Oscillators with imaginary coupling: spectral functions in quantum mechanics and quantum field theory
Bruno W. Mintz, Itai Y. Pinheiro, Rui Aquino
The axioms of Quantum Mechanics require that the hamiltonian of any closed system is self-adjoint, so that energy levels are real and time evolution preserves probability. On the o…

Scalar field theory under Robin boundary conditions: two-point function and energy-momentum tensor
David Dudal, Aaron Gobeyn, Bruno W. Mintz +2
We reconsider four-dimensional scalar field theory in presence of Robin boundary conditions on two parallel plates. These boundary conditions are directly imposed in the path integ…
