From New States of Matter to a Unification of Light and Electrons(Yukawa International Seminar 2004 (YKIS2004) Physics of Strongly Correlated Electron Systems) [PDF]
For a long time, people believe that all possible states of matter are described by Landau symmetry-breaking theory. Recently we found that string-net condensation provide a mechanism to produce states of matter beyond the symmetry-breaking description ...

Nano-pattern–induced ferromagnetism in strongly correlated electrons [PDF]
Band ferromagnetism in strongly correlated electron systems is one of the most challenging issues in today's condensed-matter physics. In this theoretical work, we study the competition between kinetic term, Coulomb repulsion, and on-site correlated ...

Kinks in the dispersion of strongly correlated electrons [PDF]
The properties of condensed matter are determined by single-particle and collective excitations and their mutual interactions. These quantum-mechanical excitations are characterized by an energy, E, and a momentum, ℏk, which are related through their ...

Theory of the density fluctuation spectrum of strongly correlated electrons. [PDF]
The density response function {ital N}({bold q},{omega}) of the two-dimensional {ital t}-{ital J} model is studied starting from a mixed- gauge formulation of the slave-boson approach.

A Quantum Gas Microscope for Detecting Single Atoms in a Hubbard-Regime Optical Lattice [PDF]
Recent years have seen tremendous progress in creating complex atomic many-body quantum systems. One approach is to use macroscopic, effectively thermodynamic ensembles of ultracold atoms to create quantum gases and strongly correlated states of matter ...

Exact result on the Mott transition in a two-dimensional model of strongly correlated electrons. [PDF]
We study the properties of a quarter-filled system of electrons on a square lattice interacting through a local repulsion $U$ and a nearest-neighbour repulsion $V$ in the limit $V=+\infty$.

Nonequilibrium electron spectroscopy of Luttinger liquids
Understanding the effects of nonequilibrium on strongly interacting quantum systems is a challenging problem in condensed matter physics. In dimensions greater than one, interacting electrons can often be understood within Fermi-liquid theory where low ...

Hierarchic Models of Turbulence, Superfluidity and Superconductivity [PDF]
New models of Turbulence, Superfluidity and Superconductivity, based on new Hierarchic theory, general for liquids and solids (physics/0102086), have been proposed. CONTENTS: 1 Turbulence.

Topological Mechanism of Superconductivity [PDF]
We outline the basic ideas of the topological mechanisms of superconductivity. A gauged model of correlated electronic system where a topological fluid is formed as a result of a strong interaction is discussed.

Large and Small Fermi-Surface Spin Density Waves in the Kondo Lattice Model [PDF]
We demonstrate the existence of metallic spin density waves (SDWs) in the Kondo lattice model on a square lattice for a wide range of parameters by means of real space dynamical mean field theory.
