Time uncertainty and fundamental sensitivity limits in quantum sensing: application to optomechanical gravimetry
Salman Sajad Wani, Saif Al-Kuwari, Arshid Shabir +3
High-sensitivity accelerometers and gravimeters, achieving the ultimate limits of measurement sensitivity are key tools for advancing both fundamental and applied physics. While nu…
Undecidability in Spacetime Geometry via the AdS/CFT Correspondence
Sameer Ahmad Mir, Francesco Marino, Arshid Shabir +2
Undecidability, a hallmark of Gödel incompleteness theorems, has recently emerged in quantum many-body physics through the spectral gap problem. We demonstrate how this logical li…
Can quantum gravity be both consistent and complete?
Mir Faizal, Lawrence M. Krauss, Arshid Shabir +2
General relativity, despite its profound successes, fails as a complete theory due to presence of singularities. While it is widely believed that quantum gravity has the potential…
Universal work statistics in quenched gapless quantum systems
Donny Dwiputra, Mir Faizal, Francesco Marino +1
We study the universality of work statistics performed during a quench in gapless quantum systems. We show that the cumulants of work scale separately in the fast and slow quench r…
Consequences of Undecidability in Physics on the Theory of Everything
Mir Faizal, Lawrence M. Krauss, Arshid Shabir +1
General relativity treats spacetime as dynamical and exhibits its breakdown at singularities. This failure is interpreted as evidence that quantum gravity is not a theory formulate…
Listening to Quantum Gravity?
Lawrence M. Krauss, Francesco Marino, Samuel L. Braunstein +2
Recent experimental progresses in controlling classical and quantum fluids have made it possible to realize acoustic analogues of gravitational black holes, where a flowing fluid p…
