Physics Colloquium

The Physics Department colloquia are held on Mondays at 4:15pm in 428 Pupin Hall.  Prior to the colloquia Coffee Hour is served starting at 3:30pm on the 7th floor in 705 Pupin.

Colloquia are scheduled during the academic year. They are not held during the summer months.

"Unlocking the secrets of the fastest fluid in nature"

Fluid dynamic behavior is observed in radically different systems, ranging from ordinary fluids (such as water) to their exotic counterparts formed in ultra-relativistic particle collisions and the strongly interacting matter formed in neutron star mergers.

"Schrödinger Cats, Maxwell’s Demon and Quantum Error Correction (That Works)"

A ‘second quantum revolution’ is underway based on our new understanding of how information can be stored and manipulated using quantum hardware.  Even more remarkable than the concept of quantum computation is the concept of quantum error correction.   We know that measurement disturbs a quantum state.  Nevertheless, it is possible to store an unknown quantum state and if it

"The Social Life of Heavy Quarks"

"The Social Life of Heavy Quarks"

I will discuss recent developments regarding new types of hadrons involving heavy quarks: hadronic molecules, doubly heavy baryons, stable tetraquarks and others. I will also explain how the discovery of the doubly heavy baryon leads to quark-level analogue of nuclear fusion, with energy release per reaction an order of magnitude greater than in ordinary fusion.
