Five-point Type IIB String Amplitudes at One Loop
Emiel Claasen, Mehregan Doroudiani
Massless type IIB superstring amplitudes are organized according to the number of external states and their charge under the R-symmetry of type IIB supergravity. I…
From Modular Graph Forms to Iterated Integrals
Emiel Claasen, Mehregan Doroudiani
Modular graph forms are a class of non-holomorphic modular forms that arise in the low-energy expansion of genus-one closed string amplitudes. In this work, we introduce a systemat…
Type II superstring amplitude at one-loop and transcendentality
Emiel Claasen, Mehregan Doroudiani
We calculate the four-graviton scattering amplitude in Type II superstring theory at one loop up to seventh order in the low-energy expansion through the recently developed iterate…
Canonicalizing zeta generators: genus zero and genus one
Daniele Dorigoni, Mehregan Doroudiani, Joshua Drewitt +5
Zeta generators are derivations associated with odd Riemann zeta values that act freely on the Lie algebra of the fundamental group of Riemann surfaces with marked points. The genu…
Non-holomorphic modular forms from zeta generators
Daniele Dorigoni, Mehregan Doroudiani, Joshua Drewitt +5
We study non-holomorphic modular forms built from iterated integrals of holomorphic modular forms for SL known as equivariant iterated Eisenstein integrals. A specia…
Integral of depth zero to three basis of Modular Graph Functions
Mehregan Doroudiani
Modular Graph Functions (MGFs) are SL(2,)-invariant functions that emerge in the study of the low-energy expansion of the one-loop closed string amplitude. To find the…
Modular graph forms from equivariant iterated Eisenstein integrals
Daniele Dorigoni, Mehregan Doroudiani, Joshua Drewitt +5
The low-energy expansion of closed-string scattering amplitudes at genus one introduces infinite families of non-holomorphic modular forms called modular graph forms. Their differe…
Planar Maximally Entangled States
Mehregan Doroudiani, Vahid Karimipour
We construct a large family of Planar Maximally Entangled (PME) states which are a wider class of multi-partite entangled states than Absolutely Maximally Entangled (AME) states. T…
Complexity for Charged Thermofield Double States
Mehregan Doroudiani, Ali Naseh, Reza Pirmoradian
We study Nielsen's circuit complexity for a charged thermofield double state (cTFD) of free complex scalar quantum field theory in the presence of background electric field. We sho…
