Matter relative to quantum hypersurfaces
Philipp A. Hoehn, Andrea Russo, Alexander R. H. Smith
We explore the canonical description of a scalar field as a parameterized field theory on an extended phase space that includes additional embedding fields that characterize spacet…
The weak field limit of quantum matter back-reacting on classical spacetime
Isaac Layton, Jonathan Oppenheim, Andrea Russo +1
Consistent coupling of quantum and classical degrees of freedom exists so long as there is both diffusion of the classical degrees of freedom and decoherence of the quantum system.…
Computing spacetime
Juan F. Pedraza, Andrea Russo, Andrew Svesko +1
Inspired by the universality of computation, we advocate for a principle of spacetime complexity, where gravity arises as a consequence of spacetime optimizing the computational co…
Sewing spacetime with Lorentzian threads: complexity and the emergence of time in quantum gravity
Juan F. Pedraza, Andrea Russo, Andrew Svesko +1
Holographic entanglement entropy was recently recast in terms of Riemannian flows or 'bit threads'. We consider the Lorentzian analog to reformulate the 'complexity=volume' conject…
Lorentzian threads as 'gatelines' and holographic complexity
Juan F. Pedraza, Andrea Russo, Andrew Svesko +1
The continuous min flow-max cut principle is used to reformulate the 'complexity=volume' conjecture using Lorentzian flows -- divergenceless norm-bounded timelike vector fields who…
The Second Law of Quantum Complexity and the Entanglement Wormhole
Andrea Russo
This work is originally a Cambridge Part III essay paper. Quantum complexity arises as an alternative measure to the Fubini metric between two quantum states. Given two states and…
