, 2014 We give a brief description of some compelling connections between general relativity and thermodynamics through i) the semi-classical tunnelling method(s) and ii) the field-theoretical modelling of Unruh-DeWitt detectors. In both approaches it is possible to interpret some quantities in a thermodynamical frame.

Electrocapillary Modulated Interfacial Tension Amplifies Liquid Metal Transduction
Advanced Functional Materials, EarlyView.This study presented an electrocapillary‐enhanced magnetohydrodynamic pumping strategy that harnesses the Lorentz force and interfacial tension modulation of liquid metal droplets to achieve amplified fluidic power. The system enabled low‐voltage, self‐oscillating fluidic transduction with enhanced pressure and flow generation, supporting compact ...

Advanced Functional Materials, EarlyView.Atomic layer deposition is used to conformally surface engineer polymeric membranes to fabricate inorganic–organic hybrid membranes. These membranes have exceptionally strong attraction toward water even in high oil containing emulsions, which leads to an extremely strong hydration layer at the interface.

Action and Entanglement in Gravity and Field Theory [PDF]
Physical Review Letters, 2013 In non-gravitational quantum field theory, the entanglement entropy across a surface depends on the short-distance regularization. Quantum gravity should not require such regularization, and it's been conjectured that the entanglement entropy there is always given by the black hole entropy formula evaluated on the entangling surface. We show that these
