In this article, you’ll learn everything concerning what a virtual office is and why you really want one. Good discussion of the unexpected features of vacuum energy and vacuum forces in little metal boxes (what we call rectangular cavities), such as the possibility of inward forces on one side and outward forces or zero force on other sides. It doesn’t go very fast, but we still call it the Casimir Drive. This classic paper is the first paper that proposed and studied a dynamical system with Casimir forces in it! The second stand-alone system involves energy storage in the form of batteries to produce electrical energy. The system was developed in 1995 and has been regularly criticised in the past decade. Over the past 200 million years, North America and Africa have been drifting apart. Using the squeezed light data collected over the last 20 years, we find that the restriction on negative vacuum energy is violated by most of the data, bringing into question the significance of quantum inequalities in quantum theory as well as the challenge of experimental verification of quantum inequalities. This paper is the only experimental test to date of a Quantum Inequality (QI), which is a restriction from quantum field theory on the concentration of negative vacuum energy over time and space.

This is the first description of media with a negative index of refraction of light in terms of quantized fields. The last gedanken experiment is about a box that shields the contents from gravitational fields of matter outside the box. The first gedanken experiment shows the impossibility of making a fixed surface that will be accelerated by the free vacuum fluctuations. 23. “Effect of quantum and thermal jitter on the feasibility of Bekenstein’s proposed experiment to search for Planck-scale signals,” G.J. Based on his valuable comments we expanded our investigation to include more thermal effects and expanded our collaboration to include LIGO expert Eric Black. We were very fortunate to have the comments and suggestions of Nobel Laureate Rainer Weiss on this paper. Done with my insightful thesis advisor, Lowell Brown, a student of Nobel Laureate Julian Schwinger, both very elegant in their physics. These books provide the best introduction to quantum physics and the role of quantum fluctuations you can get, with lots of physical insight and clear mathematics. 19. “Thrusting Against the Quantum Vacuum“, G.J. 10.

Maclay, S. Wadood, E. Black, and P. Milonni, Phys. This was written with my good friend Peter Milonni, quantum physicist extraordinaire, who has just published An Introduction to Quantum Optics and Quantum Fluctuations, Oxford University Press (2019). He also wrote the Quantum Vacuum, An Introduction to Quantum Field Electrodynamics, Academic Press. This paper, initiated by my long-time friend and collaborator Peter Milonni, analyzes an ingenious proposal by Jacob Beckenstein from Princeton, who started the field of the thermodynamics of black holes. University of Rochester graduate student Wadood Sultan, who was a pleasure to work with, was also part of our collaboration. It is an elegant study, and is the theoretical model implemented in the first MEMS device with Casimir forces made by Frederico Capasso, who wears some great ties, and collaborators when he was at Bell Labs. The MicroMed DeBakey ventricular assist device (VAD) functions as a “bridge to heart transplant” by pumping blood until a donor heart is available.

He’s being used to improve business, but his happiness dwindles and some in the sales department start to have a change of heart. Please note that visitor center hours are subject to change. Their initiatives frequently center on creating new goods or services, entering new markets, or boosting effectiveness and productivity. It studies the effectiveness of governmental expenditures, focusing primarily on the executive branch. 18. “A Gedanken spacecraft that operates using the quantum vacuum (Dynamic Casimir effect),” G.J. The above paper describes the first spacecraft that operates totally on energy from the quantum vacuum, using the excited vacuum for its drive. Notwithstanding that occasional gaseous fellow astronaut, smells in a spacecraft are as controlled as they can be. Whether it’s installation errors, compatibility problems, or functionality issues within the software suite, there are various avenues available for seeking help. This evidence of glacial activity showed just how much ice there was — about one-third of the world was under thick ice, for a grand total of 17 million cubic miles (71 million cubic km) of glacial ice. A pair of brazen thieves disguised themselves as police officers to break into the Gardner Museum in 1990. In 2017, the museum doubled its reward for return of the stolen paintings from $5 million to $10 million.
