Hamilton Colloquium Series, Immanuel Bloch, Max Planck Institute of Quantum Optics & LMU Munich, "New Avenues for Quantum Simulations with Atoms, Molecules and Photons", April 13, Jadwin A10
Thu, Apr 13, 2023, 4:00 pm5:00 pm

40 years ago, Richard Feynman outlined his vision of a quantum simulator for carrying out complex calculations of physical problems. Today, his dream has become a reality and a highly active field of resarch across different platforms ranging from ultracold atoms and ions, to superconducting qubits and photons. In my…

Hamilton Colloquium Series, Tadashi Takayanagi, Yukawa Institute for Theoretical Physics, "Holography with End-of-the-World Branes and Quantum Entanglement", Feb 28, Jadwin A10
Tue, Feb 28, 2023, 4:00 pm5:00 pm

Holography relates quantum many-body systems to gravitational theories. Quantum entanglement plays a key role to explain how the spacetime geometries in gravity emerge from quantum systems. A new class of holography can be found by introducing so called end-of-the-world branes and has been actively studied recently. Such holographic models…

Hamilton Colloquium Series, Nathaniel Craig, Univ of CA/Santa Barbara, "The “Who Ordered That” Collider", Feb 23, Jadwin A10
Thu, Feb 23, 2023, 4:00 pm5:00 pm

 

 In this talk, I’ll survey some of the major open questions in particle physics and make the case that they can best be addressed by a qualitatively new type of particle accelerator: a high-energy muon collider.  Recent progress on long-standing accelerator and detector challenges make such a collider a compelling…

Hamilton Colloquium Series, Xavier Trepat, Institute for Bioengineering of Catalonia, "Linking Force, Form and Function in Intestinal Organoids", Feb 16, Jadwin A10
Thu, Feb 16, 2023, 4:00 pm5:00 pm

Intestinal organoids capture essential features of the intestinal epithelium such as crypt folding, spatial compartmentalization of different cell types, and cellular movements from crypt to villus. Each of these processes and their coordination in time and space requires patterned physical forces. I will present maps of the three-dimensional…

Hamilton Colloquium Series, Ramesh Narayan, Harvard University, "The Black Hole at Our Galactic Center" , Jadwin A10
Thu, Feb 9, 2023, 4:00 pm5:00 pm

At the center of our Milky Way Galaxy lives a compact massive object called Sagittarius A* (Sgr A*) which is believed to be a black hole. Its mass, as inferred from the orbits of gravitationally bound stars as well as from direct images obtained by the Event Horizon Telescope, is 4 million solar masses. Gas accreting gravitationally on Sgr A*…

Hamilton Colloquium Series, Laura Cadonati, GA Tech, "Exploring the Universe with Gravitational Waves" February 2, Jadwin A-10
Thu, Feb 2, 2023, 4:00 pm5:00 pm

A new era in astrophysics was inaugurated with the 2015 discovery of gravitational waves from the collision of two black holes in data from the Laser Interferometer Gravitational-wave Observatory (LIGO). Since then, LIGO and its sister project Virgo have observed several more gravitational waves from the collision of black holes and neutron…

Hamilton Colloquium Series, Kaushik Bhattacharya, Caltech, "Liquid Crystals Meet Elastomers"", Jadwin A-10
Tue, Dec 13, 2022, 4:00 pm5:00 pm

Liquid crystal elastomers are rubbery solids with liquid crystal mesogens incorporated into their polymer chains.  These solids combine the entropic elasticity of rubber with the orientational phase transitions of liquid crystals.  The deformation and orientational order are coupled, giving rise to a rich variety of phenomena…

Hamilton Colloquium Series, Roland Bauerschmidt, University of Cambridge"Different Perspectives in Statistical Physics" Jadwin A-10
Thu, Dec 1, 2022, 4:00 pm5:00 pm

The use of different perspectives on a problem is a very powerful principle in statistical physics, and has been especially important in mathematical physics. I will illustrate this theme with old and recent applications. These include the interpretation of QFTs at imaginary time as statistical fields, the relation of statistical fields to…

Hamilton Colloquium Series, Leonardo Rastelli, Stony Brook University, "Positivity Constraints on Theory Space", Jadwin A-10
Tue, Nov 8, 2022, 4:00 pm5:00 pm

The bootstrap program leverages symmetry and positivity to carve out the space of consistent quantum theories. In this talk I will highlight some of its recent successes, ranging from the numerical solution of statistical models at criticality to universal constraints on quantum gravity.

Thu, Oct 6, 2022, 4:00 pm5:00 pm

Finding unconventional superconductors in proximity to various strongly correlated electronic phases has been a recurring theme in materials as diverse as heavy fermion compounds, cuprates, pnictides, and twisted bilayer graphene. The recent discovery of superconductivity in layered nickelates1 was motivated by looking for an analog of the…

Hamilton Colloquium Series, Marc Kamionkowski, Johns Hopkins University, "News from Cosmic Dark Sectors"
Wed, Apr 27, 2022, 4:00 pm4:00 pm

Cosmologists are proud of the standard cosmological model that has been developed to account for a wealth of disparate features of the Universe. The model requires, though, that we postulate the existence of some collisionless dark matter and also dark energy, a negative-pressure substance. The nature of both of these dark constituents is a…

Thu, Apr 14, 2022, 4:00 pm4:00 pm

The study of hyperuniform states of matter is an emerging multidisciplinary field, influencing and linking developments across the physical sciences, mathematics and biology. The hyperuniformity concept generalizes the traditional notion of long-range order to include not only all crystals and quasicrystals,…

Hamilton Colloquium Series, Netta Engelhardt, MIT, "The Black Hole Information Paradox in the Age of Holographic Entanglement Entropy"
Thu, Mar 31, 2022, 4:00 pm4:00 pm

The black hole information paradox — whether information escapes an evaporating black hole or not — remains one of the greatest unsolved mysteries of theoretical physics. The apparent conflict between validity of semiclassical gravity at low energies and unitarity of quantum mechanics has long been expected…

Hamilton Colloquium Series, Subir Sachdev, Harvard University, "Planckian Metals and Black Holes"
Thu, Nov 11, 2021, 4:00 pm4:00 pm

Many modern materials feature a “Planckian metal”: a phase of electronic quantum matter without quasiparticle excitations, and relaxation in a time of order Planck's constant divided by the absolute temperature. The semiclassical theory of black holes predicts thermodynamic properties which are difficult to…
