Quantum transitions from superfluid to insulating phases in disordered Bose systems
A. V. Syromyatnikov, F. D. Timkovskii
By the example of Heisenberg -dimensional disordered non-frustrated antiferromagnets, we discuss quantum transitions at from magnetically ordered (superfluid) to various…

Antiferromagnets with random vacancies and substitutional spins on the triangular lattice
A. V. Syromyatnikov, F. D. Timkovskii
We discuss theoretically static and dynamical properties of and Heisenberg antiferromagnets on triangular lattice with random vacancies and substitutional spins. It is shown t…

Critical temperature and low-energy excitations in gapped spin systems with defects
F. D. Timkovskii, A. V. Syromyatnikov
We discuss theoretically the magnetically ordered phase induced by magnetic and nonmagnetic impurities in three-dimensional and quasi-low-dimensional systems with singlet ground st…
