Quantum coherent dynamics of quasiclassical spacetimes
Sijia Wang, Achintya Sajeendran, Dong-han Yeom +2
In a wide range of quantum gravity theories, quasiclassical geometries, which are solutions to the Einstein field equations approximately, are described by "coherent states." Here…
Quantum signatures of proper time in optical ion clocks
Gabriel Sorci, Joshua Foo, Dietrich Leibfried +2
Optical clocks based on atoms and ions probe relativistic effects with unprecedented sensitivity by resolving time dilation due to atom motion or different positions in the gravita…
Quantum metasurfaces as probes of vacuum particle content
Germain Tobar, Joshua Foo, Sofia Qvarfort +3
The quantum vacuum of the electromagnetic field is inherently entangled across distinct spatial sub-regions, resulting in entangled particle content across these sub-regions. Howev…
General relativistic particle trajectories via quantum mechanical weak values and the Schwarzschild-Alcubierre spacetime
Joshua Foo, Cameron Bellamy, Timothy C. Ralph
We show that the average trajectories of relativistic quantum particles in Schwarzschild spacetime, obtained via quantum mechanical weak measurements of momentum and energy, are eq…
Witnessing mass-energy equivalence with trapped atom interferometers
Jerzy Paczos, Joshua Foo, Magdalena Zych
We propose an experimental setup to probe the interplay between the quantum superposition principle and gravitational time dilation arising from the mass-energy equivalence. It cap…
Signatures of Rotating Black Holes in Quantum Superposition
Cendikiawan Suryaatmadja, Cemile Senem Arabaci, Matthew P. G. Robbins +3
A new approach for operationally studying the effects of spacetime in quantum superpositions of semiclassical states has recently been proposed by some of the authors. This approac…
