Magnetized States of Quantum Spin Chains

Long-range spin chirality dimer order in the Heisenberg chain with modulated Dzyaloshinskii-Moriya interactions

“…Quantum spin chains continue to be the subject of intensive studies because they serve as interesting model systems to explore strongly correlated quantum order in low dimensional magnetic systems [1][2][3]. A significant fraction of current research is focused on studies of helical structures and chiral order in the frustrated quantum magnetic systems [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

From order to randomness: Onset and evolution of the random-singlet state in bond-disordered BaCu2(Si1−xGex)2Shiroka1, Eggenschwiler2, Ott3 et al. 2019Phys. Rev. B10150View full textAdd to dashboardCite

“…It is known for some time that the series of BaCu 2 (Si 1−x -Ge x ) 2 O 7 compounds represents one of the best physical realizations of an S = 1/2 Heisenberg-type spin-chain system (see, e.g., Table 1 in Ref. 17), where bond disorder can be introduced in a controlled way. For x = 0, the compound crystallizes in the orthorhombic space group Pnma (D 16 2h ) with lattice constants a = 6.862 Å, b = 13.178 Å, and c = 6.897 Å.…”

Nuclear magnetic resonance in high magnetic field: Application to condensed matter physics

“…The purpose of this paper is to show how important is the magnetic field in the physics of QSS, and to concentrate on their microscopic properties and low-energy excitations. Several techniques like neutron scattering [62], EPR [63], and NMR [16] can give access to the microscopic properties of these new states, the most powerful being neutron scattering. This technique is however presently limited to magnetic fields lower than 17 T, even though inelastic neutron scattering experiments up to 27 T should become available soon [8].…”
