A Quantum Gas Microscope for Detecting Single Atoms in a Hubbard-Regime Optical Lattice [PDF]

open access: yes, 2011
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 ...

Dynamical Mean-Field Theory

open access: yes, 2011
The dynamical mean-field theory (DMFT) is a widely applicable approximation scheme for the investigation of correlated quantum many-particle systems on a lattice, e.g., electrons in solids and cold atoms in optical lattices.

Strong Electronic Correlation Effects in Coherent Multidimensional Nonlinear Optical Spectroscopy [PDF]

open access: yes, 2011
We discuss a many−body theory of the coherent ultrafast nonlinear optical response of systems with a strongly correlated electronic ground state that responds unadiabatically to photoexcitation. We introduce a truncation of quantum kinetic density matrix

Emergent electromagnetism in condensed matter

open access: yesProceedings of the Japan Academy. Series B, Physical and biological sciences, 2019
Electrons in solids constitute quantum many-body systems showing a variety of phenomena. It often happens that the eigen states of the Hamiltonian are classified into subgroups separated by energy gaps.

Thirty Years of heavy Fermions: Scientific Setting for their Discovery and Partial Understanding

open access: yes, 2005
Heavy-Fermions provide an extreme example of the utility of the idea of continuity and analyticity in physics. Their discovery and study in the past thirty years has added a fascinating chapter to condensed matter physics. I briefly review the origins of

High Temperature Superconductivity: the explanation

open access: yes, 2011
Soon after the discovery of the first high temperature superconductor by Georg Bednorz and Alex Mueller in 1986 the late Sir Nevill Mott answering his own question "Is there an explanation?" [Nature v 327 (1987) 185] expressed a view that the Bose ...

What can gauge-gravity duality teach us about condensed matter physics? [PDF]

open access: yes, 2012
I discuss the impact of gauge-gravity duality on our understanding of two classes of systems: conformal quantum matter and compressible quantum matter.

Exploration and prediction of topological electronic materials based on first-principles calculations

open access: yes, 2014
The class of topological insulator materials is one of the frontier topics of condensed matter physics. The great success of this field is due to the conceptual breakthroughs in theories for topological electronic states and is strongly motivated by the ...

Pairing instabilities in topological insulator quantum wells

open access: yes, 2013
Topological insulator quantum wells with induced attractive interactions between electrons are candidate systems for the realization of novel vortex lattice states with time-reversal symmetry, and incompressible quantum vortex liquids with fractional ...

Strongly correlated flat-band systems: The route from Heisenberg spins to Hubbard electrons

open access: yes, 2015
In this review we recapitulate the basic features of the flat-band spin systems and briefly summarize earlier studies in the field. Main emphasis is made on recent developments which include results for both spin and electron flat-band models.
