With a self-contained presentation, it provides a broad overview of the rapidly evolving area of cold atoms and is of interest to both undergraduates and researchers working in the field. Starting with a general introduction to the physics of cold atoms and optical lattices, it extends the theory to that of systems with different multispecies atoms. It advances the theory of many-body quantum systems in excited bands (of optical lattices) through an extensive study of the properties of both the mean-field and strongly correlated regimes. Particular emphasis is given to the context of quantum simulation, where as shown here, the orbital degree of freedom in excited bands allows the study of exotic models of magnetism not easily achievable with the previous alternative systems. In addition, it proposes a new model Hamiltonian that serves as a quantum simulator of various disordered systems in different symmetry classes that can easily be reproduced experimentally. This is of great interest, especially for the study of disorder in 2D quantum systems. .Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Phase transformations (Statistical physics)Condensed materialsLow temperature physicsLow temperaturesQuantum computersSpintronicsQuantum physicsQuantum Gases and Condensateshttps://scigraph.springernature.com/ontologies/product-market-codes/P24033Low Temperature Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P25130Quantum Information Technology, Spintronicshttps://scigraph.springernature.com/ontologies/product-market-codes/P31070Quantum Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19080Phase transformations (Statistical physics).Condensed materials.Low temperature physics.Low temperatures.Quantum computers.Spintronics.Quantum physics.Quantum Gases and Condensates.Low Temperature Physics.Quantum Information Technology, Spintronics.Quantum Physics.621.36Pinheiro Fernandaauthttp://id.loc.gov/vocabulary/relators/aut805589MiAaPQMiAaPQMiAaPQBOOK9910254628903321Multi-species Systems in Optical Lattices2544875UNINA
