Kondo Destruction and Quantum Criticality in Kondo Lattice Systems
Qimiao Si, J. H. Pixley, Emilian Nica +4
Considerable efforts have been made in recent years to theoretically understand quantum phase transitions in Kondo lattice systems. A particular focus is on Kondo destruction, whic…
Density Matrix Embedding from Broken Symmetry Lattice Mean-Fields
Ireneusz W. Bulik, Gustavo E. Scuseria, Jorge Dukelsky
Several variants of the recently proposed Density Matrix Embedding Theory (DMET) [G. Knizia and G. K-L. Chan, Phys. Rev. Lett. 109, 186404 (2012)] are formulated and tested. We sho…
Evidence for a Kondo destroying quantum critical point in YbRh2Si2
Frank Steglich, Heike Pfau, Stefan Lausberg +10
The heavy-fermion metal YbRhSi is a weak antiferromagnet below K. Application of a low magnetic field T () is sufficient to conti…
Strongly Correlated Materials
Emilia Morosan, Douglas Natelson, Andriy H. Nevidomskyy +1
Strongly correlated materials are profoundly affected by the repulsive electron-electron interaction. This stands in contrast to many commonly used materials such as silicon and al…
Multi-component symmetry-projected approach for molecular ground state correlations
Carlos A. Jiménez-Hoyos, R. Rodríguez-Guzmán, Gustavo E. Scuseria
The symmetry-projected Hartree--Fock ansatz for the electronic structure problem can efficiently account for static correlation in molecules, yet it is often unable to describe dyn…
Topological defects of Néel order and Kondo singlet formation for Kondo-Heisenberg model on a honeycomb lattice
Pallab Goswami, Qimiao Si
Heavy fermion systems represent a prototypical setting to study magnetic quantum phase transitions. A particular focus has been on the physics of Kondo destruction, which captures…
Quantum Phases of the Shastry-Sutherland Kondo Lattice: Implications for the Global Phase Diagram of Heavy Fermion Metals
J. H. Pixley, Rong Yu, Qimiao Si
Considerable recent theoretical and experimental efforts have been devoted to the study of quantum criticality and novel phases of antiferromagnetic heavy-fermion metals. In partic…
Doping influence of spin dynamics and magnetoelectric effect in hexagonal YLuMnO
W. Tian, Guotai Tan, Liu Liu +6
We use inelastic neutron scattering to study spin waves and their correlation with the magnetoelectric effect in YLuMnO. In the undoped YMnO and LuMnO,…
Pairing Correlations Near a Kondo-Destruction Quantum Critical Point
J. H. Pixley, Lili Deng, Kevin Ingersent +1
Motivated by the unconventional superconductivity observed in heavy-fermion metals, we investigate pairing susceptibilities near a continuous quantum phase transition of the Kondo-…
Multiple quantum phase transitions in a heavy fermion antiferromagnet
L. Jiao, H. Q. Yuan, Y. Kohama +12
We report measurements of magnetic quantum oscillations and specific heat at low temperatures across a field-induced antiferromagnetic quantum critical point (QCP)(B_{c0}\approx50T…
Quantum critical Kondo destruction in the Bose-Fermi Kondo model with a local transverse field
Emilian Marius Nica, Kevin Ingersent, Jian-Xin Zhu +1
Recent studies of the global phase diagram of quantum-critical heavy-fermion metals prompt consideration of the interplay between the Kondo interactions and quantum fluctuations of…
Thermal and Electrical Transport across a Magnetic Quantum Critical Point
H. Pfau, S. Hartmann, U. Stockert +11
A quantum critical point (QCP) arises at a continuous transition between competing phases at zero temperature. Collective excitations at magnetic QCPs give rise to metallic propert…
Quantum criticality in the pseudogap Bose-Fermi Anderson and Kondo models: Interplay between fermion- and boson-induced Kondo destruction
J. H. Pixley, Stefan Kirchner, Kevin Ingersent +1
We address the phenomenon of critical Kondo destruction in pseudogap Bose-Fermi Anderson and Kondo quantum impurity models. These models describe a localized level coupled both to…
Multi-reference symmetry-projected variational approaches for ground and excited states of the one-dimensional Hubbard model
R. Rodríguez-Guzmán, Carlos A. Jiménez-Hoyos, R. Schutski +1
We present a multi-reference configuration mixing scheme for describing ground and excited states, with well defined spin and space group symmetry quantum numbers, of the one-dimen…
Quantum phase transitions in heavy fermion metals and Kondo insulators
Qimiao Si, Silke Paschen
Strongly correlated electron systems at the border of magnetism are of active current interest, particularly because the accompanying quantum criticality provides a route towards b…
Local quantum criticality out of equilibrium - effective temperatures and scaling in the steady state regime
Pedro Ribeiro, Qimiao Si, Stefan Kirchner
We study the out of equilibrium steady state properties of the Bose-Fermi-Kondo model, describing a local magnetic moment coupled to two ferromagnetic leads that support bosonic (m…

Liang L. Zhao, Shan Wu, Jiakui K. Wang +3
The magnetism of SrFFeOS was examined through neutron powder diffraction and thermodynamic and transport measurements. Quasi-two-dimensional magnetic order develops…
Transport Characterization of Kondo-Correlated Single Molecule Devices
Gavin D. Scott, Douglas Natelson, Stefan Kirchner +1
A single molecule break junction device serves as a tunable model system for probing the many body Kondo state. The low-energy properties of this state are commonly described in te…
