Theory of small charge solitons in one-dimensional arrays of Josephson junctions
Stephan Rachel, Alexander Shnirman
We identify and investigate the new parameter regime of small charge solitons in one-dimensional arrays of Josephson junctions. We obtain the dispersion relation of the soliton and…

Spontaneous Parity Violation in a Quantum Spin Chain
Stephan Rachel, Dirk Schuricht, Burkhard Scharfenberger +2
We report on a spontaneous breakdown of parity in the ground state of a spin Hamiltonian involving nearest-neighbor interactions. This occurs for a one-dimensional model where spin…
