Quantum Sciences Seminar Series - David DiVincenzo, RWTH Aachen - "Engineering the Solid State Quantum Computer"

Mon, Jul 15, 2013, 1:30 pm to 2:30 pm
Progress on solid state qubits, particularly Josephson junction devices, now brings us to the possibility of planning a scalable, multi-qubit architecture.  While we can envision how the quantum part of device can be designed to effectively implement fault tolerant error correction, I will argue that, if implemented with present-day techniques,...

Fri, May 31, 2013, 4:30 pm to 5:30 pm
We take a look at different ways to inspire interest in the physics of renewable energy technologies and how to start students on the road to challenge how the world perceives energy use.

Atomic Physics Seminar - M.Fertl, Paul Scherrer Inst. - A progress report on the neutron electric dipole moment experiment at the Paul Scherrer Inst.

Results of a Dark Matter Search with the Silicon Detectors of the CDMS II Experment - Enectali Figueroa-Feliciano, MIT

HET Informal Seminar - IAS - Narayan Krishnan, Chennai Mathematical Institute - D-brane Plane Waves, Hyperscaling Violation and Entanglement Entropy

High Energy Theory Seminar - Radu Roiban, Penn State - On the one-loop S matrix of certain reduced supersymmetry supergravity theories

Fri, May 17, 2013, 1:30 pm to 2:30 pm
We construct all supergravity theories that can be obtained through factorized projections of N = 8 supergravity, exposing their double-copy structure, and calculate their one-loop four-point scattering amplitudes.

High Energy Theory Seminar - IAS - Josef Pradler, Johns Hopkins University - Dark Photons in Cosmology, Astrophysics and Experiment

Tue, May 14, 2013, 1:30 pm to 2:30 pm
Light new particles with masses well below the GeV-scale are an often considered and plausible extension of the Standard Model. In this talk I will present new results on dark photons, a massive vector boson kinetically mixed with the photon.

High Energy Theory Seminar - IAS - Alexander B. Zamolodchikov, Rutgers, The State University NJ - Classical Conformal Block and Painleve VI

Mon, May 13, 2013, 2:30 pm to 4:00 pm
Classical conformal blocks appear in the limit c->infinity ofthe Virasoro conformal blocks. Classical conformal blocks have close relationship to monodromy of the second order differential equations with regular singularities. I will discuss relation of 4-point classicalconformal blocks to special solutions of Painleve VI equation.

Condensed Matter Seminar, Liang Fu, MIT, From Topological Crystalline Insulator to Anderson Transition

Mon, May 13, 2013, 1:15 pm to 2:30 pm
Structure and symmetry play important roles in determining electronic properties of periodic solids. The interplay between crystalline symmetry and electronic topology leads to new phases of matter dubbed topological crystalline insulators, which possess protected surface states with unique and tunable electronic properties.

High Energy Theory Seminar - IAS - Thomas Faulkner, IAS - “The Entanglement Renyi Entropies of Disjoint Intervals in AdS/CFT”

Fri, May 10, 2013, 1:30 pm to 2:30 pm
I will discuss how to compute Entanglement Renyi Entropies for two dimensional holographic CFTs using AdS_3 handlebody solutions. Some simplifying assumptions are made. The answer I find is consistent with the Ryu-Takayanagi prediction for Entanglement Entropy.

Math Physics Seminar, Alessandro Giuliani, University of Rome, Striped states at the ferromagnetic transition

Tue, May 7, 2013, 4:30 pm to 6:00 pm
We consider a two-dimensional Ising model with nearest neighbor ferromagnetic and long-range, power-law decaying, antiferromagnetic interactions. We assume that the decay exponent of the antiferromagnetic part is larger than 4.

PCTS Series “Nonequilibrium Physics with Strongly Interacting Matter and Light” presents

Mon, May 6, 2013, 2:00 pm to Wed, May 1, 2013, 3:00 pm
Several mean-field computations have revealed the existence of an out of equilibrium dynamical transition induced by quantum quenching an isolated system starting from its symmetry broken phase. In this talk I shall present results obtained for the quantum O(N) field theory in the large N limit by taking into account dynamical fluctuations at the...

PCTS Series “Nonequilibrium Physics with Strongly Interacting Matter and Light” presents: Quantum quenches, dynamical transitions and off-equilibr

Fri, May 3, 2013, 2:00 pm to 3:15 pm
Several mean-field computations have revealed the existence of an out of equilibrium dynamical transition induced by quantum quenching an isolated system starting from its symmetry broken phase. In this talk I shall present results obtained for the quantum O(N) field theory in the large N limit by taking into account dynamical fluctuations at the...

Hamilton Colloquium Series - Eliot Quataert, University of California-Berkeley - "The Physics of Galaxy Cluster Plasmas"

Thu, May 2, 2013, 4:30 pm to 5:30 pm

Galaxy clusters are among the largest gravitationally bound objects in the universe. The majority of the baryonic mass in clusters resides in a hot, low density plasma that pervades the intracluster medium (rather than in stars).

Condensed Matter LUNCH Seminar, Chen Fang, PU and Suyang Xu, PU

Wed, May 1, 2013, 12:00 pm to 1:00 pm
Chen Fang will discuss Crystalline Topological Insulators SuYang Xu will discuss Protected & Broken Symmetries in TIs

Math Physics Seminar, Hugo Duminil, U of Geneva, Parafermionic observables in planar Potts models and Self Avoiding Walks

Tue, Apr 30, 2013, 4:30 pm to 6:00 pm
In this talk, we will discuss the role of parafermionic observables in the study of several planar statistical physics models. These objects have been introduced recently by Smirnov and Cardy and have been instrumental in Smirnov's proof of conformal invariance of the Ising model.

Special Condensed Matter Seminar, Kai Sun, U of Michigan at Ann Arbor, Kondo insulators: insulator, metal or topological insulator?

Tue, Apr 30, 2013, 3:30 pm to 5:00 pm
In the last few decades, various puzzles have emerged in the study of strongly-correlated materials. In a family of strongly-correlated insulators, known as Kondo insulators, one such long-standing puzzle has remained open for over 40 years.
