Advanced Electronic Materials, EarlyView.A very high electron concentration film has been achieved through Si doping on (100)‐oriented Ga2O3 substrates. A comprehensive study of Si doping effects on the electronic structure of Ga2O3 epitaxial thin films is performed using synchrotron‐based hard X‐ray photoemission spectroscopy (HAXPES).

Foliation-Based Approach to Quantum Gravity and Applications to Astrophysics
Universe, 2019 The recently proposed holography-inspired approach to quantum gravity is reviewed and expanded. The approach is based on the foliation of the background spacetime and reduction of the offshell states to the physical states.

The analytic renormalization group
Nuclear Physics B, 2016 Finite temperature Euclidean two-point functions in quantum mechanics or quantum field theory are characterized by a discrete set of Fourier coefficients $G_{k}$, $k\in\mathbb Z$, associated with the Matsubara frequencies $ _{k}=2 k/ $. We show that analyticity implies that the coefficients $G_{k}$ must satisfy an infinite number of model ...

Advanced Energy Materials, EarlyView.Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

Fractional Laplasians and propagation of waves in three-dimensional space as quantum process
Физика волновых процессов и радиотехнические системы, 2016 In this paper it is shown that in the whole range of problems of waves propagation there is hidden feynmanon. We call by feynmanon the quantum object moving along fractal trajectories in phase space of dynamical system related with wave equation ...

RENORMALIZATION WITHOUT INFINITIES [PDF]
International Journal of Modern Physics A, 2005 Most renormalizable quantum field theories can be rephrased in terms of Feynman diagrams that only contain dressed irreducible 2-, 3-, and 4-point vertices. These irreducible vertices in turn can be solved from equations that also only contain dressed irreducible vertices. The diagrams and equations that one ends up with do not contain any ultraviolet

Suppressed Thermal Conductivity in van der Waals Semiconductor SnS2 by Stacking Engineering
Advanced Energy and Sustainability Research, EarlyView.Achieving low thermal conductivity is crucial for materials used for thermoelectric energy conversion. It is demonstrated that the lattice thermal conductivity of van der Waals semiconductor SnS2 can be significantly reduced by introducing 2H and 4H structures stacked along the c‐axis.
