Relativistic frequency shifts in a rotating waveguide
M. Khorrami, A. H. Fatollahi, A. Shariati
A photon source is located in a rotating waveguide. An absorber with a sharp absorbing frequency absorbs some of the emitted photons. This decreases the number of photons which are…
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…
Identities for Droplets with Circular Footprint on Tilted Surfaces
Francois Dunlop, Amir H. Fatollahi, Maryam Hajirahimi +1
Exact mathematical identities are presented between the relevant parameters of droplets displaying circular contact boundary based on flat tilted surfaces. Two of the identities ar…
First-Order Phase Transition by XY Model of Particle Dynamics
Amir H. Fatollahi
A gas-liquid type of phase transition is found based on the particle dynamics on radius- circle in which the coordinate appears as the angle-variable of 1D XY-model. Due to the…
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,…
