We review two important non-perturbative approaches for extracting the physics of low-
dimensional strongly correlated quantum systems. Firstly, we start by providing a …

Spontaneous symmetry breaking is a general principle that constitutes the underlying
concept of a vast number of physical phenomena ranging from ferromagnetism and …

Quantum computers, though not yet available on the market, will revolutionize the future of
information processing. Quantum computers for special purposes like quantum simulators …

We review recent experimental and theoretical progress on ultracold alkaline-earth Fermi
gases with emergent SU (N) symmetry. Emphasis is placed on describing the ground …

We report on the creation of a degenerate Fermi gas consisting of a balanced mixture of
atoms in three different hyperfine states of Li 6. This new system consists of three …

Few-body physics has played a prominent role in atomic, molecular and nuclear physics
since the early days of quantum mechanics. It is now possible—thanks to tremendous …

We investigate the stability of a three spin state mixture of ultracold fermionic Li 6 atoms over
a range of magnetic fields encompassing three Feshbach resonances. For most field values …

We study fermionic atoms of three different internal quantum states (colors) in an optical
lattice, which are interacting through attractive on site interactions, U< 0. Using a variational …

Using quantum Monte Carlo simulations, we study a series of models of fermions coupled to
quantum Ising spins on a square lattice with N flavors of fermions per site for N= 1, 2, and 3 …

To begin with, we introduce several exact models for SU (3) spin chains: First is a
translationally invariant parent Hamiltonian involving four-site interactions for the trimer …
