Electron-phonon scattering in topological insulator thin films
Sébastien Giraud, Arijit Kundu, Reinhold Egger
We present a theoretical study of electron-phonon scattering effects in thin films made of a strong topological insulator. Phonons are modelled by isotropic elastic continuum theor…
Interaction beween polarons and analogous effects in polarized Fermi gases
S. Giraud, R. Combescot
We consider an imbalanced mixture of two different ultracold Fermi gases, which are strongly interacting. Calling spin-down the minority component and spin-up the majority componen…
Electron-phonon scattering in topological insulators
Sébastien Giraud, Reinhold Egger
We formulate and apply a theory of electron-phonon interactions for the surface state of a strong topological insulator. Phonons are modelled using an isotropic elastic continuum t…
Comment on "Motion of an impurity particle in an ultracold quasi-one-dimensional gas of hard-core bosons [Phys. Rev. A 79, 033610 (2009)]"
S. Giraud, R. Combescot
Very recently Girardeau and Minguzzi [arXiv:0807.3366v2, Phys. Rev. A 79, 033610 (2009)] have studied an impurity in a one-dimensional gas of hard-core bosons. In particular they d…
Analytical theory of the dressed bound state in highly polarized Fermi gases
R. Combescot, S. Giraud, X. Leyronas
We present an analytical treatment of a single \down atom within a Fermi sea of \up atoms, when the interaction is strong enough to produce a bound state, dressed by the Fermi sea.…
Highly polarized Fermi gases: One-dimensional case
S. Giraud, R. Combescot
We consider the problem of a single particle interacting with identical fermions, at zero temperature and in one dimension. We calculate the binding energy as well as the effec…
