• Abstract: In this short Topical Review, we look at something typically considered trivial, but not given formally elsewhere -- the behaviour of first multiple fermions, then multiple bosons, at a beamsplitter. Extending from this, we then describe the behaviour of multiple fermions and multiple bosons in Mach-Zehnder interferometers (MZIs). We hope that by showing how to go from mathematically-simple but unintuitive quantum field theory to a phenomenological description, this Review will help both researchers and students build a stronger intuition for the behaviour of quantum particles.

  Quantum correlations between distant particles remain enigmatic since the birth of quantum mechanics. We predict a novel kind of bound quantum state in the simplest one-dimensional setup of two interacting particles in a box. Such states could be realized in the waveguide quantum electrodynamics platform.

  We study the resolved R'enyi entropies of quasi-particle excited states in quantum field theory. We compute the ratio of charged moments of the partially transposed reduced density matrix as an expectation value of twist operators. We find that although the operation of partial transposition requires a redefinition for fermionic theories, the ratio of the negativity moments between an excited state and the ground state is universal and identical for fermions and bosons.

  We solve the problem of two fermion pairs numerically using the so-called ''coboson formalism'' This allows us to explore the strongly bound regime, approaching the limit of infinite attraction in which the composite particles behave as hard-core bosons.

• Duality between weak and strong interactions in quantum gases [0.0]
  No exact duality connecting strongly interacting bosons to weakly interacting fermions is known. Our derivation relies on regularizing the only point-like interaction between fermions in 1D. This allows one to apply standard methods of diagrammatic theory to strongly interacting bosons.

  Quantum simulation of lattice gauge theories (LGTs) aims at tackling non-perturbative particle and condensed matter physics. One of the current challenges is to go beyond 1+1 dimensions, where four-body (plaquette) interactions, not contained naturally in quantum simulating devices, appear. We show how to prepare the ground state and measure Wilson loops using state-of-the-art techniques in atomic physics.

  We will consider quantum field theory models relevant for particle physics and replace the fermionic matter in these models by a bosonic one. This is motivated by the fact that bosons are more accessible'' and easier to manipulate for experimentalists, but this substitution'' also leads to new physics and novel phenomena.

  We propose an analog simulator for discrete 2D quantum chemistry models based on cold atoms in optical lattices. We first analyze how to simulate simple models, like the discrete versions of H and H$+$, using a single fermionic atom. We then show that a single bosonic atom can mediate an effective Coulomb repulsion between two fermions, leading to the analog of molecular Hydrogen in two dimensions.
