Mott Insulators, Spin Liquids and Quantum Disordered Superconductivity
نویسنده
چکیده
These introductory lecture notes describe recent results on novel Mott insulating phases which are “descendents” of superconductors – obtained by “quantum disordering”. After a brief overview of quantum magnetism, attention is focussed on the spin – liquid phase of the two-leg Hubbard ladder and the nodal liquid – a descendent of the dx2−y2 superconductor. These notes are self-contained and an effort has been made to keep them accessible.

Prospect of quantum anomalous Hall and quantum spin Hall effect in doped kagome lattice Mott insulators
Electronic states with non-trivial topology host a number of novel phenomena with potential for revolutionizing information technology. The quantum anomalous Hall effect provides spin-polarized dissipation-free transport of electrons, while the quantum spin Hall effect in combination with superconductivity has been proposed as the basis for realizing decoherence-free quantum computing. We intro...
متن کاملDesigning Quantum Spin-Orbital Liquids in Artificial Mott Insulators
Quantum spin-orbital liquids are elusive strongly correlated states of matter that emerge from quantum frustration between spin and orbital degrees of freedom. A promising route towards the observation of those states is the creation of artificial Mott insulators where antiferromagnetic correlations between spins and orbitals can be designed. We show that Coulomb impurity lattices on the surfac...
متن کامل0 Topological Aspects of Spin Pairing in High - T c Superconductivity and Berry Phase
From topological viewpoint we have analysed the role of Berry phase in spin pairing mechanism of high T c superconducting ground state. Difficulty of achieving a high transition temperature for the high temperature super-conductors which are doped Mott insulators via the conventional mechanism leads to a different approach towards pairing. Any theory of high temperature superconductivity should...
متن کاملQuantum spin liquids
This paper presents an overview of the properties of magnetic insulators, with emphasis on quantum effects. In particular, the consequences of strong quantum fluctuations on the low-energy properties of a number of systems are reviewed: the occurrence of a spin gap in spin-1 chains and other low-dimensional magnets; the presence of low-lying singlet excitations in several frustrated magnets; th...
