Biophysics Seminar Series - Richard Neher (Max Planck Institute)
Recombination in intra-patient evolution of HIV
Joseph Henry Room · 12:00 p.m.– 1:00 p.m.
Condensed Matter Seminar, Garnet Chan, Numerical approaches to correlated electrons"
I will describe current research in our group to develop numerical methods for correlated electrons in systems of interest to chemistry and physics. I will survey a wide variety of techniques studied in our research, some of which are unique to our group, including: DMRG and tensor networks, dynamical mean-field theory and density matrix embedding, coupled cluster theory, and variational Monte Carlo. I will draw examples from applications to problems ranging from realistic chemical systems, such as active sites in biological enzymes, to problems of frustrated magnetism and the phase diagram of the Hubbard model. My hope is that as a new member of the Princeton community, this talk will provide an avenue to open up scholarly discussion and collaboration.
PCTS Seminar Room · 1:15 p.m.– 2:45 p.m.
High Energy Theory Seminar - IAS - Carlo Rovelli, Aix-Marseille University, France - Loop quantum Gravity: Recent Results and Open Problems
Description: The loop approach to quantum gravity has developed considerably during thelast few years, especially in its covariant ('spinfoam') version. Ipresent thecurrent definition of the theory and the results that have beenproven. I discusswhat I think is still missing towards of the goal of defining aconsistent tentativequantum field theory genuinely background independent and having generalrelativity as classical limit.
Bloomberg Lecture Hall · 2:30 p.m.– 3:30 p.m.

Condensed Matter Seminar, Karyn Le Hur, " Many-Bodied Quantum Physics with Photons"
In this Talk, we survey recent theoretical studies concerning the realization of many-body quantum physics with photons. First we introduce the Jaynes-Cummings lattice model and discuss the emergent Mott-Superfluid transition of light in electromagnetic resonator arrays which are under experimental investigation at Princeton in the group of Andrew Houck. Then, we show how to engineer artificial gauge fields for light and discuss related topological phases of photons in circuit QED systems. At a general level, transmission lines (long waveguides or Josephson junction arrays) can also be viewed as Ohmic dissipative baths that can also be used to engineer novel many-body physics with light. As an example, we discuss a way to emulate the spin-boson model or anisotropic Kondo model and we introduce the notion of photonic Kondo resonance obtained by sending microwave light in the underdamped limit.

Informal High Energy Theory Seminar - IAS - Alessandro Strumia, University of Pisa - “Unificaxion”
Bloomberg Lecture Hall · 1:30 p.m.– 2:30 p.m.
PHY-MAT-ASTRO Joint Open House
April 20th and 27th, 3:30-5pm

Colloquium: Energy: Technology, Economics, Policy, Informatics - Steve Koonin - Institute for Defense Analysis
National and global energy challenges involve security, competitiveness, and reduction in environmental impacts. Yet structural factors in energy systems retard the pace of energy change. I will discuss the technology, policy, and economic levers that can be used to accelerate the pact of energy transformation

Gravity Group Astrophysics/Cosmology Lunch
Joseph Henry Room · 12:00 p.m.– 1:30 p.m.
Condensed Matter Seminar, Leo Kouwenhoven, " Majorana Fermions in Semiconductor Nanowires"
Majorana fermions can arise as emergent particles in specially designed nanoscale conductors. We have combined superconductors and semiconducting nanowires with strong spin-orbit interaction. At finite magnetic field we find peaks in the density-of-states at zero-bias. The properties of this zero-bias peak compare well with the predictions for Majorana bound states.
