1. Collective Effects When Photons Interact with Many Atoms

   Online Presentations | 30 Nov 2023 | Contributor(s):: Francis Robicheaux

2. Exploring Synthetic Quantum Materials in Superconducting Circuits

   Online Presentations | 30 Apr 2020

   Superconducting circuits have emerged as a competitive platform for quantum computation, satisfying the challenges of controllability, long coherence and strong interactions. I will show our recent experiments to apply this toolbox to the exploration of strongly correlated quantum materials made...

3. Many-body Expedition from Semiconductors to Atomic BECs

   Online Presentations | 11 Dec 2019 | Contributor(s):: Mackillo Kira

   Specifically, I will overview how methods of semiconductor quantum optics relate to phenomena in strongly interacting Bose gas. This expedition focuses on the first unitary BEC experiment which demonstrated that a surprisingly large BEC fraction survived a quench from weak to unitary...

4. Universal Variational Quantum Computation

   Online Presentations | 28 Oct 2019 | Contributor(s):: Jacob Biamonte

   We show that the variational approach to quantum enhanced algorithms admits a universal model of quantum computation.

5. Manipulating Strongly Interacting Individual Quanta: Photon Molecules and 51 Atomic Qubits

   Online Presentations | 26 Mar 2019 | Contributor(s):: Vladan Vuletic

   I will discuss two applications: By coherently coupling light to Rydberg excitations in a dense atomic medium, we have realized a highly nonlinear optical medium where the interactions between individual photons are so strong that two photons can even form a bound state.

6. Many Body Effects on Optical Properties of Graphene

   Online Presentations | 13 Oct 2016 | Contributor(s):: Subhasis Ghosh

   Graphene, a two-­dimensional (2D) material shows remarkable optical and electronic properties, such as a linear energy dispersion, chirality and half-­integer quantum Hall effect. Multilayer graphene flakes, held together by weak van der Waals forces have also attracted attention due to...

8. Lecture 4: The ab-initio Wigner Monte Carlo Method

   Online Presentations | 18 Nov 2014 | Contributor(s):: Jean Michel D Sellier

   In this lecture, Dr. Sellier discusses the ab-initio Wigner Monte Carlo method for the simulation of strongly correlated systems.
