Two-channel Kondo problem in coupled interacting helical liquids
Sourav Biswas, Alessandro De Martino, Sumathi Rao +1
We study the two-channel Kondo problem in the context of two interacting helical liquids coupled to a spin- magnetic impurity. We show that the interactions between the tw…
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…
Spin-orbit coupling and electron spin resonance for interacting electrons in carbon nanotubes
A. De Martino, R. Egger, F. Murphy-Armando +1
We review the theoretical description of spin-orbit scattering and electron spin resonance in carbon nanotubes. Particular emphasis is laid on the effects of electron-electron inte…
Spin-orbit coupling and ESR theory for carbon nanotubes
A. De Martino, R. Egger, K. Hallberg +1
A theoretical description of ESR in 1D interacting metals is given, with primary emphasis on carbon nanotubes. The spin-orbit coupling is derived, and the resulting ESR spectrum is…
ESR theory for interacting 1D quantum wires
A. De Martino, R. Egger
We compute the electron spin resonance (ESR) intensity for one-dimensional quantum wires in semiconductor heterostructures, taking into account electron-electron interactions and s…
Hubbard ladders in a magnetic field
D. C. Cabra, A. De Martino, P. Pujol +1
The behavior of a two leg Hubbard ladder in the presence of a magnetic field is studied by means of Abelian bosonization. We predict the appearance of a new (doping dependent) plat…
Emergence of Irrationality: Magnetization Plateaux in Modulated Hubbard Chains
D. C. Cabra, A. De Martino, A. Honecker +2
Hubbard chains with periodically modulated coupling constants in a magnetic field exhibit gaps at zero temperature in their magnetic and charge excitations in a variety of situatio…
Random bond XXZ chains with modulated couplings
D. C. Cabra, A. De Martino, M. D. Grynberg +2
The magnetization behavior of q-periodic antiferromagnetic spin 1/2 Heisenberg chains under uniform magnetic fields is investigated in a background of disorder exchange distributio…
Doping-dependent magnetization plateaux in p-merized Hubbard chains
D. C. Cabra, A. De Martino, A. Honecker +2
We study zero-temperature Hubbard chains with periodically modulated hopping at arbitrary filling n and magnetization m. We show that the magnetization curves have plateaux at cert…
