A bstract Quiver quantum mechanics describes the low energy dynamics of a system of
wrapped D-branes. It captures several aspects of single and multicentered BPS black hole …

A bstract We study the various head-on collisions of two bunches of D0-branes and their real-
time evolution in the BFSS matrix model in classical limit. For a various matrix size N …

We study the smallest nontrivial matrix model that can be considered to be a (toy) model of a
black hole. The model consists of a pair of 2× 2 traceless Hermitian matrices with a …

We study the fuzzy spaces (as special examples of noncommutative manifolds) with their
quasicoherent states in order to find their pertinent metrics. We show that they are naturally …

A bstract We examine the 5d Yang-Mills matrix model in 0+ 1-dimensions with U (4N) gauge
symmetry and a mass deformation term. We determine the explicit SU (4)≈ SO (6) …

We present a toy model of a fuzzy Schwarzschild space slice (as a noncommutative
manifold), in which quantum mean values and quantum quasi-coherent states (states …

A bstract Matrix models play an important role in studies of quantum gravity, being
candidates for a formulation of M-theory, but are notoriously difficult to solve. In this work, we …

A bstract BMN Matrix theory admits vacua in the shape of large spherical membranes.
Perturbing around such vacua, the setup provides for a controlled computational framework …

A bstract Matrix quantum mechanics offers an attractive environment for discussing
gravitational holography, in which both sides of the holographic duality are well-defined …

Suppose—suppose—the end of the world is near, and whatever your fate may be—a
colossal comet, nuclear annihilation, a virulent virus—you have reconciled with the …
