Carrier-density effects in many-polaron systems
Martin Hohenadler, Georg Hager, Gerhard Wellein +1
Many-polaron systems with finite charge-carrier density are often encountered experimentally. However, until recently, no satisfactory theoretical description of these systems was…
Phase diagram of the spin-Peierls chain with local coupling
Alexander Weisse, Georg Hager, Alan R. Bishop +1
We explore the ground-state phase diagram of a Heisenberg spin chain coupled locally to optical phonons (bond coupling), using large-scale density matrix renormalization group calc…
The spin-Peierls chain revisited
Georg Hager, Alexander Weisse, Gerhard Wellein +2
We extend previous analytical studies of the ground-state phase diagram of a one-dimensional Heisenberg spin chain coupled to optical phonons, which for increasing spin-lattice cou…
