A pressure-induced topological phase with large Berry curvature in PbSnTe
Tian Liang, Satya Kushwaha, Jinwoong Kim +5
The picture of how a gap closes in a semiconductor has been radically transformed by topological concepts. Instead of the gap closing and immediately re-opening, topological argume…
Tuning the magnetism of ordered and disordered strongly-correlated electron nanoclusters
N. Kioussis, Y. Luo, C. Verdozzi
Recently, there has been a resurgence of intense experimental and theoretical interest on the Kondo physics of nanoscopic and mesoscopic systems due to the possibility of making ex…
Tunable "Doniach Phase Diagram" for strongly-correlated nanoclusters
Y. Luo, C. Verdozzi, N. Kioussis
Exact diagonalization calculations reveal that the energy spacing in the conduction band tunes the interplay between the {\it local} Kondo and {\it non local} RKKY interactions…
Zero-temperature Phase Diagram For Strongly-Correlated Nanochains
Y. Luo, C. Verdozzi, N. Kioussis
Recently there has been a resurgence of intense experimental and theoretical interest on the Kondo physics of nanoscopic and mesoscopic systems due to the possibility of making exp…
Disordered Kondo Nanoclusters: Effect of Energy Spacing
C. Verdozzi, Y. Luo, Nicholas Kioussis
Exact diagonalization results for Kondo nanoclusters alloyed with mixed valence impurities show that tuning the {\it energy spacing}, , drives the system from the Kondo to the R…
Strongly Correlated Cerium Systems: Non-Kondo Mechanism for Moment Collapse
Eric M. Collins, Nicholas Kioussis, Say Peng Lim +1
We present an ab initio based method which gives clear insight into the interplay between the hybridization, the coulomb exchange, and the crystal-field interactions, as the degree…
Precursor of Non-Fermi Liquid Behaviour in the One-Dimensional Periodic Anderson Model with Disorder
Feng Chen, Nicholas Kioussis
We have studied the one-dimensional periodic, symmetric Anderson model at half filling in the presence of disorder using finite-temperature quantum Monte Carlo techniques. We have…
