20.500.12556/RUL-175245 Chiral eigenbases of the XX and XY quantum spin chains We calculate the values of observables in chiral eigenstates of the XX quantum spin chain that were introduced in previous work and compare the form of the result with the respective expressions obtained in the more familiar eigenbasis of states with fixed magnetization in the z direction. We carry out the diagonalization of the XY spin chain in the chiral basis. We calculate the norm of the chiral XY eigenstates, and the values of the one-point functions and some neighbor two-point correlation functions. We interpret the spectrum and the particle content of the XY chain in terms of scattering states of an even number of kink and antikink excitations that are created over a reduced Brillouin zone. quantum mechanics quantum spin chains magnetism kvantna mehanika kvantne spinske verige magnetizem true false true Angleški jezik Slovenski jezik Članek v reviji 2025-10-22 16:41:56 2025-10-22 16:41:56 2025-12-07 04:04:41 0000-00-00 00:00:00 2025 0 0 Str. 094437-1-094437-15 iss. 9 Vol. 111 2025 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 530.145 2469-9950 10.1103/PhysRevB.111.094437 254360067 2411.17877v2.pdf 2411.17877v2.pdf 1 48A759BC4E2F922E714D4403313C28C0 b6898a61d5ba738ec054ce8915b64b443d02499a3b9ffebe0624485af4bbb1e7 b902c45c-af55-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=220592 https://journals.aps.org/prb/abstract/10.1103/PhysRevB.111.094437 0 c0749ee6-af55-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=220593 Fakulteta za matematiko in fiziko 0 0 0
