Entropy and Quantum Gravity [PDF]
Entropy, 2015 We give a review, in the style of an essay, of the author’s 1998 matter-gravity entanglement hypothesis which, unlike the standard approach to entropy based on coarse-graining, offers a definition for the entropy of a closed system as a real and objective quantity.

Water‐Wave Pancharatnam‐Berry Phase Induced by 4D Spin‐Orbit State Evolution
Advanced Science, EarlyView.The first observation of the Pancharatnam‐Berry (PB) phase in water waves is reported, revealing its extraordinary properties including unbounded phase values, spin‐momentum‐locked unidirectional channels, and a Poincaré hypersphere representation. These findings demonstrate the universality of the PB phase across different wave systems and in higher ...

Dynamics of Fricke–Painlevé VI Surfaces
DynamicsThe symmetries of a Riemann surface Σ∖{ai} with n punctures ai are encoded in its fundamental group π1(Σ). Further structure may be described through representations (homomorphisms) of π1 over a Lie group G as globalized by the character variety C=Hom(π1,

Ultrasensitive Diamond Cantilever‐Based Optical Microphone
Advanced Science, EarlyView.The first demonstration that high quality diamond cantilevers function as high‐sensitivity acoustic transducers is reported, combining CVD diamond cantilevers and an extrinsic Fabry‐Perot optical configuration. High transduction efficiency yields record sensitivity (51.5 VPa−1) and MDP (0.018 µPa/Hz$\rm {\sqrt {Hz}}$), enabling durable, low‐noise ...

Scrambling‐Enhanced Quantum Battery Charging in Black Hole Analogues
Advanced Science, EarlyView.By employing a black‐hole‐analog quantum battery constructed from a position‐dependent XY model, its dynamical behavior is investigated through a quench of the scrambling parameter. It is systematically quantified that how the simulated scrambling improves key performance metrics‐namely, stored energy, peak power, and charging time‐thereby offering a ...

Journal of High Energy PhysicsWe explore the relationship between complexity and duality in quantum systems, focusing on how local and non-local operators evolve under time evolution. We find that non-local operators, which are dual to local operators under specific mappings, exhibit
