The lack of gluino signals in existing LHC data makes Dirac gauginos more motivated in weak scale SUSY phenomenology. I will describe a solution to a long-standing challenge in Dirac Gaugino model building, namely, how to avoid ubiquitous tachyons charged under the Standard Model gauge symmetries. I will also briefly discuss a simple realization…

Moonshine in mathematics originally referred to unexpected connections between the modular J function and the representation theory of the Monster, the largest sporadic finite group. Recently new kinds of moonshine have been discovered connecting other sporadic groups such as the Mathieu group M24 and Thompson's sporadic group to the mock theta…

Fermilab has entered an exciting new phase, in which an international collaboration is designing and building the world’s most powerful source of neutrinos on the Fermilab site. The neutrinos will be shot through the earth to the Homestake mine in South Dakota, where DUNE, a giant detector based on 40,000 tons of instrumented liquid argon 4700…

June 17 Jadwin Hall, Room A-10 Princeton University Department of Physics ~ Special Colloquium “Neutrinos are Everywhere: Towards a New Understanding of the Quantum Universe ” Speaker: Nigel S. Lockyer, Director Fermi National Laboratory Fermilab has entered an exciting new phase, in which an international collaboration is designing and…

The intriguing many-body phases of quantum matter arise from the interplay of particle interactions, spatial symmetries, and external fields. Generating these phases in an engineered system could provide deeper insight into their nature and the potential for harnessing their unique properties. However, concurrently bringing together the main…

Spatial symmetries in crystals are distinguished by whether they preserve the spatial origin. I will show how this basic geometric property gives rise to a new topology in band insulators, which we propose (and subsequently discover) to lie in the large-gap insulators: KHgX (X=As,Sb,Bi). These insulators are described by generalized symmetries…

One of the distinctive characteristics of strongly interacting and correlated quantum systems is the non-trivial interplay between low- and high-energy degrees of freedom. The origin of this interplay lies in the electron-electron and electron-boson interactions, which spread the optical spectral weight over a wide energy range. To address this…

Higher-Order Results from BlackHat I review the on-shell approach to loop amplitudes, and its implementation in the BlackHat library. I present a selection of recent calculations done using the library. These include next-to-leading order calculations of electroweak vectors accompanied by multiple jets, and of vector pairs accompanied by…

Description: The goal of this discussion will be to first provide a broader picture and then to discuss the most recent work. I will review the general features of Low energy expansion of stringy amplitudes (tree level and one-loop) and it's relation to number of non-compact dimensions. Then I will show how it is possible to extract low lying…

“Searching for New Phenomena at the Intensity Frontier” Abstract In February of this year the intensity frontier SuperKEKB e+e- collider, located at the KEK laboratory in Tsukuba, came online with its “first turns”, a major milestone in preparing for collisions in 2017. The Belle II detector, located at the SuperKEKB interaction point, will be…

Description: I will discuss the discrete Liouville theory and its connection with cluster algebras, Teichmuller theory and supersymmetric gauge theories. References: The version of discrete Liouville I discuss has been formulated by many papers by Faddeev, Volkov, Takhajan, Kashaev. A good starting point is: Faddeev, Kashaev, Volkov hep…

Complex quantum many-body systems are ubiquitous in nature, yet their behaviour often remains very challenging to predict with analytical or numerical calculations - especially when it comes to dynamics. However, using ultracold atoms in optical lattices it is possible to create precisely tunable, yet very accessible complex systems, which can be…
