The Harmonic Quantum Szilárd Engine
Paul Davies, Logan Thomas, George Zahariade
The Szilárd engine is a mechanism (akin to Maxwell's demon) for converting information into energy, which seemingly violates the second law of thermodynamics. Originally a classica…
A Heat Shield for de Sitter space
Paul Davies, Logan Thomas, George Zahariade
We investigate a quantum vacuum state for dimensional de Sitter space, corresponding to a region within a perfectly reflecting symmetric box of fixed physical size. We find…
Signatures of the Quantization of Gravity at Gravitational Wave Detectors
Maulik Parikh, Frank Wilczek, George Zahariade
We develop a formalism to calculate the response of a model gravitational wave detector to a quantized gravitational field. Coupling a detector to a quantum field induces stochasti…
Quantum Mechanics of Gravitational Waves
Maulik Parikh, Frank Wilczek, George Zahariade
For the purpose of analyzing observed phenomena, it has been convenient, and thus far sufficient, to regard gravity as subject to the deterministic principles of classical physics,…
Quantum Formation of Topological Defects
Mainak Mukhopadhyay, Tanmay Vachaspati, George Zahariade
We consider quantum phase transitions with global symmetry breakings that result in the formation of topological defects. We evaluate the number densities of kinks, vortices, and m…
The Noise of Gravitons
Maulik Parikh, Frank Wilczek, George Zahariade
We show that when the gravitational field is treated quantum-mechanically, it induces fluctuations -- noise -- in the lengths of the arms of gravitational wave detectors. The chara…
Emergence of classical structures from the quantum vacuum
Mainak Mukhopadhyay, Tanmay Vachaspati, George Zahariade
After a quantum phase transition the quantum vacuum can break up to form classical topological defects. We examine this process for scalar field models with symmetry for diff…
