General Relativity in IIB matrix model

Journal of High Energy Physics
The matrix models are non-perturbative formulations of string theory, from which many believe that spacetime arises. The matrix fluctuations around the spacetime thus created should represent both matter and gravitational fields.

M(atrix) theory: matrix quantum mechanics as a fundamental theory [PDF]

Reviews of Modern Physics, 2001
A self-contained review is given of the matrix model of M-theory. The introductory part of the review is intended to be accessible to the general reader. M-theory is an eleven-dimensional quantum theory of gravity which is believed to underlie all superstring theories.

Critical dimensions and small cycle dominance from all-orders asymptotics of d-matrix theory

Journal of High Energy Physics
Supersymmetric sectors of N $$ \mathcal{N} $$ = 4 super-Yang-Mills theory motivate the study of the partition function for the counting of gauge-invariant functions of d = 2, 3 matrices transforming under the adjoint action of U (N).

A supersymmetric SYK model with a curious low energy behavior

Journal of High Energy Physics
We consider N $$ \mathcal{N} $$ = 2, 4 supersymmetric SYK models that have a peculiar low energy behavior, with the entropy going like S = S 0 + (constant)T a , where a ≠ 1.

The effects of anti-vaccine conspiracy theories on vaccination intentions [PDF]

, 2014
The current studies investigated the potential impact of anti-vaccine conspiracy beliefs, and exposure to anti-vaccine conspiracy theories, on vaccination intentions. In Study 1, British parents completed a questionnaire measuring beliefs in anti-vaccine

A note on M(atrix) theory in seven dimensions with eight supercharges

, 1997
We consider M(atrix) theory compactifications to seven dimensions with eight unbroken supersymmetries. We conjecture that both M(atrix) theory on K3 and heterotic M(atrix) theory on T"3 are described by the same 5+1 dimensional theory with N = 2 ...

The companion equations and the moyal-nahm equations [PDF]

, 2000
The first part of this thesis is concerned with the companion equations. These are equations of motion for the companion Lagrangian which is proposed to be the Lagrangian for a field theory associated with strings and branes, similar to the Klein-Gordon ...

Quantum mechanics on a noncommutative brane in M(atrix) theory [PDF]

Physics Letters B, 2001
We consider the quantum mechanics of a particle on a noncommutative two-sphere with the coordinates obeying an SU(2)-algebra. The momentum operator can be constructed in terms of an $SU(2)\times SU(2)$-extension and the Heisenberg algebra recovered in the smooth manifold limit. Similar considerations apply to the more general SU(n) case.

Beyond Eikonal Scattering in M(atrix)-Theory [PDF]

We study the problem of more general kinematics for the finite N M(atrix)-Model than the simple straight line motion that has been used before. This is supposed to be related to momentum transferring processes in the dual super-gravity description.
