Surface dipole of F4TCNQ films: Collective charge transfer and dipole-dipole repulsion in submonolayers
Zoltán G. Soos, Benjamin J. Topham
A charge transfer (CT) model is introduced for strong acceptors like A = F4TCNQ that are ionized on surfaces at low coverage θ. Each A forms a CT dimer with a surface state S. Dipo…
Bond order wave (BOW) phase of the extended Hubbard model: Electronic solitons, paramagnetism, coupling to Peierls and Holstein phonons
Manoranjan Kumar, Zolt'an G. Soos
The bond order wave (BOW) phase of the extended Hubbard model (EHM) in one dimension (1D) is characterized at intermediate correlation by exact treatment of -site syste…
Magnetic susceptibility of alkali-TCNQ salts and extended Hubbard models with bond order and charge density wave phases
Manoranjan Kumar, Benjamin J. Topham, Rui Hui Yu +2
The molar spin susceptibilities of Na-TCNQ, K-TCNQ and Rb-TCNQ(II) are fit quantitatively to 450 K in terms of half-filled bands of three one-dimensional Hubbard models with…
Bond-order wave phase, spin solitons and thermodynamics of a frustrated linear spin-1/2 Heisenberg antiferromagnet
Manoranjan Kumar, S. Ramasesha, Z. G. Soos
The linear spin-1/2 Heisenberg antiferromagnet with exchanges , between first and second neighbors has a bond-order wave (BOW) phase that starts at the fluid-dimer trans…
