Replacing Anthropy with entropy: Does it work?
Irit Maor, Thomas W. Kephart, Lawrence M. Krauss +2
Probably not, because there are lots of manifestly unanthropic ways of producing entropy. We demonstrate that the Causal Entropic Principle (CEP), as a replacement for the anthropi…
The Aharonov-Bohm effect for a knotted magnetic solenoid
Roman V. Buniy, Thomas W. Kephart
We show that the linking of a semiclassical path of a charged particle with a knotted magnetic solenoid results in the Aharonov-Bohm effect. The phase shift in the wave function is…
What is the entropy of the universe?
Paul Frampton, Stephen D. H. Hsu, Thomas W. Kephart +1
Standard calculations suggest that the entropy of our universe is dominated by black holes, whose entropy is of order their area in Planck units, although they comprise only a tiny…
Higher order topological invariants from the Chern-Simons action
Roman V. Buniy, Thomas W. Kephart
It is well known that for a field theory with the Chern-Simons action, expectation values of Wilson line operators are topological invariants. The standard result is expressed in t…
Higher order topological actions
Roman V. Buniy, Thomas W. Kephart
In classical mechanics, an action is defined only modulo additive terms which do not modify the equations of motion; in certain cases, these terms are topological quantities. We co…
A proposal for detecting second order topological quantum phase
Roman V. Buniy, Thomas W. Kephart
Gaussian linking of a semiclassical path of a charged particle with a magnetic flux tube is responsible for the Aharonov-Bohm effect, where one observes interference proportional t…
