Spin Dynamics of a J1-J2-K Model for the Paramagnetic Phase of Iron Pnictides
Rong Yu, Zhentao Wang, Pallab Goswami +3
We study the finite-temperature spin dynamics of the paramagnetic phase of iron pnictides within an antiferromagnetic J_1-J_2 Heisenberg model on a square lattice with a biquadrati…
Quantum criticality of the sub-ohmic spin-boson model
Stefan Kirchner, Kevin Ingersent, Qimiao Si
We revisit the critical behavior of the sub-ohmic spin-boson model. Analysis of both the leading and subleading terms in the temperature dependence of the inverse static local spin…
One-Dimensional Quantum Liquids: Beyond the Luttinger Liquid Paradigm
Adilet Imambekov, Thomas L. Schmidt, Leonid I. Glazman
For many years, the Luttinger liquid theory has served as a useful paradigm for the description of one-dimensional (1D) quantum fluids in the limit of low energies. This theory is…
Bose glass and Mott glass of quasiparticles in a doped quantum magnet
Rong Yu, Liang Yin, Neil S. Sullivan +12
The low-temperature states of bosonic fluids exhibit fundamental quantum effects at the macroscopic scale: the best-known examples are Bose-Einstein condensation (BEC) and superflu…
Kondo destruction and valence fluctuations in an Anderson model
J. H. Pixley, Stefan Kirchner, Kevin Ingersent +1
Unconventional quantum criticality in heavy-fermion systems has been extensively analyzed in terms of a critical destruction of the Kondo effect. Motivated by a recent demonstratio…
Sr3Ru2O7: Thermodynamics of Phase Formation in a Quantum Critical Metal
A. W. Rost, S. A. Grigera, J. A. N. Bruin +5
The behaviour of matter near zero temperature continuous phase transitions, or 'quantum critical points' (QCPs) is a central topic of study in condensed matter physics. In fermioni…
Thermal and electrical transport in the spin density wave antiferromagnet CaFeAs
M. S. Kim, Z. P. Yin, L. L. Zhao +3
We present here measurements of the thermopower, thermal conductivity, and electrical resistivity of the newly reported compound CaFe4As3. Evidence is presented from specific heat…
Projected Quasiparticle Theory for Molecular Electronic Structure
Gustavo E. Scuseria, Carlos A. Jimenez-Hoyos, Thomas M. Henderson +2
We derive and implement symmetry-projected Hartree-Fock-Bogoliubov (HFB) equations and apply them to the molecular electronic structure problem. All symmetries (particle number, sp…
Anomalous magneto-optical Kerr hysteresis loops in FeTaS
C. Sun, J. Kono, A. Imambekov +1
We have performed magneto-optical Kerr spectroscopy measurements on intercalated transition-metal dichalcogenide FeTaS in the polar Kerr geometry as a function of te…
Correlations in Quantum Spin Ladders with Site and Bond Dilution
Kien Trinh, Stephan Haas, Rong Yu +1
We investigate the effects of quenched disorder, in the form of site and bond dilution, on the physics of the antiferromagnetic Heisenberg model on even-leg ladders. Site d…
Heavy Fermions and Quantum Phase Transitions
Qimiao Si, Frank Steglich
Quantum phase transitions arise in many-body systems due to competing interactions that promote rivaling ground states. Recent years have seen the identification of continuous quan…
Quantum Criticality without Tuning in the Mixed Valence Compound beta-YbAlB4
Yosuke Matsumoto, Satoru Nakatsuji, Kentaro Kuga +6
Fermi liquid theory, the standard theory of metals, has been challenged by a number of observations of anomalous metallic behavior found in the vicinity of a quantum phase transiti…
