Multidimensional Worldline Instantons
Gerald V. Dunne, Qing-hai Wang
We extend the worldline instanton technique to compute the vacuum pair production rate for spatially inhomogeneous electric background fields, with the spatial inhomogeneity being…
Fluctuations about Cosmological Instantons
Gerald V. Dunne, Qing-hai Wang
We study the semiclassical fluctuation problem around bounce solutions for a self-interacting scalar field in curved space. As in flat space, the fluctuation problem separates into…
Worldline Instantons II: The Fluctuation Prefactor
Gerald V. Dunne, Holger Gies, Christian Schubert +1
In a previous paper [1], it was shown that the worldline expression for the nonperturbative imaginary part of the QED effective action can be approximated by the contribution of a…
Secondary pairing in gapless color-superconducting quark matter
Mark Alford, Qing-hai Wang
We calculate secondary pairing in a model of a color superconductor with a quadratic gapless dispersion relation for the quasiquarks of the primary pairing. Our model mimics the ph…
Photons in gapless color-flavor-locked quark matter
Mark Alford, Qinghai Wang
We calculate the Debye and Meissner masses of a gauge boson in a material consisting of two species of massless fermions that form a condensate of Cooper pairs. We perform the calc…
The C Operator in PT-Symmetric Quantum Field Theory Transforms as a Lorentz Scalar
Carl M. Bender, Sebastian F. Brandt, Jun-Hua Chen +1
A non-Hermitian Hamiltonian has a real positive spectrum and exhibits unitary time evolution if the Hamiltonian possesses an unbroken PT (space-time reflection) symmetry. The proof…
