Multichannel Kondo impurity dynamics in a Majorana device.
نویسندگان
چکیده
We study the multichannel Kondo impurity dynamics realized in a mesoscopic superconducting island connected to metallic leads. The effective "impurity spin" is nonlocally realized by Majorana bound states and strongly coupled to lead electrons by non-Fermi liquid correlations. We explore the spin dynamics and its observable ramifications near the low-temperature fixed point. The topological protection of the system raises the perspective to observe multichannel Kondo impurity dynamics in experimentally realistic environments.

Multichannel Kondo approach to the cuprate and recent laser ARPES data
The existing theoretical approaches have been unable to confront the large corpus of outstanding data on the cuprate superconductor in a persuasive and unified manner. There is a general opinion now growing that these theories miss some essential points. We propose one based on multichannel Kondo effect that is physically justifiable and confronts the data adequately. In addition to earlier da...
متن کاملFermi- and non-Fermi-liquid behavior in the anisotropic multichannel Kondo model: Bethe Ansatz solution.
We solve the Multichannel Kondo model with channel anisotropy using the Bethe Ansatz method. The model generates energy scales, characterizing the neighborhoods of the various infrared fixed points, reflecting the structure of the symmetry breaking in the channel sector. The nature of these fixed points also depends on the magnitude of the impurity spin S. We present a detailed discussion for t...
متن کاملMultichannel Kondo screening in a one-dimensional correlated electron system
We study a multichannel one-dimensional (1D) supersymmetric t−J model with an added magnetic impurity of arbitrary spin S. The antiferromagnetic impurity-electron interaction is chosen so as to preserve integrability, allowing for an exact diagonalization of the model by a Bethe Ansatz. The solution reveals that interactions in the bulk make the magnetic impurity drive both spin and charge fluc...
متن کاملMultichannel pseudogap Kondo model: large-N solution and quantum-critical dynamics.
We discuss a multichannel SU(N) Kondo model which displays nontrivial zero-temperature phase transitions due to a conduction electron density of states vanishing with a power law at the Fermi level. In a particular large- N limit, the system is described by coupled integral equations corresponding to a dynamic saddle point. We exactly determine the universal low-energy behavior of spectral dens...
متن کاملExotic Kondo Effects in Metals: Magnetic Ions in a Crystalline Electric Field and Tunneling Centers
The ordinary single channel Kondo model consists of one or more spin 1/2 local moments interacting antiferromagnetically with conduction electrons in a metal. This model has provided a paradigm for understanding many phenomena of strongly correlated electronic materials, ranging from the formation of heavy fermion fermi liquids to the mapping to a one-band model in the cuprate superconductors. ...
