Fast Thermoelectric Responses from Unconventional Na‐I Stoichiometry in Reduced Graphene Oxide Films
Advanced Science, EarlyView.By coating the graphene oxide suspension and the dilute NaI solution layer‐by‐layer from bottom up, this work achieves a heterogeneous structure from asymmetry of the up and bottom surface Na and I atomic ratios in reduced graphene oxide (rGO) films, which exhibits fast thermoelectric responses.

Experimental Joint Estimation of Phase and Phase Diffusion Via Deterministic Bell Measurements
Advanced Science, EarlyView.This work employs Bell measurement, a form of entangling measurement, to estimate both the phase and its fluctuations in an optical interferometer. By incorporating a novel quantum effect at the measurement stage, the proposed method achieves the ultimate precision limit and demonstrates the significant potential of entangling measurements in multi ...

Five-point superluminality bounds
Journal of High Energy PhysicsWe investigate how the speed of propagation of physical excitations is encoded in the coefficients of five-point interactions. This leads to a superluminality bound on scalar five-point interactions, which we present here for the first time.

Quantum Gravity: Has Spacetime Quantum Properties? [PDF]
, 2009 The incompatibility between GR and QM is generally seen as a sufficient motivation for the development of a theory of Quantum Gravity. If - so a typical argumentation - QM gives a universally valid basis for the description of all natural systems, then ...

Noether Symmetries and Covariant Conservation Laws in Classical, Relativistic and Quantum Physics
, 2010 We review the Lagrangian formulation of Noether symmetries (as well as "generalized Noether symmetries") in the framework of Calculus of Variations in Jet Bundles, with a special attention to so-called "Natural Theories" and "Gauge-Natural Theories ...

Advanced Science, EarlyView.An ionic liquid‐based shear‐thickening fluid (ILSTF) exhibits lubricated dynamics from strong shear thickening to impact‐triggered jamming. A persistent nanometric solvation layer around silica governs both the shear thickening saturation in rheology and jamming front propagation under dynamic impact compression.

Principle of least decoherence for Newtonian semi-classical gravity
, 2017 Recent works have proved that semi-classical theories of gravity needed not be fundamentally inconsistent, at least in the Newtonian regime. Using the machinery of continuous measurement theory and feedback, it was shown that one could construct well ...

Graph‐Theory Approach to Element Miscibility and Alloy Design
Advanced Science, EarlyView.Graph and network theory enables pathway toward complex multiscale interactions between different elements for alloy design or interface engineering. Utilizing element's inherent properties and preferential interactivity, favorable mixed material formation, solubility and miscibility can be predicted.
