Asymmetric magnetoresistance in 3-5 based LaCaMnO/SrIrO bilayer: The role of unidirectional anisotropy
A. G. A. Rahman, Subham Naskar, R. K. Patel +4
The complex interplay between spin-orbit coupling, magnetism, and magnetic field at the interface of a heterostructure consisting of ferromagnet (FM) and heavy metal (HM), often ex…
Magnetic excitations and exchange parameters of a nickel chain compound PbMnNiTeO: Neutron scattering and density functional theory studies
S. Uthayakumar, D. T. Adroja, Amit Pokhriyal +10
We have investigated the quasi-one dimensional Ni-chain compound PbMnNiTeO using theoretical DFT calculations, inelastic neutron scattering and optical spectrosc…
Terahertz-driven ultrafast dynamics of rare-earth nickelates by controlling only the charge degree of freedom
Gulloo Lal Prajapati, Sergey Kovalev, Igor Ilyakov +5
An important strategy for understanding the microscopic physics of strongly correlated systems and enhancing their technological potential is to selectively drive the fundamental d…
Gapless deconfined phase in a symmetric Hamiltonian created in a cold-atom setup
Mykhailo V. Rakov, Luca Tagliacozzo, Maciej Lewenstein +2
We investigate a quasi-two-dimensional system consisting of two species of alkali atoms confined in a specific optical lattice potential [Phys. Rev. A 95, 053608 (2017)]. In the lo…
Emergence of non-Abelian SU(2) invariance in Abelian frustrated fermionic ladders
Bachana Beradze, Mikheil Tsitsishvili, Emanuele Tirrito +3
We consider a system of interacting spinless fermions on a two-leg triangular ladder with magnetic flux per triangular plaquette. Microscopically, the system exhibits a U(1)…
Spectroscopic comprehension of Mott-Hubbard insulator to negative charge transfer metal transition in LaNi_{x}V_{1-x}O_{3} thin films
Anupam Jana, Sophia Sahoo, Sourav Chowdhury +4
The room temperature (300 K) electronic structure of pulsed laser deposited LaNi_{x}V_{1-x}O_{3} thin films have been demonstrated. The substitution of early-transition metal (TM)…
