Gravitational Background of Alice-Vortices and R7-Branes
Atakan Çavuşoğlu, Mirjam Cvetič, Jonathan J. Heckman +2
Codimension-two vortex solutions are important solitonic objects in both quantum field theory and gravity. In this paper, we construct a class of codimension-two Alice-vortex solut…

Primordial Gravitational Waves in Quadratic Gravity
Jisuke Kubo, Jeffrey Kuntz
Quadratic gravity is a fourth-order (in derivatives) theory that can serve as an attractive upgrade to the standard description of gravity provided by General Relativity, thanks to…

Unitarity through PT symmetry in Quantum Quadratic Gravity
Jeffrey Kuntz
Theories described by non-Hermitian Hamiltonians are known to possess strictly positive energy eigenvalues and exhibit unitary time evolution if the Hamiltonian is symmetric under…
