The Electron-Phonon Interaction of Low-Dimensional and Multi-Dimensional Materials from He Atom Scattering
G. Benedek, J. R. Manson, S. Miret-Artés
Atom scattering is becoming recognized as a sensitive probe of the electron-phonon interaction parameter at metal and metal-overlayer surfaces. Here, the theory is developed li…
Electron-Phonon Coupling Constant of Metallic Overlayers from Specular He-Atom Scattering
G. Benedek, Salvador Miret-Artes, J. R. Manson +1
He atom scattering has been shown to be a sensitive probe of electron-phonon interaction properties at surfaces. Here it is shown that measurements of the thermal attenuation of th…
Majorana Fermions in Chiral Topological Ferromagnetic Nanowires
Eugene Dumitrescu, Brenden Roberts, Sumanta Tewari +2
Motivated by a recent experiment in which zero-bias peaks have been observed in scanning tunneling microscopy (STM) experiments performed on chains of magnetic atoms on a supercond…
Majorana Fermions Under Uniaxial Stress in Semiconductor-Superconductor Heterostructures
Ming Gong, Li Mao, Sumanta Tewari +1
Spin-orbit coupled semiconductor nanowires with Zeeman splitting in proximity contact with bulk -wave superconductivity have recently been proposed as a promising platform for r…
Topologically non-trivial superconductivity in spin-orbit coupled systems: Bulk phases and quantum phase transitions
Sumanta Tewari, Tudor D. Stanescu, Jay D. Sau +1
Topologically non-trivial superconductivity has been predicted to occur in superconductors with a sizable spin-orbit coupling in the presence of an external Zeeman splitting. Two s…
Soft phonons and structural phase transition in superconducting Ba0.59K0.41BiO3
H. J. Kang, Y. S. Lee, J. W. Lynn +2
We have observed a softening of phonons and a structural phase transition in a superconducting Ba0.59K0.41BiO3 (Tc = 31 K) single crystal using elastic and inelastic neutron scatte…
