We show that, for pertinent values of the fabrication and control parameters, an attractive
finite coupling fixed point emerges in the phase diagram of a Y-junction of superconducting …

The topological Kondo (TK) model has been proposed in solid-state quantum devices as a
way to realize non-Fermi liquid behaviors in a controllable setting. Another motivation …

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 …

We analyze a perturbation of the boundary Sine-Gordon model where two boundary terms
of different periodicities and scaling dimensions are coupled to a Kondo-like spin degree of …

We use boundary field theory to describe the phases accessible to a tetrahedral qubit
coupled to Josephson junction chains acting as Tomonaga–Luttinger liquid leads. We prove …

Making a combined use of bosonization and fermionization techniques, we build nonlocal
transformations between dual fermion operators, describing junctions of strongly interacting …
