Many-body Quantum Dynamics

Cavendish Laboratory

Welcome to our website!

We are studying many-body phenomena at the interface between quantum optics and solid state physics. Following a statement by P.W. Anderson, "More is Different", genuine many-body phenomena are emergent phenomena that only appear when many particles come together, typical examples being superfluidity or magnetism.

Our main tool are quantum gases and in particular ultracold atoms in optical lattices.

  • One avenue of research is the creation and analysis of novel synthetic quantum matter, that is novel many-body systems with fascinating properties, for instance novel types of order. Examples include topological systems or many-body localisation.
  • Another direction is quantum simulation. Here we aim to study existing problems such as the physics of strongly-correlated materials, which are in general impossible to model using classical supercomputers. The main workhorse here is the implementation of bosonic and fermionic Hubbard models in our experiments.
  • In particular, we are often interested in the non-equilibrium dynamics of the above systems.

Hubbard Models for Quasicrystalline Potentials

13 October 2022

Our latest work on creating Hubbard Models for Quasicrystalline Potentials is now on the Arxiv (2210.05691). In it, we present a numerical method for constructing the Hubbard Hamiltonian of non-periodic potentials without making use of Bloch's theorem, and then apply it to the eightfold rotationally symmetric 2D optical...

Towards quantum simulation of false vacuum decay

20 January 2022

In our lastest work we have used a resonantly driven optical lattice to turn the Mott transition into a first-order (discontinuous) transition. We were able to directly observe the associated hysteresis and metastability, where the system remains stuck in its original phase (the false vacuum) even though the ground state...

First AION collaboration workshop

11 November 2021

Finally, we were able to hold teh first in-person collaboration of the new AION collaboration, where we want to develop large scale atom interferometers. aion_collaboration_nov21_2mp.jpg
