Phase Transitions and Pairing Signature in Strongly Attractive Fermi Atomic Gases
X W Guan, M T Batchelor, C Lee +1
We investigate pairing and quantum phase transitions in the one-dimensional two-component Fermi atomic gas in an external field. The phase diagram, critical fields, magnetization a…

Quantum versus classical behavior in the boundary susceptibility of the ferromagnetic Heisenberg chain
J. Sirker, M. Bortz
We calculate the temperature dependence of the boundary susceptibility for the quantum ferromagnetic Heisenberg chain by a modified spin-wave theory (MSWT). We find that $χ_B…

Boundary susceptibility in the open XXZ-chain
Michael Bortz, Jesko Sirker
In the first part we calculate the boundary susceptibility in the open -chain at zero temperature and arbitrary magnetic field by Bethe ansatz. We present analytical…
