An overview of one-and two-dimensional quantum spin systems based on transition-metal
oxides and halides of current interest is given, such as spin-Peierls, spin-dimer …

The discovery of magnetism by the ancient Greeks was enabled by the natural occurrence of
lodestone–a magnetized version of the mineral magnetite. Nowadays, natural minerals …

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 perform a density-matrix renormalization group (DMRG) study of the S= 1 2 Heisenberg
antiferromagnet on the kagome lattice to identify the conjectured spin liquid ground state …

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 …

The syntheses and magnetic susceptibilities of a pure series of rare copper minerals from
the atacamite family with general formula Zn x Cu4-x (OH) 6Cl2 (0≤ x≤ 1) are reported. The …

We present a comprehensive computational study of the phase diagram of the frustrated S=
1/2 Heisenberg antiferromagnet on the honeycomb lattice, with second-nearest (J 2) and …

Quantum electrodynamics in 2+ 1 dimensions (QED 3) has been proposed as a critical field
theory describing the low-energy effective theory of a putative algebraic Dirac spin liquid or …

We demonstrate the possibility of creating and controlling an ideal and trimerized optical
Kagomé lattice, and study the low temperature physics of various atomic gases in such …

Using both exact diagonalizations and diagonalizations in a subset of short-range valence-
bond singlets, we address the nature of the groundstate of the Heisenberg spin-1∕ 2 …
