Kinks in the dispersion of strongly correlated electrons [PDF]

, 2006
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 ...

Strange metals and the AdS/CFT correspondence [PDF]

, 2010
I begin with a review of quantum impurity models in condensed matter physics, in which a localized spin degree of freedom is coupled to an interacting conformal field theory in d = 2 spatial dimensions.

Nonequilibrium electron spectroscopy of Luttinger liquids

, 2009
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 ...

Exact result on the Mott transition in a two-dimensional model of strongly correlated electrons. [PDF]

Physical Review B (Condensed Matter), 1994
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 $V=+\infty$.

Oxide Heterostructures from a Realistic Many-Body Perspective

, 2018
Oxide heterostructures are a new class of materials by design, that open the possibility for engineering challenging electronic properties, in particular correlation effects beyond an effective single-particle description.

Electronic correlation effects in the Cr2GeC Mn+1AXn phase

, 2012
The magnetic properties, electronic band structure and Fermi surfaces of the hexagonal Cr2GeC system have been studied by means of both generalized gradient approximation (GGA) and the +U corrected method (GGA+U).

Interaction of a magnetic impurity with strongly correlated conduction electrons. [PDF]

Physical Review B (Condensed Matter), 1994
We consider a magnetic impurity which interacts by hybridization with a system of strongly correlated conduction electrons. The latter are described by a Hubbard Hamiltonian.

Method of computation of energies in the fractional quantum Hall effect regime [PDF]

, 2016
In a previous work, we reported exact results of energies of the ground state in the fractional quantum Hall effect (FQHE) regime for systems with up to $N_{\text{e}} = 6$ electrons at the filling factor $\nu = 1/3$ by using the method of complex polar ...

Discovering correlated fermions using quantum Monte Carlo

, 2016
It has become increasingly feasible to use quantum Monte Carlo (QMC) methods to study correlated fermion systems for realistic Hamiltonians. We give a summary of these techniques targeted at researchers in the field of correlated electrons, focusing on ...

Disentangling lattice and electronic contributions to the metal–insulator transition from bulk vs. layer confined RNiO₃

, 2019
In complex oxide materials, changes in electronic properties are often associated with changes in crystal structure, raising the question of the relative roles of the electronic and lattice effects in driving the metal–insulator transition.
