Photon self-interaction through gravitons and axions
Ahmad Hoseinpour, Moslem Zarei, Mehdi Abdi
In this work, we propose to employ the concept of photon self-interaction for axion detection. In particular, we derive the interaction Hamiltonian for photons via axions in a ring…
Quantum Boltzmann equation for fermions: An attempt to calculate the NMR relaxation and decoherence times using quantum field theory techniques
Hassan Manshouri, Ahmad Hoseinpour, Moslem Zarei
Extracting macroscopic properties of a system from microscopic interactions has always been an interesting topic with the most diverse applications. Here, we use the quantum Boltzm…
CMB modes from photon-photon forward scattering revisited
Ahmad Hoseinpour, Moslem Zarei, Giorgio Orlando +2
Recent literature has shown that photon-photon forward scattering mediated by Euler-Heisenberg interactions may generate some amount of the circular polarization ( modes) in the…
CMB circular and B-mode polarization from new interactions
Nicola Bartolo, Ahmad Hoseinpour, Sabino Matarrese +2
Standard models describing the radiation transfer of the cosmic microwave background (CMB) through Compton scattering predict that cosmological scalar perturbations at linear order…
Photon-graviton scattering: A new way to detect anisotropic gravitational waves?
Nicola Bartolo, Ahmad Hoseinpour, Giorgio Orlando +2
Gravitons are the quantum counterparts of gravitational waves in low-energy theories of gravity. Using Feynman rules one can compute scattering amplitudes describing the interactio…
