One-particle spectral functions of the one-dimensional Fermionic Hubbard model with one fermion per site at zero and finite magnetic fields
José M. P. Carmelo, Tilen Čadež, Pedro D. Sacramento
Here the line shape of the up- and down-spin one-particle spectral functions at and in the (k,energy)-plane's vicinity of their cusp singularities is studied for the Mott-Hubbard i…
Bethe strings in the spin dynamical structure factor of the Mott-Hubbard phase in one-dimensional fermionic Hubbard model
Jose M. P. Carmelo, Tilen Cadez
The spectra and role in the spin dynamical properties of bound states of elementary magnetic excitations named Bethe strings that occur in some integrable spin and electronic one-d…
Bethe strings in the dynamical structure factor of the spin-1/2 Heisenberg XXX chain
J. M. P. Carmelo, T. Cadez, P. D. Sacramento
Recently there has been a renewed interest in the spectra and role in dynamical properties of excited states of the spin-1/2 Heisenberg antiferromagnetic chain in longitudinal magn…
Spin-dependent two-photon Bragg scattering in the Kapitza-Dirac effect
Sven Ahrens, Zhenfeng Liang, Tilen Cadez +1
We present the possibility of spin-dependent Kapitza-Dirac scattering based on a two-photon interaction only. The interaction scheme is inspired from a Compton scattering process,…
Effects of finite-range interactions on the one-electron spectral properties of TTF-TCNQ
Jose M. P. Carmelo, Tilen Cadez, David K. Campbell +2
The electronic dispersions of the quasi-one-dimensional organic conductor TTF-TCNQ are studied by angle-resolved photoelectron spectroscopy (ARPES) with higher angular resolution a…
One-particle spectral function singularities in a one-dimensional gas of spin-1/2 fermions with repulsive delta-function interaction
T. Cadez, S. Nemati, J. M. P. Carmelo
The momentum, fermionic density, spin density, and interaction dependencies of the exponents that control the (momentum-energy)-plane singular features of the one-fermion spectral…
