We develop a self-consistent variant of the constrained path quantum Monte Carlo approach which ensures its independence of the trial wave function, and apply the method to compute …
We study the correlation clustering problem using the quantum approximate optimization algorithm (QAOA) and qudits, which constitute a natural platform for such non-binary …
The joint action of a magnetic field and of interactions is crucial for the appearance of exotic quantum phenomena, such as the quantum Hall effect. Owing to their rich nuclear structure …
We study the quantum phases of fermions with an explicit SU (N)-symmetric, Heisenberg- like nearest-neighbor flavor exchange interaction on the honeycomb lattice at half filling …

Quantum magnets with a large SU (N) symmetry are a promising playground for the discovery of new forms of exotic quantum matter. Motivated by recent experimental efforts to …
We explore the phase diagram of the SU (N) Hubbard models describing fermionic alkaline- earth-metal atoms in a square optical lattice with, on average, one atom per site, using a …

We explore the Dirac spin liquid (DSL) as a candidate for the ground state of the Mott insulating phase of fermions with six flavors on the kagome lattice, particularly focusing on …
We investigate a species selective cooling process of a trapped SU (N) Fermi gas using entropy redistribution during adiabatic loading of an optical lattice. Using high-temperature …
This thesis reports on the experimental realization of the 3D SU (N) Fermi-Hubbard model and the direct probing of the equation of state with an ultracold quantum gas of fermionic …
