A selection rule for transitions in PT-symmetric quantum theory
Lawrence R. Mead, David Garfinkle
Carl Bender and collaborators have developed a quantum theory governed by Hamiltonians that are PT-symmetric rather than Hermitian. To implement this theory, the inner product was…
On Field Theory Thermalization from Gravitational Collapse
David Garfinkle, Leopoldo A. Pando Zayas, Dori Reichmann
Motivated by its field theory interpretation, we study gravitational collapse of a minimally coupled massless scalar field in Einstein gravity with a negative cosmological constant…
Rapid Thermalization in Field Theory from Gravitational Collapse
David Garfinkle, Leopoldo A. Pando Zayas
Motivated by the duality with thermalization in field theory, we study gravitational collapse of a minimally coupled massless scalar field in Einstein gravity with a negative cosmo…
Non-Stationary Dark Energy Around a Black Hole
Ratindranath Akhoury, David Garfinkle, Ryo Saotome +1
Numerical simulations of the accretion of test scalar fields with non-standard kinetic terms (of the k-essence type) onto a Schwarzschild black hole are performed. We find a full d…
Evolution to a smooth universe in an ekpyrotic contracting phase with w > 1
David Garfinkle, Woei Chet Lim, Frans Pretorius +1
A period of slow contraction with equation of state w > 1, known as an ekpyrotic phase, has been shown to flatten and smooth the universe if it begins the phase with small perturba…
