PROPERTIES OF THE SOLITON-LATTICE STATE IN DOUBLE-LAYER QUANTUM HALL SYSTEMS

Application of a sufficiently strong parallel magnetic field B-paralle l to > B-c produces a soliton-lattice (SL) ground state in a double-la yer quantum Hall system. We calculate the ground-state properties of t he SL state as a function of B-parallel to for total filling factor v( T) = 1, and obtain the total energy, anisotropic SL stiffness, Kosterl itz-Thouless melting temperature, and SL magnetization. The SL magneti zation might be experimentally measurable, and the magnetic susceptibi lity diverges as \B-parallel to - B-c\(-1). (C) 1998 Elsevier Science B.V. All rights reserved.
