fourier Basis
Afsaneh Kianfar, Amir H. Fatollahi
The transfer-matrix of U(1) lattice gauge theory is investigated in the field Fourier space, the basis of which consists of the quantized currents on lattice links. Based on a latt…
On U(1) Gauge Theory Transfer-Matrix in Fourier Basis
Narges Vadood, Amir H. Fatollahi
The properties of the transfer-matrix of U(1) lattice gauge theory in the Fourier basis are explored. Among other statements it is shown: 1) the transfer-matrix is block-diagonal,…
Lost in Normalization
Narges Vadood, Amir H. Fatollahi
The consequences of the gauge-coupling dependent normalization-factor of in the transfer-matrix of 2d U(1) lattice gauge theory are explored. It is seen by the choice…
