Unconventional state with two coexisting long-range orders for frustrated Heisenberg model at quantum phase transition
چکیده انگلیسی
For the frustrated two-dimensional S=1/2 antiferromagnetic Heisenberg model close to quantum phase transition we consider the singlet ground states retaining both translational and SU(2) symmetry. Besides usually discussed checkerboard, spin-liquid and stripe states an unconventional state with two coexisting long-range orders appears to be possible at sufficiently large damping of spin excitations. The problem is treated in the frames of self-consistent spherically symmetric approach.
