Emergence of Spacetime from Fluctuations
Marcus Reitz, Barbara Šoda, Achim Kempf
We use a result of Hawking and Gilkey to define a Euclidean path integral of gravity and matter which has the special property of being independent of the choice of basis in the sp…
Exact Diagonalization of Sums of Hamiltonians and Products of Unitaries
Barbara Šoda, Achim Kempf
We present broadly applicable tools for determining the behavior of eigenvalues and eigenvectors under the addition of self-adjoint operators and under the multiplication of unitar…
Transmission of coherent information at the onset of interactions
Emily Kendall, Barbara Šoda, Achim Kempf
In this work, we investigate the parameters governing the rate at which a quantum channel arises at the onset of an interaction between two systems, and . In particular, whe…
Acceleration-induced effects in stimulated light-matter interactions
Barbara Šoda, Vivishek Sudhir, Achim Kempf
The interaction between light and an atom proceeds via three paradigmatic mechanisms: spontaneous emission, stimulated emission, and absorption. All three are resonant processes in…
