TLDR

Anomalous domain wall condensation in a modified Ising chain
TL;DR: In this article, a one-dimensional local spin Hamiltonian with an intrinsically non-local, and therefore anomalous, global symmetry was constructed, which is closely related to the quantum Ising model in a transverse magnetic field.

Pair-Hopping Mechanism for Layered Superconductors
TL;DR: In this paper, a possible charge fluctuation effect expected in layered superconducting materials is proposed, where the charging effect of a layer is comparable to the pair hopping in the Coulomb repulsion.

Doping effect on spin-Peierls instability.
Zhong-Yi Lu,Zhao-Bin Su,Lu Yu +2 more
TL;DR: A theory of SP transition in doped systems is proposed explaining findings and making further predictions on a gapleat SP state to be checked by experiments, which is rather similar to superconductors doped with paramagnetic impurities which reduce the energy gap and eventually give rise to gapless superconductivity.

Symmetry-protected adiabatic quantum transistors
TL;DR: In this paper, the performance of quantum logic gates is shown to depend only on universal symmetry properties of a symmetry-protected (SP) phase rather than any fine tuning of the Hamiltonian, and it is possible to implement a universal set of logic gates in this way by combining several different types of SP matter.

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.
