Special Seminar: Shyam Shankar, Yale; “Drives, friction and measurements that preserve quantum coherence”

Thu, Dec 21, 2017, 1:30 pm

An open quantum system inevitably decoheres due to unwanted interactions with its dissipative environment. Such decoherence is a primary hurdle for constructing a large-scale quantum computer and much research is spent in “closing the system” i.e. improving qubit relaxation time, T1 and dephasing time, Tf.

Audience: A free lecture open to the public.

Special Seminar: Sanfeng Wu, MIT; "Topology and correlations in a monolayer crystal"

Wed, Dec 20, 2017, 1:30 pm

Topology and correlations are two fundamental aspects that determine the electronic ground states of condensed matter systems. Both aspects individually have led to striking observations such as the quantum spin Hall insulating state and superconductivity, respectively.


Special Seminar: Alexander Burgers, Caltech; "Engineering atom-light interactions in photonic crystal waveguides”

Tue, Dec 19, 2017, 1:30 pm

Integrating cold atoms with nanophotonics enables the exploration of new paradigms in quantum optics and many body physics. Advanced fabrication capabilities for low-loss dielectric materials provide powerful tools to engineer band structure and light-matter couplings between photons and atoms.

Audience: A free lecture open to the public.

Special Seminar: Hannes Bernien, Harvard; "Quantum LEGOs: Building large quantum systems atom-by-atom"

Mon, Dec 18, 2017, 1:30 pm

The realization of large-scale controlled quantum systems is an exciting frontier in modern physical science. In this talk, I will introduce a new approach based on cold atoms in arrays of optical tweezers. We use atom-by-atom assembly to deterministically prepare arrays of individually controlled cold atoms.

Audience: A free lecture open to the public.

HET Seminar | Nima Lashkari, MIT | “Universality of Quantum Information in Chaotic CFTs”

Fri, Dec 15, 2017, 1:45 pm

We study the Eigenstate Thermalization Hypothesis (ETH) in chaotic conformal field theories (CFTs) of arbitrary dimensions. Assuming local ETH, we compute the reduced density matrix of a ball-shaped subsystem of finite size in the infinite volume limit when the full system is an energy eigenstate.


Gravity Group Lunch Seminar, Kevin Crowley (Princeton University), "Transition-Edge Sensors for CMB Polarimetry"

Fri, Dec 15, 2017, 12:00 pm

Studies of the anisotropies in the Cosmic Microwave Background (CMB) are now focused on recovering primordial signals from polarization patterns on the sky. The demand for instruments with greater raw sensitivity is being met by scaling the density of telescope focal planes up to thousands, and tens of thousands, of detectors.

Hamilton Colloquium Series: Eric Siggia, Rockefeller University, “Exploring embryonic patterning with colonies of human embryonic stem cells”

Thu, Dec 14, 2017, 4:00 pm

Embryology at the beginning of the 21st century finds itself in a situation similar to neurobiology; the behavior of the component pieces is understood in some detail, but how they self-assemble to become life is still very hazy.

Audience: A free lecture open to the public.

Dicke Candidate Seminar | Claudio Savarese | "A Novel Light Detector for DarkSide-20K" | Jadwin A09

Wed, Dec 13, 2017, 2:30 pm

Abstract:  The DarkSide collaboration aims for a dark matter direct detection using Argon-based dual-phase Time
Projection Chambers (TPCs), capable of observing both the scintillation and the ionization signals of
recoiling nuclei. The DarkSide “zero-background” strategy exploits the pulse shape discrimination


HET Seminar at IAS | Kurt Hinterbichler, Case Western Reserve University | "TBA"

Mon, Dec 11, 2017, 2:30 pm

Dicke Candidate Seminar | Ariel Cukierman| Multiscale multichroic focal planes for measurements of the cosmic microwave background | Jadwin A09

Condensed Matter Seminar | Karol Gregor, Google DeepMind, London | "Machine Learning: Methods and recent successes." | PCTS, Seminar Room 407

Mon, Dec 11, 2017, 1:15 pm

Abstract:  Artificial Intelligence/Machine learning has seen large growth and a number of successes over the past few years. In this talk I will describe some of the core ideas and algorithms along with corresponding results. We will start by thinking about intelligence in general.


Hamilton Colloquium Series: Tilman Pfau, Universität Stuttgart, "Dipolar quantum gases and liquids"

Thu, Dec 7, 2017, 4:00 pm

Dipolar interactions are fundamentally different from the usual van der Waals forces in real gases. Besides the anisotropy the dipolar interaction is nonlocal and as such allows for self organized structure formation. Candidates for dipolar species are polar molecules, Rydberg atoms and magnetic atoms.

Audience: A free lecture open to the public.

HET Seminar | Alexander Zhiboedov, Harvard | “Conformal Field Theories in the Regge Limit” | PCTS Seminar Room

Mon, Dec 4, 2017, 2:30 pm

I will review recent developments in the understanding of Lorentzian correlators in generic CFTs. I will then discuss two applications of these developments. The first one involves bounds on the OPE coefficients on the leading Regge trajectory. In theories with gravity duals, it constrains certain higher-derivative corrections to the Einstein ...

HET Seminar | Zohar Komargodski, Stony Brook | "Dynamics in 2+1 Dimensions" | PCTS Seminar Room

Fri, Dec 1, 2017, 1:45 pm

We explain recent ideas that led to rapid progress on the dynamics of gauge theories in 2+1 dimensions. 

We discuss gauge theories with matter particles in the fundamental as well as in the adjoint representations. We make predictions for new phases of these theories and explain some special cases where these predictions can be already...


Gravity Group Lunch Seminar, Anne Gambrel (Princeton University), "SPIDER: First Flight Overview and Latest Analysis Results"

Fri, Dec 1, 2017, 12:00 pm

SPIDER is a balloon-borne telescope designed to measure the polarization of the cosmic microwave background at degree angular scales. With two flights, SPIDER aims to constrain the amplitude of primordial gravitational waves by measuring or placing an upper limit on the tensor-to-scalar ratio, r<0.03 (3 sigma) in the presence of foregrounds...
