 <p>It is important to take into account the effects of special relativity in the quantum description of chemical systems with heavy elements. The relativistic effects account for gold’s color, mercury’s liquid state at room temperature and are responsible for the efficiency of lead-acid batteries in cars [1]. Relativistic electronic-structure computational methods have been developed in the no-pair approximation, and are now routinely applied on molecular systems. Hence, the next challenge is to go beyond the no-pair approximation by including the quantum-electrodynamics (QED) effects of virtual electron-positron pairs. Such description is needed to recover some properties, even in very simple systems, e.g. the Lamb shift in the Hydrogen atom. In this work we are interested in a one-dimensional model of relativistic hydrogen-like atom using delta-potential interactions. It is motivated by the non-relativistic version of this model which leads to the same ground-state energy and radial wave function as the three-dimensional one [2]. In this model we are able to make accurate QED calculations [3]. After calculating the spectrum of the 1D Dirac operator [4]

 <p>Despite our very good understanding of several models in one dimension involving interacting (Dirac) fermions, the case of Majorana fermions has remained relatively unexplored. This is probably due to the fact that Majorana particles are not found as elementary objects in nature. Nevertheless, 20 years ago, in the context of modeling p-wave superconducting wires, Alexei Kitaev proposed a very influential yet simple toy model in which unpaired Majorana fermions can appear as edge states. In this talk I will present the basics of this problem and explore the non-trivial effects of interactions in such a system, building on DMRG and self-consistent mean-field approaches. If time permits, I may also touch on disorder effects&hellip;</p>

-<p><strong>Nuclear superfluidity: the Pairing Hamiltonian as a many-body testbed</strong></p>
+<p><a href="https://lcpq.github.io/MSQM/presentations/ATichai.pdf">Nuclear superfluidity: the Pairing Hamiltonian as a many-body testbed</a></p>
 <p>Atomic nuclei away from shell closures are characterized by strong static correlations that are (partly) linked to the emergence of superfluidity responsible for characteristic patterns in the nuclear phenomenology, e.g. odd-even mass staggering along isotopic chains. While the onset of superfluidity is accompanied by a breakdown of symmetry-conserving Hartree-Fock theory, the corresponding pairing correlations can be efficiently grasped by spontaneously breaking (and restoring) particle-number symmetry.</p>
 <p>In this talk I will discuss the Pairing Hamiltonian as a schematic model for superfluidity. Its exact solution for arbitrary system size is available from the seminal work of Richardson from the 1960s [1]. Since then it has been frequently used as a testbed in (nuclear) many-body theory.
 I will review a collection of frameworks including mean-field theory, many-body perturbation theory [2] and coupled cluster theory [3,4], and highlight the role of the symmetry restoration.

+<p><a href="https://lcpq.github.io/MSQM/presentations/AKirsch.pdf">Some mathematical insights on DMFT on a Hubbard model</a></p>
 <p>In this talk, I will discuss recent work on the mathematical properties of the Dynamical Mean-Field Theory applied to the Hubbard model [2, 4, 1]. In spite of its general use in condensed matter physics, the mathematical framework of DMFT has not been explored thoroughly: to our knowledge, this issue has only been addressed in [3], where it is shown that the self-consistent map is well defined for a particular set of functions representing a finite bath. In this talk, after a brief reminder on the Hubbard model and the DMFT formalism, I will present joint work with S. Perrin-Roussel and E. Cances in which we start by extending this result to a larger class of functions that can model infinite bath. I will also detail results on a specific impurity solver, the Iterated Perturbation Theory (IPT). If time allows, I will then discuss numerical developments arising from these results (using TRIQS [5]) and the well-posedness of the DMFT equations in this frame.</p>

 <p>In this talk, we consider a model consisting of differential equations coupling the time evolution of a finite number of relativistic electrons with the Newtonian dynamics of finitely many nuclei, where the former is described by the Bogoliubov-Dirac-Fock (BDF) equation of quantum electrodynamics (QED). The Cauchy problem for this model is addressed, proving a global well-posedness result. We believe that this system can be seen as a first step in the study of molecular dynamics phenomena, when both relativistic and quantum effects have to be taken into account [1].</p>

+<p><a href="https://lcpq.github.io/MSQM/presentations/LReining.pdf">Zero, one, many: the Hubbard dimer with two electrons in many-body perturbation theory</a></p>
 <p>Many-body perturbation theory is today part of the standard toolbox of first principles calculations. Most often, first-or at most second-order approximations are used. Still, calculations for real materials can be very involved. Moreover, numerous open questions remain, not least because for both total energies and spectra we do not have enough thorough benchmarks. This explains why, for example, after decades of GW calculations the best choice for the Green&rsquo;s function G and for the screened Coulomb interaction W to build the GW self-energy is still a matter of debate.</p>
 <p>One way to contribute to filling this gap is the use of simple solvable models. Here, we will examine results for the symmetric half-filled Hubbard dimer, which allows us to cover the full range from vanishing to strong correlation. Our aim is to design an optimal way to use MBPT, remaining at low order, with a particular focus on the design of effective interactions. This will include combinations of MBPT with time-dependent density functional theory.</p>
 <p>We will illustrate how the simple model allows us to benchmark, and also to understand and to improve results. Finally, we will also discuss limitations of the extrapolation of results from the Hubbard dimer to real systems.</p>

+<p><a href="https://lcpq.github.io/MSQM/presentations/DGontier.pdf">Phase transition in the Peierls / SSH model</a></p>
 <p>The Peierls/SSH model is a simple one-dimensional model used to describe molecular chains such as polyacetylene. In this model, we consider a distortion energy between the atoms, and an electronic quantum energy given by a tight-binding model. Peierls showed that it was energetically favorable for the chain to dimerize (hence the structure …=C-C=C-… of polyacetylene). In this talk, we will study the phase diagram of this model, when we add temperature. We show the existence of a critical temperature above which the chain no longer dimerizes.

 <p>In the first part of the talk we will consider a system of bosons with contact interaction in one dimension, the Lieb-Liniger model. Then, we will study the motion of a slow impurity (a foreign particle) through this system. While at zero temperature the impurity motion is frictionless, at low temperatures finite friction appears due to scattering off thermally excited quasiparticles. We will derive analytical results for the friction force within a microscopic theory and uncover interesting regimes of the impurity dynamics.</p>

 <p>In this presentation, I will present several simple systems that allow us to describe complex time-dependent processes. In particular I will show that low dimensional systems are powerful tools to model the strong-field driven dynamics of atoms and molecules. Indeed, these model systems allow to directly solve the Time-Dependent Schrödinger Equation and therefore accurately represent highly non-linear processes such as tunnel ionization or high-order harmonic generation.</p>
