Influence of electron-phonon coupling on low temperature phases of metallic single-wall carbon nanotubes
Junichi Okamoto, Ludwig Mathey, Wen-Min Huang
We investigate the effect of electron-phonon coupling on low temperature phases in metallic single-wall carbon nanotubes. We obtain low-temperature phase diagrams of armchair and z…
Electron trimer states in conventional superconductors
Ali Sanayei, Pascal Naidon, Ludwig Mathey
We expand the Cooper problem by including a third electron in an otherwise empty band. We demonstrate the formation of a trimer state of two electrons above the Fermi sea and the t…
Squeezed field path integral description of second sound in Bose-Einstein condensates
Ilias M. H. Seifie, Vijay Pal Singh, L. Mathey
We propose a generalization of the Feynman path integral using squeezed coherent states. We apply this approach to the dynamics of Bose-Einstein condensates, which gives an effecti…
Light-induced coherence in an atom-cavity system
Christoph Georges, Jayson G. Cosme, Ludwig Mathey +1
We demonstrate light-induced formation of coherence in a cold atomic gas system that utilizes the suppression of a competing density wave (DW) order. The condensed atoms are placed…
Dynamical Control of Order in a Cavity-BEC System
Jayson G. Cosme, Christoph Georges, Andreas Hemmerich +1
We demonstrate dynamical control of the superradiant transition of cavity-BEC system via periodic driving of the pump laser. We show that the dominant density wave order of the sup…
