High Energy Theory Seminar - Tolya Dymarsky, Cambridge - On the four-point correlation function of the stress-energy tensor in a CFT

Tue, Apr 30, 2013, 2:00 pm to 3:30 pm
We discuss to what extent the full set of symmetries, i.e. conformal symmetry and general diffeomorphisms constraint the form of the four-point correlation functions of stress-energy tensors and conserved currents in a general conformal field theory.

High Energy Theory Seminar - Xi Yin, Harvard - A low temperature expansion for supersymmetric matrix quantum mechanics

Condensed Matter Seminar - Jeremy Levy, University of Pittsburgh, Oxide Nanoelectronics On Demand

Mon, Apr 29, 2013, 1:15 pm to 2:30 pm
Electronic confinement at nanoscale dimensions remains a central means of science and technology. I will describe a novel method for producing electronic nanostructures at the interface between two normally insulating oxides, LaAlO3 and SrTiO3.

Mon, Apr 29, 2013, 12:00 pm to 1:00 pm

Lunch @ 11:45, talk @ 12-1:00
Audience: Physics faculty, post docs, grads

Hamilton Lecture - Joe Incandela, University of California-Santa Barbara and CERN, "The Search for the Higgs Boson: Discovery at the LHC"

Thu, Apr 25, 2013, 8:00 pm to 10:00 pm

The Large Hadron Collider (LHC) at CERN near Geneva Switzerland has performed spectacularly well in its first major running period from December 2009 through February 2013. Data of unprecedented quality and quantity have been recorded for proton-proton collisions at energies of 7 and 8 Trillion electron Volts – the highest energies ever...

Special PCTS Seminar - Horacio Casini, Centro Atomico Bariloche - Physical entanglement entropy: relative entropy and mutual information

Wed, Apr 24, 2013, 2:30 pm to 4:00 pm
I will describe general facts about entanglement entropy in QFT and discuss two different ways to get rid of the regularization ambiguities, using mutual information and relative entropy. Then i will show relative entropy gives a proof of a well defined version of the Bekenstein bound, an offer a strong test to holographic entropy.

Informal HET Seminar - IAS-Ken Intriligator, U. of California, San Diego - Aspects of Three Dimensional N=2 Chern Simons Matter Field Theories

High Energy Theory Seminar - IAS - Gerald Gabrielse, Harvard University - ACME: Obtaining an Electron Electric Dipole Moment from ThO

Mon, Apr 22, 2013, 2:30 pm to 3:30 pm
The electron edm is an important constraint on extensions to the Standard Model such as supersymmetric models. ACME is closing in on a more sensitive measurement of this moment, profiting from the huge electric field within the ThO molecule.

Mon, Apr 22, 2013, 1:15 pm to Mon, Apr 15, 2013, 2:30 pm


Condensed Matter Seminar, Oleg Tchernyshyov, Z_2 spin liquid in the Heisenberg antiferromagnet on kagome

Mon, Apr 22, 2013, 1:15 pm to 2:30 pm
A spin liquid is a hypothetical quantum ground state of a frustrated Heisenberg magnet conjectured by P.W. Anderson in the 1970s. Its distinguishing features are (1) a lack of magnetic order and (2) a degeneracy that depends on the topology of the system.

Ben de Bivort (Harvard) "The Neurobiology of Individuality"

Mon, Apr 22, 2013, 12:00 pm to 1:00 pm

25th Annual Physics Recital

Sat, Apr 20, 2013, 6:00 pm to 8:00 pm

There will be a reception immediately following in the Joseph Henry Room, Jadwin Hall.

High Energy Theory Seminar - IAS - Jonathan Maltz, Stanford University - Light States in Chern-Simons Matter Theory Coupled to Fundamental Matter

"Fundamental Physics and the LHC: A Progress Report"-Nima Arkani-Hamed- IAS

Wed, Apr 17, 2013, 4:00 pm to 5:00 pm
"Last July's discovery of the Higgs particle at the Large Hadron Collider was a triumph for both experiment and theory in fundamental physics. But the Higgs also introduces major conceptual paradoxes that strongly suggest we are missing essential new physical principles.

Raymond & Beverly Sackler Lecture in Astrophysics, Bill Jones "The Universe in a New Light: The First Cosmological Results from the PLANCK Mission"

Tue, Apr 16, 2013, 8:00 pm to 10:30 pm

The precision and accuracy of the recently released Planck data are without precedent; the data from a single experiment provide all-sky images at wavelengths never before explored, covering more than three decades in angular scale with a signal dynamic range exceeding a factor of a million.

Audience: Free and open to the public

Math Physics Seminar - Vieri Mastropietro, Univ of Milan, Italy, Universal finite size corrections and the central charge in non solvable Ising models

Tue, Apr 16, 2013, 4:30 pm to 6:00 pm
We investigate a non solvable two-dimensional ferromagnetic Ising model with nearest neighbor plus weak finite range interactions. We rigorously establish one of the predictions of Conformal Field Theory (CFT), namely the fact that at the critical temperature the finite size corrections to the free energy are universal.

Condensed Matter Seminar, Young S. Lee, MIT, Two faces of the kagomé lattice: quantum spin liquids and topological flat bands

Mon, Apr 15, 2013, 1:15 pm to 2:30 pm
I will describe experimental studies of new states of magnetism on the S=1/2 kagomé lattice. In particular, I will discuss results on two materials: one with antiferromagnetic exchange (herbertsmithite) and one with ferromagnetic exchange (Cu(1,3-bdc)).

King-Wai Yau (Johns Hopkins) "Responses to Single Photons in Vision and to Single Odorant Molecules in Olfaction, and Their Implications"

Mon, Apr 15, 2013, 12:00 pm to 1:00 pm

High Energy Theory Seminar - Tatsuma Nishioka, Princeton University - "Entanglement Entropy and RG Flow"

Hamilton Colloquium Series - Frank Jenko, Max-Planck-Institut für Plasmaphysik - "Exploring the Mysteries of Plasma Turbulence"

Thu, Apr 11, 2013, 4:30 pm to 5:30 pm
Plasma turbulence is a ubiquitous phenomenon, influencing the dynamics in most of the visible universe and playing a crucial role in countless experiments of basic and applied plasma science. Its comprehension and control is a prerequisite to the realization of fusion energy.
