Most takes on quantum field theory start from microscopics, fundamental degrees of freedom, a Lagrangian. Conformal field theory is an exception—it focuses on the algebra of local operators and avoids any reference to the Lagrangian. This leads to a method for doing practical CFT calculations—the conformal bootstrap.

## Donald R. Hamilton Colloquium

### Hamilton Colloquium Series - Slava Rychkov, CERN, and ENS-Paris, “Non-Hamiltonian approach to conformal quantum field theory – 40 years later”

### Hamilton Colloquium Series - Michael Gordin, Dept. of History, Princeton, “Einstein in Bohemia: Not-So-General Relativity, 1911-1912”

In the spring of 1911, Albert Einstein moved from Zurich to the German University in Prague, taking up his first appointment as a full professor. Heavily on his mind was a project to extend the special theory of relativity (1905) to a general theory of relativity, building from his 1907 inspiration on the equivalence of inertial and...

### Hamilton Colloquium Series- Leslie Rosenberg, University of Washington, "Searching for Dark-Matter Axions"

The axion is a hypothetical elementary particle whose existence would explain the baffling absence of CP violation in strong interactions. Axions also happen to be a compelling dark-matter candidate. Even if dark-matter axions were to comprise the overwhelming majority of mass in the universe, they would be extraordinarily difficult to detect...

### Hamilton Colloquium Series- David Huse, Princeton University, "Quantum thermalization, many-body Anderson localization, and the entanglement frontier"

Progress in physics and quantum information science motivates much recent study of the behavior of extensively-entangled many-body quantum systems fully isolated from their environment, and thus undergoing unitary time evolution. What does it mean for such a system to go to thermal equilibrium?

### Hamilton Colloquium Series - Thomas Gregor, Princeton, "Precision and reproducibility in development"

### Hamilton Colloquium Series - Matthew P.A. Fisher, UC-Santa Barbara, "Quantum Tapestries"

### Hamilton Colloquium Series - Yayu Wang, Tsinghua University, "Quantum Anomalous Hall Effect in Topological Insulators"

The anomalous Hall effect was discovered more than 130 years ago in a ferromagnet, where a Hall resistance exists even in the absence of an external magnetic field. The quantized version of the anomalous Hall effect has attracted much interest since the discovery of quantum Hall effect in the 1980s.

### Hamilton Colloquium Series - Mikhail Lukin, Harvard University, "Quantum Dynamics of Strongly Interacting Systems"

We will discuss recent developments at a new scientific interface involving quantum many-body dynamics of strongly interacting systems. Combining advances in several sub-fields of physical science, this research is aimed at realizing new states of matter that can exist far from equilibrium, and exploring novel science and applications of such...

### Hamilton Colloquium Series - Matthias Troyer, ETH Zurich: "Validating Quantum Devices"

### Hamilton Colloquium Series - Michael Peskin, Stanford U.: "Beyond the Higgs Boson: Further questions and expectations for the Large Hadron Collider"

### Hamilton Colloquium Series - Stanislas Leibler, The Rockefeller University, and IAS: "Ethology and Ecology of Simple Microbial Systems"

### Hamilton Colloquium Series - Jun Ye, University of Colorado: "Ultracold Molecules - New Frontiers in Quantum and Chemical Physics"

Molecules cooled to ultralow temperatures provide fundamental new insights to molecular interaction dynamics in the quantum regime.

### Hamilton Colloquium Series - Gabriel Orebi Gann, UC-Berkeley: "Here Be Dragons: Mysteries of the Neutrino" - Updated

Neutrinos are one of the most fascinating particles that occur in nature: hundreds of millions of times smaller than the proton, the neutrino was once thought to be massless and to travel at the speed of light.

### Hamilton Colloquium Series - Philip W. Anderson, Princeton University: "The Discovery of the Anderson-Higgs Mechanism"

### Hamilton Colloquium Series - Emilia Morosan, Rice University: "Exotic superconductivity at the itinerant-to-local moment crossover"

### Hamilton Colloquium Series - Joseph Polchinski, KITP, University of California-Santa Barbara: "The Black Hole Information Paradox: Alive and Kicking"

### Hamilton Colloquium Series - Cristiano Galbiati, Princeton University: "What about dark matter?"

I will discuss the status of direct dark matter searches and the prospects for the DarkSide program.

### Hamilton Colloquium Series - Sarah Eno, University of Maryland: "The LHC: Beyond the Standard Model"

The Higgs was postulated, during the 1970s, to be the source of electroweak symmetry breaking in the standard model. For my entire professional career, the search for the Higgs boson has been the highest priority goal for the field of experimental high energy physics.
