Recent advances in materials fabrication have enabled the manufacturing of ordered 2D
electron systems, such as heterogeneous interfaces, atomic layers grown by molecular …

With the high-temperature superconductors a qualitatively new regime in the
phenomenology of type-II superconductivity can be accessed. The key elements governing …

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

Observation of strong correlations and superconductivity in twisted-bilayer graphene,,–has
stimulated tremendous interest in fundamental and applied physics,,–. In this system, the …

The dynamics of an ultracold dilute gas of bosonic atoms in an optical lattice can be
described by a Bose-Hubbard model where the system parameters are controlled by laser …

This paper reviews the recent theoretical and experimental advances in the study of ultra-
cold gases made of bosonic particles interacting via the long-range, anisotropic dipole …

These lecture notes introduce quantum spin systems and several computational methods for
studying their ground‐state and finite‐temperature properties. Symmetry‐breaking and …

One of Feynman's early applications of path integrals was to superfluid He 4. He showed
that the thermodynamic properties of Bose systems are exactly equivalent to those of a …

We review recent developments in the physics of ultracold atomic and molecular gases in
optical lattices. Such systems are nearly perfect realisations of various kinds of Hubbard …

A quantum system can undergo a continuous phase transition at the absolute zero of
temperature as some parameter entering its Hamiltonian is varied. These transitions are …
