Magnetism between magnetic adatoms on monolayer NbSe
S. Sarkar, F. Cossu, P. Kumari +4
In this work, we report on an computational study of the electronic and magnetic properties of transition metal adatoms on a monolayer of NbSe. We demonstrate that…
Surface step states and Majorana end states in profiled topological insulator thin films
Peter Thalmeier, Alireza Akbari
The protected helical surface states in thin films of topological insulators (TI) are subject to inter-surface hybridisation. This leads to gap opening and spin texture changes as…
Gapped Dirac cones and spin texture in thin film topological insulator
Peter Thalmeier, Alireza Akbari
The protected surface states of topological insulators (TIs) form gapless Dirac cones corresponding non-degenerate eigenstates with helical spin polarisation. The presence of a war…
Strain-induced stripe phase in charge ordered single layer NbSe
Fabrizio Cossu, Krisztián Palotás, Sagar Sarkar +2
Charge density waves are ubiquitous phenomena in metallic transition metal dichalcogenides. In NbSe, a triangular structural modulation is coupled to a charge modula…
Unveiling hidden charge density waves in single-layer NbSe by impurities
Fabrizio Cossu, Ali G. Moghaddam, Kyoo Kim +4
We employ {\it{ab-initio}} calculations to investigate the charge density waves in single-layer NbSe, and we explore how they are affected by transition metal atoms. Our calcul…
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…
