Recent advances in the generation of well-characterized subfemtosecond laser pulses have
opened up unpredicted opportunities for the real-time observation of ultrafast electronic …

We study the symmetries of closed Majorana chains in 1+ 1d, including the translation,
fermion parity, spatial parity, and time-reversal symmetries. The algebra of the symmetry …

We establish results similar to Kramers and Lieb-Schultz-Mattis theorems but involving only
translation symmetry and for Majorana modes. In particular, we show that all states are at …

We study the multichannel Kondo impurity dynamics realized in a mesoscopic
superconducting island connected to metallic leads. The effective “impurity spin” is …

Ejection of an electron by absorption of an extreme ultraviolet (xuv) photon probes the many-
electron response of a solid well beyond the single-particle picture. Photoemission spectra …

We derive the topological Kondo Hamiltonian describing a Y junction of three XX-spin
chains connected to outer quantum Ising chains with different tilting angles for the Ising axis …

We propose and study a setup realizing a stable manifold of non-Fermi-liquid states. The
device consists of a mesoscopic superconducting island hosting N≥ 3 Majorana bound …

Ettore Majorana contributed several ideas that have had significant, lasting impact in
condensed matter physics, broadly construed. Here I will discuss, from a modern …

Using the thermodynamic Bethe ansatz, we investigate the topological Kondo model, which
describes a set of one-dimensional external wires, pertinently coupled to a central region …
