Dynamics of quantum spin chains and multi-fermion excitation continua
O. Derzhko, T. Krokhmalskii, J. Stolze +1
We use the Jordan-Wigner representation to study dynamic quantities for the spin-1/2 XX chain in a transverse magnetic field. We discuss in some detail the properties of the four-f…
Transition rates via Bethe ansatz for the spin-1/2 Heisenberg chain
Daniel Biegel, Michael Karbach, Gerhard Muller
We use the exact determinantal representation derived by Kitanine, Maillet, and Terras for matrix elements of local spin operators between Bethe wave functions of the one-dimension…
Quasiparticles governing the zero-temperature dynamics of the 1D spin-1/2 Heisenberg antiferromagnet in a magnetic field
Michael Karbach, Daniel Biegel, Gerhard Muller
The T=0 dynamical properties of the one-dimensional (1D) Heisenberg antiferromagnet in a uniform magnetic field are studied via Bethe ansatz for cyclic chains of sites.…
Lineshape predictions via Bethe ansatz for the one-dimensional spin-1/2 Heisenberg antiferromagnet in a magnetic field
Michael Karbach, Gerhard Muller
The spin fluctuations parallel to the external magnetic field in the ground state of the one-dimensional (1D) s=1/2 Heisenberg antiferromagnet are dominated by a two-parameter set…
