Spin density wave formation in graphene facilitated by the in-plane magnetic field
D. E. Kharzeev, S. A. Reyes, A. M. Tsvelik
We suggest that by applying a magnetic field lying in the plane of graphene layer one may facilitate an excitonic condensation of electron-hole pairs with opposite spins and chiral…

Finite temperature correlation function for one-dimensional Quantum Ising model: the virial expansion
S. A. Reyes, A. M. Tsvelik
We rewrite the exact expression for the finite temperature two-point correlation function for the magnetization as a partition function of some field theory. This removes singulari…

Crossed spin-1/2 Heisenberg chains as a quantum impurity problem
S. A. Reyes, A. M. Tsvelik
Using equivalencies between different models we reduce the model of two spin-1/2 Heisenberg chains crossed at one point to the model of free fermions. The spin-spin correlation fun…
