A DQMC study of the spectral and conductive properties of the two-dimensional Holstein model
J. Neuhaus, B. Cohen-Stead, N. Mannella +1
We study the dynamical properties of the two-dimensional square lattice Holstein Hamiltonian using numerically exact determinant quantum Monte Carlo simulations. In particular, we…
Controllable Strain-driven Topological Phase Transition and Dominant Surface State Transport in High-Quality HfTe5 Samples
Jinyu Liu, Yinong Zhou, Sebastian Yepez Rodriguez +11
Controlling materials to create and tune topological phases of matter could potentially be used to explore new phases of topological quantum matter and to create novel devices wher…
Disentangling Electronic, Lattice and Spin Dynamics in the Chiral Helimagnet Cr1/3NbS2
N. Sirica, H. Hedayat, D. Bugini +7
We investigate the static and ultrafast magneto-optical response of the hexagonal chiral helimagnet above and below the helimagnetic ordering temperature. The pre…
The nature of ferromagnetism in the chiral helimagnet
N. Sirica, P. Vilmercati, F. Bondino +12
The chiral helimagnet, , hosts exotic spin textures, whose influence on the magneto-transport properties, make this material an ideal candidate for future spintron…
Non-rigid band shift and non-monotonic electronic structure changes upon doping in the normal state of the pnictide high temperature superconductor Ba2(Fe1-xCox)2As2
PPaolo Vilmercati, Sung-Kwan Mo, Alexei Fedorov +8
We report systematic Angle Resolved Photoemission (ARPES) experiments using different photon polarizations and experimental geometries and find that the doping evolution of the nor…
Spectroscopic Evidence for Strong Quantum Spin Fluctuations with Itinerant Character in YFe2Ge2
N. Sirica, F. Bondino, S. Nappini +6
We report x-ray absorption and photoemission spectroscopy of the electronic structure in the normal state of metallic YFe2Ge2. The data reveal evidence for large fluctuating spin m…
