Nov 4, 2021 · As part of the Fall 2021 Bethe Lecture Series at Cornell, Professor Andrew Strominger, Gwill E. York Professor of Physics at Harvard University presents 'Probing the Edges of the Universe: Black Holes, Horizons and Strings'.
May 29, 2021 · w (1+infinity) and the Celestial Sphere. Andrew Strominger. It is shown that the infinite tower of tree-level soft graviton symmetries in asymptotically flat 4D quantum gravity can be organized into a single chiral 2D Kac-Moody symmetry based on the wedge algebra of w (1+infinity). The infinite towers of soft photon or gluon symmetries also ...
Dec 21, 2016 · Harvard’s Cumrun Vafa, the Donner Professor of Science, and Andrew Strominger, the Gwill E. York Professor of Physics, have been named winners of the 2017 Breakthrough Prize in Fundamental Physics in recognition of their groundbreaking work in a number of areas, including black hole theory, quantum gravity, and string theory.
Thirty-five years ago string theory took physics by storm, promising the coveted unified theory of nature’s forces that Einstein valiantly sought but never f...

Jun 6, 2016 · As Strominger showed , if one takes the limit as the photon energy goes to zero (that is, the photon becomes “soft,” with vanishing energy), the result is a new state, which can be called a new vacuum because it has essentially the same energy as the original vacuum state. The first vacuum is turned into the second by acting with an operator that is just the quantum version of the new ...
Jun 22, 2017 · Black Hole Information Revisited. Andrew Strominger. We argue that four-dimensional black hole evaporation inevitably produces an infinite number of soft particles in addition to the thermally distributed `hard' Hawking quanta, and moreover that the soft and hard particles are highly correlated. This raises the possibility that quantum purity ...
Apr 17, 2020 · Andrew Strominger and his team have been conducting further research on black hole imaging. Kris Snibbe/Harvard file photo The fear, Strominger said, was that the image would only reveal information about the swirling, glowing stuff, which is mostly gases heated to billions of degrees and back-lit by light looping around and around and around.
