High field properties of geometrically frustrated magnets
M. E. Zhitomirsky, H. Tsunetsugu
Above the saturation field, geometrically frustrated quantum antiferromagnets have dispersionless low-energy branches of excitations corresponding to localized spin-flip modes. Tra…
Anisotropy of the upper critical field in MgB2: the two-gap Ginzburg-Landau theory
V. H. Dao, M. E. Zhitomirsky
The upper critical field in MgB2 is investigated in the framework of the two-gap Ginzburg-Landau theory. A variational solution of linearized Ginzburg-Landau equations agrees well…
Comment on "Order parameter of A-like 3He phase in aerogel"
V. P. Mineev, M. E. Zhitomirsky
We argue that the inhomogeneous A-phase in aerogel is energetically more preferable than the "robust" phase suggested by I. A. Fomin, JETP Lett. 77, 240 (2003); cond-mat/0302117 an…
Monte Carlo study of first-order transition in Heisenberg fcc antiferromagnet
M. V. Gvozdikova, M. E. Zhitomirsky
Nearest-neighbor Heisenberg antiferromagnet on a face-centered cubic lattice is studied by extensive Monte Carlo simulations in zero magnetic field. The parallel tempering algorith…
Effective quantum dimer model for trimerized kagome antiferromagnet
M. E. Zhitomirsky
An effective spin-orbit Hamiltonian is derived for a spin-1/2 trimerized kagome antiferromagnet in the second-order of perturbation theory in the ratio of two coupling constants. L…
