Search, discovery and measurements of the Higgs boson in the diphoton decay channel at CMS- Josh Bendavid, CERN

Thu, Feb 4, 2016, 1:30 pm to 2:30 pm
The observation of a new particle with properties consistent with a Standard Model Higgs boson by the ATLAS and CMS collaborations in 2012 marked a major achievement in particle physics, fulfilling a major goal of the LHC program. Continuing measurements of the properties of the new boson constitute stringent tests of the Standard Model in...

Top quarks & beyond: probing new physics at the Large Hadron Collider- Louise Skinnari, CERN

Tue, Feb 2, 2016, 2:00 pm to 3:00 pm
Abstract: The first run of the Large Hadron Collider has been a great success, most notably with the discovery of the Higgs boson. Despite the continued triumph of the Standard Model, important questions about how nature works on small scales remain unanswered. Top quarks play a central role in many extensions to the Standard Model proposed to...

Ultracold Quantum Matter of Strongly Dipolar Molecules - Sebastian Will, MIT

Thu, Jan 28, 2016, 1:00 pm to 2:00 pm
Over the past decade, atomic quantum gases have successfully been employed as quantum simulators for strongly correlated many-body systems. However, the interactions between ultracold atoms typically have short-range character, limiting the spectrum of quantum phenomena to be explored.

Tailoring the flow of light at the nanoscale with hyperbolic metasurfaces - Alex High, Harvard University

Wed, Jan 27, 2016, 1:00 pm to 2:00 pm
Metamaterials, artificial optical media composed of sub-wavelength metallic and dielectric building blocks, can significantly enhance our ability to tailor the flow of light at nanoscale dimensions. However, three-dimensional (3D) metamaterials suffer from extreme propagation losses, limiting their practical utility.

A Light Dark Side - Yonit Hochberg, Berkeley

Mon, Jan 25, 2016, 3:00 pm to 4:00 pm
The exploration of dark matter beyond the WIMP is of vital importance towards resolving the identity of dark matter. Focusing on light dark matter, I will demonstrate this from two perspectives. From the theory side, I will present a new candidate for thermal dark matter in the form of Strongly Interacting Massive Particles (SIMPs).

Special seminar - Hao Ding, Tsinghua U., Bejing: "Exploring high-temperature superconductivity in FeSe/TiO2(001) heterostructure"

Fri, Jan 22, 2016, 1:00 pm to 2:15 pm
Searching for new exotic quantum phenomena is one of the fundamental goals and driving forces of condensed matter physics. Recent advances in the atomic-scale controlled synthesis techniques enable us to design and fabricate heterostructures for generating new quantum states, such as the emergent high-temperature superconductivity (HTSC) in single...

Time-resolved optical probes of spin and valley physics in semiconductors - Luyi Yang, Los Alamos

Thu, Jan 21, 2016, 2:00 pm to 3:00 pm
dynamics of electrons and holes in semiconductors. The key to optical control is the strong spin-orbit selection rules that govern absorption near the bandgap, which permit photo-generation and detection of specific spin states (and in certain special cases, specific valley states).

Shaking up statistical physics in interacting quantum systems - Anushya Chandran, Perimeter Institute

Wed, Jan 20, 2016, 2:00 pm to 3:00 pm
Statistical mechanics is a central pillar of modern physics with applications across the sciences. At its core is the idea of thermal equilibrium, which allows for a simple description of an interacting quantum system in terms of a few properties like temperature, without keeping track of the entire wavefunction. But what if a quantum system fails...

Long-range entangled many-body states - Jeongwan Haah - MIT

Mon, Jan 18, 2016, 1:00 pm to 2:00 pm
A quantum entanglement is a special kind of correlation; it may yield a strong correlation that is not possible in a classical ensemble, or hide the correlation from all local observables. Especially important is the entanglement that arises from local interactions for its implications in many-body physics and future’s quantum technologies.

Symmetry protection in strongly interacting 3D bosonic systems - Fiona Burnell,

Thu, Jan 14, 2016, 1:00 pm to Mon, Jan 4, 2016, 2:00 pm
Recently, our classification of phases of matter has expanded to include “symmetry protected” phases, allowing us to identify multiple different phases with the same unbroken symmetry. In 3 spatial dimensions (3D), the different possible symmetry protected phases are closely related to 2D phases that cannot be realized with the corresponding...

Symmetry meets topological order - Meng Cheng, Microsoft Q

Tue, Jan 12, 2016, 1:00 pm to 2:00 pm
Abstract: Quantum matter in two spatial dimensions can exhibit topological order, which supports quasiparticles excitations with anyonic statistics and fractional symmetry quantum numbers, the latter of which is a manifestation of symmetry-enriched topological order. In this talk I will examine the interplay between global symmetry and...

Seeing through the haze: Constraining dark-matter annihilation in the presence of astrophysical point sources - Ben Safdi, MIT

Wed, Dec 9, 2015, 3:30 pm to 4:30 pm
Dark matter (DM) annihilating in the Milky Way and beyond may give rise to unique astrophysical signatures. However, these potential signs of new physics are easily confused with standard but poorly understood astrophysical backgrounds, such as populations of dim point sources like millisecond pulsars.
