Tuning the Many-body Interactions in a Helical Luttinger Liquid
Junxiang Jia, Elizabeth Marcellina, Anirban Das +11
In one-dimensional (1D) systems, electronic interactions lead to a breakdown of Fermi liquid theory and the formation of a Tomonaga-Luttinger Liquid (TLL). The strength of its many…
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…
Structural and magnetic field effects on spin fluctuations in SrRuO
Shantanu Mukherjee, Wei-Cheng Lee
We investigate the evolution of magnetic excitations in SrRuO using a three band tight binding model that takes into account the influence of Mn and Ti dopant ions. The…
Tuning a Strain-Induced Orbital Selective Mott Transition in Epitaxial VO
Shantanu Mukherjee, N. F. Quackenbush, H. Paik +5
We present evidence of strain-induced modulation of electron correlation effects and increased orbital anisotropy in the rutile phase of epitaxial VO/TiO films from hard x-…
Resonant Plasmon-Axion Excitations Induced by Charge Density Wave Order in Weyl Semimetal
Matthew D. Redell, Shantanu Mukherjee, Wei-Cheng Lee
We investigate the charge excitations of a Weyl semimetal in the axionic charge density wave (axionic CDW) state. While it has been shown that the topological response (anomalous H…
