We define and calculate versions of complexity for free fermionic quantum field theories in
1+ 1 and 3+ 1 dimensions, adopting Nielsen's geodesic perspective in the space of circuits …

A bstract We analyse the dynamics of near-extremal Reissner-Nordström black holes in
asymptotically four-dimensional Anti de Sitter space (AdS 4). We work in the spherically …

The first part of these lecture notes is mostly devoted to a comparative discussion of the
three basic large $ N $ limits, which apply to fields which are vectors, matrices, or tensors of …

A bstract The eigenstate thermalization hypothesis (ETH) explains how closed unitary
quantum systems can exhibit thermal behavior in pure states. In this work we examine a …

We study the operators in the large N tensor models, focusing mostly on the fermionic
quantum mechanics with O (N) 3 symmetry which may be either global or gauged. In the …

A bstract We consider different sets of AdS 2 boundary conditions for the Jackiw-Teitelboim
model in the linear dilaton sector where the dilaton is allowed to fluctuate to leading order at …

A bstract We study the behaviour of extremal and near-extremal black holes at low energies
and low temperatures and find that it can be understood from the near-horizon AdS 2 region …

A bstract We show that the free energy at low temperatures for near-extremal black holes is
correctly obtained from the Jackiw-Teitelboim (JT) model of gravity. Our arguments apply to …

A bstract It has recently been demonstrated that the large N limit of a model of fermions
charged under the global/gauge symmetry group O (N) q− 1 agrees with the large N limit of …

We provide the first steps toward a flat space holographic correspondence in two bulk
spacetime dimensions. The gravity side is described by a conformally transformed version of …
