Z parafermion zero modes without Fractional Quantum Hall effect
A. M. Tsvelik
I discuss a one-dimensional model of interacting fermions which collective excitations are Z-parafermions. The phase diagram of this model contains ground states with Charge De…
An integrable model with parafermion zero energy modes
A. M. Tsvelik
Parafermion zero energy modes are a vital element of fault-tolerant topological quantum computation. Although it is believed that such modes form on the border between topological…
Composite charge order in the pseudogap region of the cuprates
A. M. Tsvelik, A. V. Chubukov
We study the Ginzburg-Landau free energy functional for two coupled U(1) charge order parameters describing two non-equivalent charge orders with wave vector detected in…
Bethe ansatz solution of the topological Kondo model
A. Altland, B. Beri, R. Egger +1
Conduction electrons coupled to a mesoscopic superconducting island hosting Majorana bound states have been shown to display a topological Kondo effect with robust non-Fermi liquid…
Topological Kondo effect in star junctions of Ising magnetic chains. Exact solution
A. M. Tsvelik
In this paper I present a conjecture for the Bethe ansatz equations for the model describing a star junction of quantum critical Ising chains. For such model exhibits the…
