Majorana-metal transition in a disordered superconductor: percolation in a landscape of topological domain walls
V. A. Zakharov, I. C. Fulga, G. Lemut +2
Most superconductors are thermal insulators. A disordered chiral -wave superconductor, however, can make a transition to a thermal metal phase. Because heat is then tra…
Luttinger liquid tensor network: sine versus tangent dispersion of massless Dirac fermions
V. A. Zakharov, S. Polla, A. Donís Vela +4
To apply the powerful many-body techniques of tensor networks to massless Dirac fermions one wants to discretize the Hamiltonian and construct a matrix-product-operator (…
Efficient discrimination between real and complex quantum theories
Josep Batle, Tomasz Białecki, Tomasz Rybotycki +2
We improve the test to show the impossibility of a quantum theory based on real numbers by a larger ratio of complex-to-real bound on a Bell-type parameter. In contrast to previous…
Cross-platform certification of the qubit space with a minimal number of parameters
Tomasz Rybotycki, Tomasz Białecki, Josep Batle +2
We demonstrate a determinant dimension witness of a qubit space. Our test has a minimal number of independent parameters. We achieve it by mapping the Bloch sphere -rotation a…
Transport effects of twist-angle disorder in mesoscopic twisted bilayer graphene
Aleksander Sanjuan Ciepielewski, Jakub Tworzydło, Timo Hyart +1
Magic-angle twisted bilayer graphene is a tunable material with remarkably flat energy bands near the Fermi level, leading to fascinating transport properties and correlated states…
Helical Luttinger liquid on a space-time lattice
V. A. Zakharov, J. Tworzydlo, C. W. J. Beenakker +1
The Luttinger model is a paradigm for the breakdown due to interactions of the Fermi liquid description of one-dimensional massless Dirac fermions. Attempts to discretize the model…
