Spins and spinless fermions
WebApr 21, 2005 · Title: Deconfined Quantum Criticality at the Quantum Phase Transition from Antiferromagnetism to Algebraic Spin Liquid WebIn particle physics, a boson (/ ˈ b oʊ z ɒ n / / ˈ b oʊ s ɒ n /) is a subatomic particle whose spin quantum number has an integer value (0, 1, 2, ...). Bosons form one of the two fundamental classes of subatomic particle, the other being fermions, which have odd half-integer spin (1 ⁄ 2, 3 ⁄ 2, 5 ⁄ 2, ...).Every observed subatomic particle is either a boson or a fermion.

WebAnswer (1 of 4): Sorry, by definition ‘fermions’ are particles with half-integer spins. So, they can not be spinless (or of spin zero). Spinless particles (with ... WebThe spinless anticommuting field shows that spinless fermions are nonrelativistically consistent. Likewise, the theory of a spinor commuting field shows that spinning bosons …
WebAs illustrated in the above picture, you can think of spin-1/2 fermions on a chain as spinless fermions living on a ladder (and analogous mappings for higher dimensional lattices). Each rung (a blue box in the picture) forms a SpinHalfFermionSite which is composed of two FermionSite (the circles in the picture) for spin-up and spin-down. The ...
