Surface Charge Induced Dirac Band Splitting in a Charge Density Wave Material (TaSe4)2I
Hemian Yi, Zengle Huang, Wujun Shi +14
(TaSe4)2I, a quasi-one-dimensional (1D) crystal, shows a characteristic temperature-driven metal-insulator phase transition. Above the charge density wave (CDW) temperature Tc, (Ta…
Probing the pathway of an ultrafast structural phase transition to illuminate the transition mechanism in Cu2S
Junjie Li, Kai Sun, Jun Li +17
Disentangling the primary order parameter from secondary order parameters in phase transitions is critical to the interpretation of the transition mechanisms in strongly correlated…
Observation of Spontaneous Ferromagnetism in a Two-Dimensional Electron System
Md. S. Hossain, M. K. Ma, K. A. Villegas Rosales +5
What are the ground states of an interacting, low-density electron system? In the absence of disorder, it has long been expected that as the electron density is lowered, the exchan…
Visualizing Quasiparticles from Quantum Entanglement for general 1D phases
Elisabeth Wybo, Frank Pollmann, S. L. Sondhi +1
In this work, we present a quantum information framework for the entanglement behavior of the low energy quasiparticle (QP) excitations in various quantum phases in one-dimensional…
Structure, Magnetism and First Principles Modeling of the Na0.5La0.5RuO3 Perovskite
Loi T. Nguyen, Matthieu Saubanère, Robert J. Cava
High purity polycrystalline Na0.5La0.5RuO3 was synthesized by a solid state method, and its properties were studied by magnetic susceptibility, heat capacity and resistivity measur…
Bloch Ferromagnetism of Composite Fermions
Md. Shafayat Hossain, Tongzhou Zhao, Songyang Pu +9
In 1929 Felix Bloch suggested that the paramagnetic Fermi sea of electrons should make a spontaneous transition to a fully-magnetized state at very low densities, because the excha…
