... No new resources will be required. This course is one of four new one-semester, three credit hour courses which will replace five three credit hour courses currently offered; Physics 405,407,412,414 and 455. Physics 420 however, will be taught once each year, rather than every two years; hence the t ...
Consciousness and Quantum Theory: Strange Bedfellows Barry Loewer
... The nature of consciousness and the interpretation of quantum mechanics are two subjects that excite great interest. Even more exciting then is the idea percolating through certain quarters that there are deep and significant connections between the two. Among those who have advocated a quantum mech ...

Quantum fluctuations can promote or inhibit glass formation
... Glasses are dynamically arrested states of matter that do not exhibit the long-range periodic structure of crystals1–4 . Here we develop new insights from theory and simulation into the impact of quantum fluctuations on glass formation. As intuition may suggest, we observe that large quantum fluctua ...
