Hi !
I’m Ludovic, a CNRS researcher working in the Condensed Matter Theory group of the LOMA in Bordeaux. Before joining CNRS, I worked in Okinawa, Oxford, Dresden and Lyon.
We are interested in what happens when electrons are not happy to live together in a crystal. More precisely, in some materials, all interactions between spins cannot be satisfied at the same time. This leads to what is called magnetic frustration and strongly hinders the system to order on long length scales. In our everyday life, it would be the same as if a cup of water would never freeze, even in the middle of Antarctica !
For scientists, frustration has opened a window to explore some of the hidden properties of matter at very low temperatures, which is where quantum mechanics rules. We spend most of our time looking through this window, trying to make sense of what we see. The absence of order often leads to persistent fluctuations, paradoxically coupled to strong magnetic correlations. These phases, called « spin liquids », can often be described rather beautifully by emergent gauge field theories, making contact with a physics usually attached to high energy. In this field, we are especially interested in emergent phenomena (quasi-particles, extended fractal structures …), topological phases, exotic phase transitions and out-of-equilibrium dynamics, to cite but a few. Our research often sits at the frontier between Condensed Matter, Quantum and Statistical Physics.

Naïmo Davier – Postdoc
I am a postdoctoral researcher aiming to better understand theoretical physics, especially condensed matter systems. I am currently focusing on frustrated systems, which allow for the emergence of rich and unusual physics from seemingly simple systems. To study these systems, I use various analytical tools, such as mean-field approximations, coupled with Monte Carlo simulations, which provide an explicit glimpse into the system’s behavior and offer insights on the appropriate analytical approach to choose.

Kelvin Salou-Smith – PhD student
I did my Master at Sorbonne/ENS in the ICFP program where I studied theoretical condensed matter. I’m interested in spin systems and the complexity that can emmerge from seemingly simple models. Studying their ground states and excitations can become very difficult when dealing with large lattices and highly entangled states. To deal with this complexity, I’ll be approaching this problem with Neural Quantum States, a variational approach where the variational wave function is represented by a Neural-Network. Outside of work, I enjoy swimming, playing piano, and making cocktails.

Emile Lasserre – Master 2 student
I am a student at the University Bordeaux in the master Light Matter and iNteraction, and I am particularly interested in quantum mechanics and condensed matter theory. I aim to simulate the many-body physics of quantum materials. This can be very difficult as the Hilbert space of those systems grows exponentially with the number of particles. To overcome this issue, I use Tensor Networks, which are a very efficient tool to numerically simulate the behavior of a quantum state, while keeping the entanglement informations about it. It allows for small deviations to the exact solution.

Yosef Shokeeb – Master 1 student
I’m a Master student in the EURLight program at the Institut d’Optique Graduate School, currently working on AdS/CFT correspondence in hyperbolic lattices. In the past I have also worked on implementing deep learning to the analysis of anomalous Brownian diffusion. After my Master, I wish to pursue a PhD on Field Theories in the context of condensed matter physics. In my free time I enjoy juggling, long walks and discovering new restaurants!
