Transport, refraction and interface arcs in junctions of Weyl semimetals
Francesco Buccheri, Reinhold Egger, Alessandro De Martino
We study the low-energy single-electron transport across a junction of two magnetic Weyl semimetals, in which the anisotropy axes are tilted one respect to the other. Using a two-b…
Phonon-limited Transport and Fermi Arc Lifetime in Weyl Semimetals
Francesco Buccheri, Alessandro De Martino, Rodrigo G. Pereira +2
Weyl semimetals harbor topological Fermi-arc surface states which determine the nontrivial charge current response to external fields. We here study the quasiparticle decay rate of…
Phonon-induced magnetoresistivity of Weyl semimetal nanowires
Alessandro De Martino, Kathrin Dorn, Francesco Buccheri +1
We study longitudinal magnetotransport in disorder-free cylindrical Weyl semimetal nanowires. Our theory includes a magnetic flux piercing the nanowire and captures the finite…
Violation of the Wiedemann-Franz law in the Topological Kondo model
Francesco Buccheri, Andrea Nava, Reinhold Egger +2
We study the thermal transport through a Majorana island connected to multiple external quantum wires. In the presence of a large charging energy, we find that the Wiedemann-Franz…
Superconductivity from piezoelectric interactions in Weyl semimetals
Rodrigo G. Pereira, Francesco Buccheri, Alessandro De Martino +1
We present an analytical low-energy theory of piezoelectric electron-phonon interactions in undoped Weyl semimetals, taking into account also Coulomb interactions. We show that pie…
Parafermionic generalization of the topological Kondo effect
Kyrylo Snizhko, Francesco Buccheri, Reinhold Egger +1
We propose and study a parafermionic generalization of the topological Kondo effect. The latter has been predicted to arise for a Coulomb-blockaded mesoscopic topological supercond…
Josephson effect in Majorana box devices
A. Zazunov, F. Buccheri, P. Sodano +1
We study Majorana devices featuring a competition between superconductivity and multi-channel Kondo physics. Our proposal extends previous work on single-channel Kondo systems to a…
Thermodynamics of the Topological Kondo Model
Francesco Buccheri, Hrachya Babujian, Vladimir E. Korepin +2
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 h…
Finite temperature one-point functions in non-diagonal integrable field theories: the sine-Gordon model
Francesco Buccheri, Gabor Takacs
We study the finite-temperature expectation values of exponential fields in the sine-Gordon model. Using finite-volume regularization, we give a low-temperature expansion of such q…
Generating function for sine-Gordon correlators in finite volume from the inhomogeneous XXZ chain
Francesco Buccheri
We present an expression for the generating function of correlation functions of the sine-Gordon integrable field theory on a cylinder, with compact space. This is derived from the…
On the structure of typical states of a disordered Richardson model and many-body localization
Francesco Buccheri, Andrea De Luca, Antonello Scardicchio
We present a thorough numerical study of the Richardson model with quenched disorder (a fully-connected XX-model with longitudinal random fields). We study the onset of delocalizat…
The integrable O(6) model and the correspondence: checks and predictions
Francesco Buccheri, Davide Fioravanti
We exactly compute the energy density of the integrable O(n) non-linear sigma model as a convergent series. This series is specifically analysed for the very important O(6) symmetr…
