Collective Excitations in the Charge-Ordered Phase of alpha-(BEDT-TTF)2I3
T. Ivek, B. Korin-Hamzic, O. Milat +5
The charge response of charge-ordered state in the organic conductor alpha-(BEDT-TTF)2I3 is characterized by dc resistivity, dielectric and optical spectroscopy in different crysta…
Antiferromagnetism of Repulsively Interacting Fermions in a harmonic trap
Jianqing Qi, Lei Wang, Xi Dai
We propose a Real-Space Gutzwiller variational approach and apply it to a system of repulsively interacting ultracold fermions with spin 1/2 trapped in an optical lattice with a ha…
Infrared anomalous Hall effect in SrRuO: Evidence for crossover to intrinsic behavior
M. -H. Kim, G. Acbas, M. -H. Yang +7
The origin of the Hall effect in many itinerant ferromagnets is still not resolved, with an anomalous contribution from the sample magnetization that can exhibit extrinsic or intri…
Continuous metal-insulator transition of the antiferromagnetic perovskite NaOsO3
Y. G. Shi, Y. F. Guo, S. Yu +11
Newly synthesized perovskite NaOsO3 shows Curie-Weiss metallic nature at high temperature and suddenly goes into an antiferromagnetically insulating state at 410 K on cooling. Elec…
Spin and charge order in doped Hubbard model: long-wavelength collective modes
Chia-Chen Chang, Shiwei Zhang
Determining the ground state properties of the two-dimensional Hubbard model has remained an outstanding problem. Applying recent advances in constrained path auxiliary-field quant…
Cooperative order and excitation spectra in the bicomponent spin networks
Bao Xu, Han-Ting Wang, Yupeng Wang
A ferrimagnetic spin model composed of spin-dimers and spin-chains is studied by combining the bond-operator representation (for spin-dimers) and Holstein-P…
