Professor Andrew Strominger Participates in Press Conference to Promote Dr. Stephen Hawking's Final Book Release

October 24, 2018

On October 15, 2018, Professor Andrew Strominger participated in a panel discussion at the launch of the late Dr. Stephen Hawking's final book, Brief Answers to the Big Questions. The book was published posthumously witht he help of Dr. Hawking's family, friends, and collaborators. Other members of the panel included Dr. Hawking's children Timothy Hawking and Lucy Hawking; Malcolm Perry, close collaborator and fellow Professor of Physics at the University of Cambridge; and Fay Dowker, Professor of Theortetical Physics from the Imperial College London. The panel was chaired by...

Latest work of Professor Cumrum Vafa Implies that Dark Energy's Value Changes

October 17, 2018

 

"Harvard physicist Cumrun Vafa is one of string theory’s strongest proponents. But this summer, other string theorists have been reeling from his latest conjecture, which might invalidate their ideas built on a decade-long assumption that dark energy is constant. Vafa’s work implies that dark energy’s value changes.

A non-constant dark energy is a consequence of Vafa and his collaborators’ attempts to apply string theory to a universe like ours—one where the very vacuum of space appears to have some innate energy. If his conjecture (and string theory itself)...

Darkness Visible - Shedding New Light on Black Holes: A Panel Discussion with Cumrun Vafa

June 8, 2018

This year, Professor Cumrun Vafa was invited to speak at the World Science Festival on a panel discussion titled "Darkness Visible: Shedding New Light on Black Holes." Moderated by the Chairman of the Board of the World Science Festival and Professor of Physics and Mathematics at Colombia University, Brian Greene, Professor Vafa is introduced to the program at 1:13:00.

Black holes may hold the key to understanding the most fundamental truths of the universe, but how do you see something that’s, well, black? Astronomers think they...

The Complete Lifetime of the Standard Model

April 3, 2018

 

In a classically scale-invariant quantum field theory, tunneling rates are infrared divergent due to the existence of instantons of any size. While one expects such divergences to be resolved by quantum effects, it has been unclear how higher-loop corrections can resolve a problem appearing already at one loop. With a careful power counting, graduate student Anders Andreassen, 2017 Harvard PhD William Frost, and Prof. Matthew Schwartz uncover a series of loop contributions that dominate...
