DOI: 10.1007/jhep08(2020)018
Abstract: In the first-quantised worldline approach to quantum field theory, a long-standing problem has been to extend this formalism to amplitudes involving open fermion lines while maintaining the efficiency of the well-tested closed-loop case. In the… read more here.

DOI: 10.1016/j.actaastro.2017.04.015
Abstract: Abstract Two-Line Elements (TLEs) continue to be the sole public source of orbiter observations. The accuracy of TLE propagations through the Simplified General Perturbations-4 (SGP4) software decreases dramatically as the propagation horizon increases, and thus… read more here.

Abstract: Using Laplace’s method, Green’s function of the operator ∂t−12∂x2+k2x−2+12ω2x2,k≥−14, ω≥0 is calculated in the half-space x > 0. Therefrom, we deduce the propagator of Schrodinger’s equation with the potential V(x) = kx−2 + ω2x2 for k≥34. read more here.

DOI: 10.1088/1361-6382/ab4dfd
Abstract: We advance a proposal of perturbative polymer field theory motivated by the study of the high energy regime of scalar propagator in flat spacetime. To do so we revisit the model by Hossain, Husain and… read more here.

DOI: 10.1088/1367-2630/abd43b
Abstract: Divisible dynamical maps play an important role in characterizing Markovianity on the level of quantum evolution. Divisible maps provide an important generalization of Markovian semigroups. Usually one analyzes either completely positive or just positive divisibility… read more here.

Abstract: The Feynman propagator G(x1,x2) encodes all of the physics contained in a free field and transforms as a covariant biscalar. Therefore, we should be able to discover the thermality of the Rindler horizon just by… read more here.
