Spin-density functional study of the organic polymer dimethylaminopyrrole: A realization of the organic periodic Anderson model
Yuji Suwa, Ryotaro Arita, Kazuhiko Kuroki +1
While the periodic Anderson model (PAM) has been recognized as a good model for various heavy f-electron systems, here we design a purely organic polymer whose low-energy physics c…
Flat-band ferromagnetism proposed for an organic polymer crystal
Ryotaro Arita, Yuji Suwa, Kazuhiko Kuroki +1
Motivated from the flat-band ferromagnetism conceived theoretically for a single chain of five membered rings (polyaminotriazole) by Arita {\it et al.}, [Phys. Rev. Lett. {\bf 88},…
Flat-Band Ferromagnetism in Organic Polymers Designed by a Computer Simulation
Yuji Suwa, Ryotaro Arita, Kazuhiko Kuroki +1
By coupling a first-principles, spin-density functional calculation with an exact diagonalization study of the Hubbard model, we have searched over various functional groups for th…
Gate-induced band ferromagnetism in an organic polymer
Ryotaro Arita, Yuji Suwa, Kazuhiko Kuroki +1
We propose that a chain of five-membered rings (polyaminotriazole) should be ferromagnetic with an appropriate doping that is envisaged to be feasible with an FET structure. The fe…
