Planck 2018 Memorial Scientific Symposium

10 Oct 2018, 09:00 → 11 Oct 2018, 16:00 Europe/Budapest

The “Planck 2018 Memorial Scientific Symposium” is organized on the occasion of Max Planck’s 160th birthday and of the 100th anniversary of his receiving the Nobel Prize in Physics. The elementary quantum of action h discovered by Planck in the year 1900 plays a fundamental role not only in physics (from microphysics to cosmological physics), but in other natural sciences (like chemistry or biology) and modern technologies (like microelectronics), as well as in our everyday life. Max Planck was elected to a honorary member of the Hungarian Academy of Sciences, and this is an other reason for why the Joint Committee of the History of Science and Technology celebrates the Great Master on this outstanding occasion.

At this two-days memorial scientific symposium there will be 45 minutes plenary talks on each day. Besides emphasizing historical aspects and the broad spectrum of Max Planck’s contribution to physics, the alltogether eleven talks to be delivered by leading experts, are also ment to reflect the present challenges for human knowledge concerning the scientific description of nature.

5 The symplectic camel property and quantum mechanics: old and new results.

The variability of physical "constants" is a possibility that cannot be out-ruled and which is an active area of research in cosmology and astrophysics. In fact, since Dirac in his "Large Numbers Hypothesis" suggested that some constants of Nature could vary in space and time, the topic has fascinated not only physicists but also philosophers of Science and has motivated numerous theoretical and experimental researches. In this talk, we focus on some consequences of possible changes in Planck's constant. In particular, the purity of a quantum state is extremely sensitive to such changes, and quantum states can evolve into classical states, and vice versa. We also shortly discuss entanglement from this perspective. A complete classification of such transitions is however not possible for the moment being because of yet unsolved mathematical difficulties related to the study of positivity properties of trace class operators.
