A discrete series gauge field at the late-time boundary of
Manizheh Botshekananfard, Elif Büşra Güraksın, Vasileios A. Letsios +1
We study the free Maxwell field on the planar patch of four-dimensional de Sitter spacetime (). We review its bulk canonical quantization in the Bunch-Davies vacuum, and we g…
Generalized Fock--Lorentz Transformations from Projective Conformal Coordinates: Covariant Structure, Sector Classification, and Oscillator Limits
Abdelmalek Boumali, N. Jafari, M. Botshekananfard
We develop a covariant projective formulation of generalized Fock--Lorentz (GFL) transformations based on the auxiliary Minkowski coordinates , where is a…
Klein-Gordon and Dirac Oscillators in a Constant-Curvature Fock-Lorentz Background
Abdelmalek Boumali, N. Jafari, Manizheh Botshekananfard
We propose a controlled momentum-space dual of the Fock--Lorentz (FL) transformations and use it to derive a deformed relativistic mass shell. Restricting the FL conformal factor t…
Induced energy-momentum tensor of the scalar field in 3D de Sitter QED
Manizheh Botshekananfard, Takahiro Hayashinaka
In this work, we derive the renormalized expectation value of the energy--momentum tensor of a quantized charged scalar field in three-dimensional de Sitter spacetime $\mathrm{dS}_…
Ladder operators of the de Sitter algebra
Manizheh Botshekananfard, Elif Büşra Güraksın, Gizem Şengör
We identify raising and lowering operators of the de Sitter algebra with focus on their action on states in particular in 4 spacetime dimensions. There isn't a unique solution to t…
Two-dimensional electron gas under the effect of constrained potential and magnetic field in curved space
H. Pahlavani, M. Botshekananfard
The effect of the curvature of a cylindrical surface on the energy spectrum for a curved two-dimensional electron gas in a homogeneous magnetic field is considered. The corrections…
Induced energy-momentum tensor of Dirac field in 2D de Sitter QED
Manizheh Botshekananfard, Ehsan Bavarsad
We compute the expectation value of the energy-momentum tensor in the in-vacuum state of the quantized Dirac field coupled to a uniform electric field background on the Poincar$\rm…
