Lorenz Gauge in Quantum Cosmology
Giampiero Esposito, Giuseppe Pollifrone
In a path-integral approach to quantum cosmology, the Lorenz gauge-averaging term is studied for Euclidean Maxwell theory on a portion of flat four-space bounded by two concentric…

Boundary Terms for Massless Fermionic Fields
Giampiero Esposito, Hugo A. Morales-Tecotl, Giuseppe Pollifrone
Local supersymmetry leads to boundary conditions for fermionic fields in one-loop quantum cosmology involving the Euclidean normal to the boundary and a pair of independent spinor…

Twistors and Spin 3/2 Potentials in Quantum Gravity
Giampiero Esposito, Giuseppe Pollifrone
Local boundary conditions involving field strengths and the normal to the boundary, originally studied in anti-de Sitter space-time, have been recently considered in one-loop quant…
