Quantum transport in Dirac and Weyl semimetals: a review
TL;DR: In this paper, the angle resolved photoemissio-graph was used for the linear energy band dispersion in the bulk state and topologically protected surface state with arc-like Fermi surface.

The spectral gap for some spin chains with discrete symmetry breaking
TL;DR: In this article, it was shown that for any finite set of generalized valence bond solid (GVBS) states of a quantum spin chain there exists a translation invariant finite-range Hamiltonian for which this set is the set of ground states.

Gauge Theory and Integrability, II
TL;DR: In this article, a four-dimensional gauge theory approach to rational, elliptic, and trigonometric solutions of the Yang-Baxter equation is used to determine the corresponding quantum group deformations to all orders in $\hbar$ by deducing their RTT presentations.

Integrable Hamiltonian systems and interactions through quadratic constraints
TL;DR: In this article, the relativistic field theories in one time and one space dimension with interactions that are entirely due to quadratic constraints are shown to be closely related to integrable Hamiltonian systems.

Interaction of Goldstone Particles in Two-Dimensions. Applications to Ferromagnets and Massive Yang-Mills Fields
TL;DR: In this paper, it is shown that due to interaction the regime of the asymmptotic freedom arises and the continuation to higher dimensions and the applications of the result are briefly discussed.

What is the spin of a spin wave
L. D. Faddeev,L.A. Takhtajan +1 more
TL;DR: In this paper, it was shown that the spin of a spin wave in the Heisenberg antiferromagnetic chain of spins 1 2 is equal to 1 2 rather than 1 as is generally considered to be true.
