Analyticity and positivity of Green's functions without Lorentz
Paolo Creminelli, Alessandro Longo, Borna Salehian +1
We study the properties imposed by microcausality and positivity on the retarded two-point Green's function in a theory with spontaneous breaking of Lorentz invariance. We assume i…
A Geometric View on Crossing-Symmetric Dispersion Relations
Joan Elias Miro, Andrea Guerrieri, Mehmet Asim Gumus +1
We introduce a general framework for constructing dispersion relations using crossing-symmetric variables, leading to infinitely many distinct representations of the 2-to-2 scatter…
Bootstrapping leading hadronic muon anomaly
Ahmadullah Zahed
We bootstrap the leading order hadronic contribution to using unitarity, analytic properties, crossing symmetry and finite energy sum rules (FESR) from quantum chromodynamic…
Complexity for one-dimensional discrete time quantum walk circuits
Aranya Bhattacharya, Himanshu Sahu, Ahmadullah Zahed +1
We compute the complexity for the mixed state density operator derived from a one-dimensional discrete-time quantum walk (DTQW). The complexity is computed using a two-qubit quantu…
