Energy Landscape analysis of metal-insulator transitions: theory and application to CaRuO, NiO and their heterostructures
Alexandru B. Georgescu, Andrew J. Millis
We present a general methodology that enables the disentanglement of the electronic and lattice contributions to the metal-insulator transition by building an energy landscape from…
Hartree-Fock study of the moiré Hubbard model for twisted bilayer transition metal dichalcogenides
Jiawei Zang, Jie Wang, Jennifer Cano +1
Twisted bilayer transition metal dichalcogenides have emerged as important model systems for the investigation of correlated electron physics because their interaction strength, ca…
Quantum Criticality in Twisted Transition Metal Dichalcogenides
Augusto Ghiotto, En-Min Shih, Giancarlo S. S. G. Pereira +10
In moiré heterostructures, gate-tunable insulating phases driven by electronic correlations have been recently discovered. Here, we use transport measurements to characterize the g…
Fizeau Drag in Graphene Plasmonics
Y. Dong, L. Xiong, I. Y. Phinney +16
Dragging of light by moving dielectrics was predicted by Fresnel and verified by Fizeau's celebrated experiments with flowing water. This momentous discovery is among the experimen…
Dependence of DFT+DMFT Results on the Construction of the Correlated Orbitals
Jonathan Karp, Alexander Hampel, Andrew J. Millis
The sensitivity of Density Functional Theory plus Dynamical Mean Field Theory calculations to different constructions of the correlated orbitals is investigated via a detailed comp…
Second order Josephson effect in excitonic insulators
Zhiyuan Sun, Tatsuya Kaneko, Denis Golež +1
We show that in electron-hole bilayers with excitonic order arising from conduction and valence bands formed by atomic orbitals that have different parities, nonzero interlayer tun…
