We show how some physics behind black holes, simple clocks, simple computers, and the holographic principle is related to Planck-scale physics. We also discuss a formulation of the Dirac equation as a difference equation on a discrete Planck-scale spacetime lattice, and a possible interplay ...

We present an explicit reconstruction of the interior of an AdS2 black hole in Jackiw-Teitelboim gravity, that is entirely formulated in the dual SYK model
Recent simulations of two black holes colliding at close to the speed of light have shed light on the enigmatic physics behind what has been called by one astrophysicist as “one of the most violent events you can imagine in the universe.” “It’s a bit of a crazy thing ...
The Invisible Universe has chapters dedicated to all of these phenomena, describing them vividly while explaining the physics behind them in an accessible manner. Bothwell approaches each chapter like a detective story: he introduces some unexpected observation, follows the development of theories to ...
If the thermodynamic quantity, such as heat, has a fluctuation theorem31, do we also have a fluctuation theorem behind the spread of information? We answer this question affirmatively. First, we set some notations. Denote the probability distribution of the correlated state ρSR as pl, given ...
Our work presents a first step towards better understanding the physics behind the holomorphic twist and opens a window into making progress on a variety of fronts. The first direction to make progress lies in better understanding the L_\infty structure of the modes and its representation theory....
The intention behind our general, axiomatic framework is to prove irreversibility in as broad a setting as possible. The key strength of this approach is that irreversibility under the class of NE transformations enforces irreversibility under any smaller class of processes, which includes the vast ...
We explore the evolution with redshift of the rest-frame colours and space densities of active galactic nuclei (AGN) hosts (relative to normal galaxies) to shed light on the dominant mechanism that triggers accretion on to supermassive black holes as a function of cosmic time. Data from ...
We exploit a Hopf algebra structure behind the Magnus expansion to develop a fast algorithm which can compute the tree coefficients up to the 12th order (over half a million trees) in less than an hour. In a relativistic setting, our methods can be applied to the post-Minkowskian (PM) ...
