Quantum-Critical, Spin-Fluctuation-driven Residual Resistivity and Emergent Universal Correlations in the Fermi-Liquid Regime of Heavy-Fermion Superconductors
M. ElMassalami, P. B. Castro, M. B. Silva Neto
We investigate correlations within the unconventional Fermi-liquid (FL) regime of quantum-critical (QC) heavy-fermion superconductors (HFSs) by tracking the pressure dependence of…
Controlling spontaneous emission in inertial and dissipative nematic liquid crystals: the role of critical phenomena
J. H. Nascimento, F. A. Pinheiro, M. B. Silva Neto
We develop a rigorous, field-theoretical approach to the study of spontaneous emission in inertial and dissipative nematic liquid crystals, disclosing an alternative application of…
Controlling spontaneous emission via electronic correlations in transparent metals
M. B. Silva Neto, F. A. Pinheiro
We study the spontaneous emission of agglomerates of two-level quantum emitters embedded in a correlated transparent metal. The characteristic emission energy corresponds to the sp…
Characterizing critical exponents via Purcell effect
M. B. Silva-Neto, D. Szilard, F. S. S. Rosa +2
We investigate the role of phase transitions into the spontaneous emission rate of quantum emitters embedded in a critical medium. Using a Landau-Ginzburg approach, we find that, i…
Magnetic quantum phase transitions of the antiferromagnetic J_{1}-J_{2} Heisenberg model
T. P. Cysne, M. B. Silva Neto
We obtain the complete phase diagram of the antiferromagnetic - model, , within the framework of the nonlinear sigma model. We find two…
Skyrmions in a Doped Antiferromagnet
I. Raicevic, Dragana Popovic, C. Panagopoulos +4
Magnetization and magnetoresistance have been measured in insulating antiferromagnetic La_{2}Cu_{0.97}Li_{0.03}O_{4} over a wide range of temperatures, magnetic fields, and field o…
