Unusual band evolution and persistence of topological surface states in high-T_C magnetic topological insulator
K. Hori, S. Souma, C. -W. Chuang +12
Understanding the mechanism of ferromagnetism in ferromagnetic topological insulators (TIs) is a key to realize exotic time-reversal-symmetry-broken quantum phases. However, electr…
Oxygen on-site Coulomb energy in PrLaCeCuO and BiSrCaCuO and its relation with Heisenberg exchange
A. Chainani, M. Horio, C. -M. Cheng +20
We study the electronic structure of electron-doped PrLaCeCuO (PLCCO ; = 27 K, x = 0.1) and hole-doped BiSrCaCuO (Bi2212 ;…
Connecting the one-band and three-band Hubbard models of cuprates via spectroscopy and scattering experiments
K. Sheshadri, D. Malterre, A. Fujimori +1
The one-band and three-band Hubbard models which describe the electronic structure of cuprates indicate very different values of effective electronic parameters, such as the on-sit…
Robust charge-density wave strengthened by electron correlations in monolayer 1T-TaSe2 and 1T-NbSe2
Yuki Nakata, Katsuaki Sugawara, Ashish Chainani +11
Combination of low-dimensionality and electron correlation is vital for exotic quantum phenomena such as the Mott-insulating phase and high-temperature superconductivity. Transitio…
Unconventional Superfluidity in a model of Fermi-Bose Mixtures
K. Sheshadri, A. Chainani
A finite-temperature () study of a model of a mixture of spin-zero hardcore bosons and spinless fermions, with filling fractions and , respectively, on a two-dimens…
Evolution of valence-specific spin states and local distortions in LaSrCoO
J. Okamoto, A. Chainani, Z. Y. Chen +7
We present X-ray spectroscopic evidence for the evolution of valence-specific spin states and tetragonal distortions in single-layer cobaltates. Measurements of Co -edge reson…
