Surface state evolution induced by magnetic order in axion insulator candidate EuIn2As2
Mingda Gong, Divyanshi Sar, Joel Friedman +4
Gapping of Dirac surface states through time reversal symmetry breaking may realize the axion insulator state in condensed matter. Despite tremendous efforts, only a few material s…
The Breakdown of Mott Physics at VO Surfaces
Matthew J. Wahila, Nicholas F. Quackenbush, Jerzy T. Sadowski +12
Transition metal oxides such as vanadium dioxide (VO), niobium dioxide (NbO), and titanium sesquioxide (TiO) are known to undergo a temperature-dependent metal-insu…
Emergent charge order near the doping-induced Mott-insulating quantum phase transition in SrRuO
Justin Leshen, Mariam Kavai, Ioannis Giannakis +5
We investigate the double layered Sr(RuMn)O and its doping-induced quantum phase transition (QPT) from a metal to an antiferromagnetic (AFM) Mott in…
Cooperative Effects of Strain and Electron Correlation in Epitaxial VO2 and NbO2
Wei-Cheng Lee, Matthew J. Wahila, Shantanu Mukherjee +9
We investigate the electronic structure of the epitaxial VO films in the rutile phase using the density functional theory combined with the slave spin method (DFT+SS). In DFT-S…
Importance of orbital fluctuations for the magnetic dynamics in heavy-fermion compound SmB
Christopher N. Singh, Wei-Cheng Lee
The emergent dynamical processes associated with magnetic excitations in heavy-fermion SmB are investigated. By imposing multiorbital interactions on a first-principles model,…
Revisit of Antiferromagnetism in Hubbard Model by A Cluster Slave-Spin Method
Wei-Cheng Lee, Ting-Kuo Lee
The cluster slave-spin method is introduced to systematically investigate the solutions of the Hubbard model including the symmetry-broken phases. In this method, the electron oper…
