We analyze the dynamics of the helical edge modes of a quantum spin Hall state in the presence of a spatially nonuniform Rashba spin-orbit (SO) interaction. A randomly fluctuating Rashba SO couplingâ€¦ (More)

We have studied the ground-state phase diagram of a two-leg spin ladder with anisotropic ferromagnetic leg couplings under the influence of a symmetry-breaking transverse magnetic field by the exactâ€¦ (More)

A one-dimensional model of interacting electrons with on-site U, nearest-neighbor V, and correlatedhopping interactionT* is studied at half filling using the continuum-limit field theory approach.â€¦ (More)

In this paper we study the ground state phase diagram of a one-dimensional t âˆ’ U âˆ’ J model, at half-filling. In the large-bandwidth limit and for ferromagnetic exchange with easy-plane anisotropy, aâ€¦ (More)

The ground-state magnetic phase diagram of a spin S = 1/2 two-leg ladder with alternating rung exchange J âŠ¥ (n) = J âŠ¥ [1 + (âˆ’1) n Î´] is studied using the analytical and numerical approaches. In theâ€¦ (More)
