Interfacial and thickness effects in LaSrMnO/YBaCuO superlattices
V. A. M. Lima, M. C. O. Aguiar, N. C. Plumb +2
Superlattices of correlated oxides have been used to explore interfacial effects and to achieve additional control over the physical properties of individual constituents. In this…
Orbital Selective Mott Transition Effects and Non-Trivial Topology of Iron Chalcogenide
Minjae Kim, Sangkook Choi, Walber Hugo Brito +1
The iron-based superconductor FeSeTe (FST) has recently gained significant attention as a host of two distinct physical phenomena: () Majorana zero modes which can…
Formation of spin and charge ordering in the extended Hubbard model during a finite-time quantum quench
Isaac M. Carvalho, Helena Bragança, Walber H. Brito +1
We investigate the formation of charge and spin ordering by starting from a non-interacting state and studying how it evolves in time under a Hamiltonian with finite electronic int…
Reconstruction of low dimensional electronic states by altering the chemical arrangement at the SrTiO3 surface
Hang Li, Walber H. Brito, Eduardo B. Guedes +9
Developing reliable methods for modulating the electronic structure of the two-dimensional electron gas (2DEG) in SrTiO3 is crucial for utilizing its full potential and inducing no…
Correlation strength and orbital differentiation across the phase diagram of plutonium metal
W. H. Brito, G. Kotliar
We compare the trends on the strength of electronic correlations across the different phases of elemental Pu focusing on its site and orbital dependence, using a combination of den…
Site and orbital selective correlations in -Pu
W. H. Brito, G. Kotliar
We investigate the electronic structure of the highly anisotropic phase of metallic plutonium, within the combination of density functional theory (DFT) and dynamical mean fiel…
Anisotropic Correlated Electronic Structure of Colossal Thermopower Marcasite FeSb
A. Chikina, J. -Z. Ma, W. H. Brito +9
Iron antimonide (FeSb) is a mysterious material with peculiar colossal thermopower of about mV/K at 10 K. However, a unified microscopic description of this phenomenon is…
Unusual electronic and vibrational properties in the colossal thermopower material FeSb
C. C. Homes, Q. Du, C. Petrovic +3
The iron antimonide FeSb possesses an extraordinarily high thermoelectric power factor at low temperature, making it a leading candidate for cryogenic thermoelectric cooling de…
