Definitions and meanings of "Spinor"

What do we mean by spinor?

A mathematical object associated with group representations, often used in theoretical physics to model certain topological properties of space. Spinors resemble vectors but change sign (that is, they are multiplied by −1) when rotated 360 degrees. noun

An element of the fundamental representation of a Clifford algebra noun

As spinor is a variable which has algebraic properties identical to that of angular momentum or spin. ❋ Unknown (2009)

Now we consider the primary species of dark matter as the neutralino, which might be a Majorana spinor field and act as its own anti-matter. ❋ Unknown (2009)

As such the position spinor x is related to the momentum spinor p by a "motion," similar to x = x0 + vt. ❋ Unknown (2009)

I have ideas that the D-branes have spinor structure similar to electrons which constrain some of that structure in ways. ❋ Unknown (2009)

A twistor is a pair of spinors well what's a spinor? ❋ Unknown (2009)

For gravity I turn to the Weyl tensor C_ {abcd}, which is the traceless component of Riemann curvature tensor for spacetime, and in spinor form this may be written as ❋ Julianne (2008)

The spinor solutions of the Dirac equation have positive and negative solutions, just as the quadratic equation often has positive and negative solutions. ❋ Julianne (2008)

The mass which couples the two equations is due to the Higgs field with the Yukawa Lagrangian L = bar-psi H psi which in spinor components is ❋ Julianne (2008)

For non-zero outcomes these spinor wave equations are forms of the Dirac equation. ❋ Julianne (2008)

I also think that the 0-branes and their spinor field content define the spin networks of Smolin and the rest of the LQG mafia, where by the way some of their developments of late involve ribbons and stringy like things. ❋ Sean (2008)

But then you take the commutator of two covariant derivatives acting on this spinor field and get a relation involving the Riemann tensor. ❋ Mark (2008)

In this way there is in the path integral of possible configurations a combinatorial network of spinor fields, which is what is the “spin-foam” or causal net common to Lopp variable LQG. ❋ Sean (2008)

Being that the supersymmetry variation of the gravitino is the covariant derivative of the local spinor parameterizing the supersymmetry transformation, this would seem to always imply that the condition for supersymmetry is that there must exist a covariantly constant spinor field. ❋ Mark (2008)

It is a “space plus time” spinor theory of relativity which quantizes certain connection coefficients. ❋ Sean (2007)

It would seem at first sight that a lattice formulation could never reproduce this, since in finite volume (e.g. on the 4-torus) the space of lattice spinor fields is finite-dimensional but to have a non-trivial index theory the operators generally must be acting on an infinite-dimensional vectorspace. ❋ Sean (2007)

There are three 8 dimensional representations-the vector, spinor and conjugate spinor, related by a symmetry called triality that can be seen to underlie the structure of the supersymmetry algebras between 8 and 11 dimensions. ❋ Sean (2006)

If ψ is spinor-valued, the products in numerator and denominator should be understood as scalar products. ❋ Goldstein, Sheldon (2006)

Bohmian mechanics makes sense for particles with spin, i.e., for particles whose wave functions are spinor-valued. ❋ Goldstein, Sheldon (2006)

Unbroken target space supersymmetry means existence of a constant spinor. ❋ Mark (2005)

This is the case precisely if the solution has a Killing spinor that squares to a timelike vector. ❋ Mark (2005)
