Webthe spin and position of particles, which leads to the separability of these coordinates and the property that the w.f. can be written as a product of a spin and a spatial part: (r)˜(s). It follows, then, that the requirement that fermions occupy antisymmetric w.f.’s refers to this product of the spatial and spin parts.

WebMar 26, 2024 · We investigate a quantum many-body lattice system of one-dimensional spinless fermions interacting with a dynamical ${Z}_{2}$ gauge field. The gauge field mediates long-range attraction between fermions resulting in their confinement into bosonic dimers. At strong coupling we develop an exactly solvable effective theory of such dimers … WebApr 21, 2005 · Title: Deconfined Quantum Criticality at the Quantum Phase Transition from Antiferromagnetism to Algebraic Spin Liquid
WebJan 29, 2024 · On the other hand, let we have a fermionic model H f = ∑ i L − 1 c i † c i + 1. For spinless fermions, one can represent creation operator c i † and annihilation operator c i in matrix form as c i † = [ 0 1 0 0] and c i = [ 0 0 1 0]. So if we can write fermionic operators … WebIn particular, intriguing quantum phases emerge due to the coupling of the orbital degree of freedom to the charge, spin, or lattice degrees of freedom Kugel1982 ; Khaliullin2005 .
