Fragmentation Temperature of 1D and 3D Quantum Droplets in a BEC Mixture
Jeroen Van Loock, Denise Ahmed-Braun, Jacques Tempere
In a mixture of two Bose-Einstein condensates, the interactions can be tuned such that self-bound objects called quantum droplets appear. Whereas the ground states of such quantum…
Dispersion of plasmons in three-dimensional superconductors
T. Repplinger, S. Klimin, M. Gélédan +2
We study the plasma branch of an homogeneous three-dimensional electron gas in an -wave superconducting state. We focus on the regime where the plasma frequency is compar…
First-principles theory of nonlinear long-range electron-phonon interaction
Matthew Houtput, Luigi Ranalli, Carla Verdi +4
Describing electron-phonon interactions in a solid requires knowledge of the electron-phonon matrix elements in the Hamiltonian. State-of-the-art first-principles calculations for…
First-principles theory of nonlinear long-range electron-phonon interaction
Matthew Houtput, Luigi Ranalli, Carla Verdi +4
Electron-phonon interactions in solids are crucial for understanding many interesting phenomena, such as conventional superconductivity, temperature-dependent band-gap renormalizat…
