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.

Colloquium organizer:  Brian Metzger bdm2129(at)columbia.edu

"Rattle and Shine: Joint Detection of Gravitational Waves and Light from the Binary Neutron Star Merger GW170817"

Monday, November 20, 2017 - 4:15pm

Edo Berger

Harvard University

"Rattle and Shine: Joint Detection of Gravitational Waves and Light from the Binary Neutron Star Merger GW170817"

The much-anticipated joint detection of gravitational waves and electromagnetic radiation was achieved for the first time on August 17, 2017, for the binary neutron star merger GW170817.  This event was detected by Advanced LIGO/Virgo, gamma-ray satellite

"GW170817 and neutron rich matter in the laboratory and in the heavens"

"GW170817 and neutron rich matter in the laboratory and in the heavens"

Compress almost anything to very high densities and electrons react with protons to make neutron rich matter.  This material is at the heart of many fundamental questions in nuclear physics and astrophysics.  What are the high-density phases of QCD?

"Coherent Coupling of Spin and Light"

Monday, December 11, 2017 - 4:15pm

"Coherent Coupling of Spin and Light"

Tremendous progress has been achieved in the coherent control of single quantum states (single charges, phonons, photons, and spins). At the frontier of quantum information science are efforts to hybridize different quantum degrees of freedom.

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

Monday, January 29, 2018 - 4:15pm

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

A revolution is underway in the construction of ‘artificial atoms’ out of superconducting electrical circuits. These macroscopic ‘atoms’ have quantized energy levels and can emit and absorb quanta of light (in this case microwave photons), just like ordinary atoms.
