Testing Hamiltonian Reduced QED
Thomas C. Bachlechner
Certain gauge transformations may act non-trivially on physical states in quantum electrodynamics (QED). This observation has sparked the yet unresolved question of how to characte…
Testing the electric Aharonov-Bohm effect with superconductors
Thomas C. Bachlechner, Matthew Kleban
The phase of the wave function of charged matter is sensitive to the value of the electric potential, even when the matter never enters any region with non-vanishing electromagneti…
The Axidental Universe
Thomas C. Bachlechner, Kate Eckerle, Oliver Janssen +1
Theories with several hundred axion fields have enormous numbers of distinct meta-stable minima. A small fraction of these local minima have vacuum energy compatible with current m…
Black Hole Entropy in General Relativity
Thomas C. Bachlechner
The Bekenstein-Hawking formula relates the black hole entropy and horizon area. Semiclassical entropy computations have relied on an action principle that fixes a gauge dependent a…
Axion Landscape Cosmology
Thomas C. Bachlechner, Kate Eckerle, Oliver Janssen +1
We study the cosmology of complex multi-axion theories. With O(100) fields and GUT scale energies these theories contain a vast number of vacua, inflationary trajectories and a nat…
Vacuum Decay in General Relativity
Thomas C. Bachlechner
We provide a novel, concise and self-contained evaluation of true- and false vacuum decay rates in general relativity. We insist on general covariance and choose observable boundar…
