Inelastic magnetic scattering effect on LDOS of topological insulators
Peter Thalmeier, Alireza Akbari
Magnetic ions such as Fe, Mn and Co with localized spins may be adsorbed on the surface of topological insulators like \Bi. They form scattering centers for the helical surface sta…
Field induced spin exciton doublet splitting in d_{x^2-y^2}-wave 115-heavy electron superconductors
Alireza Akbari, Peter Thalmeier
We investigate the spin-exciton modes in the superconducting d_{x^2-y^2} state of CeMIn_5 heavy fermion compounds found at the antiferromagnetic wave vector by inelastic neutron sc…
Theory of nonequilibrium dynamics of multiband superconductors
Alireza Akbari, Andreas P. Schnyder, Dirk Manske +1
We study the nonequilibrium dynamics of multiband BCS superconductors subjected to ultrashort pump pulses. Using density-matrix theory, the time evolution of the Bogoliubov quasipa…
Challenges in Truncating the Hierarchy of Time-Dependent Reduced Density Matrices Equations: Open Problems
Ali Akbari, Mohammad Javad Hashemi, Risto M. Nieminen +2
In this work, we analyze the Born, Bogoliubov, Green, Kirkwood and Yvon (BBGKY) hierarchy of equations for describing the full time-evolution of a many-body fermionic system in ter…
Spin Exciton Formation inside the Hidden Order Phase of CeB6
Alireza Akbari, Peter Thalmeier
The heavy fermion metal CeB6 exhibits hidden order of antiferroquadrupolar (AFQ) type below T_Q=3.2K and subsequent antiferromagnetic (AFM) order at T_N=2.3K. It was interpreted as…
