Theory of valence-band and core-level photoemission from plutonium dioxide

Jindrich Kolorenc, Agnieszka L. Kozub, Alexander B. Shick

The correlated-band theory implemented as a combination of the local-density approximation with the dynamical mean-field theory is applied to PuO2. An insulating electronic structu…

Relativity of arithmetic as a fundamental symmetry of physics

Marek Czachor

Arithmetic operations can be defined in various ways, even if one assumes commutativity and associativity of addition and multiplication, and distributivity of multiplication with…

Analysis of an attenuator artifact in an experimental attack by Gunn-Allison-Abbott against the Kirchhoff-law-Johnson-noise (KLJN) secure key exchange system

Laszlo B. Kish, Zoltan Gingl, Robert Mingesz +3

A recent paper by Gunn-Allison-Abbott (GAA) [L.J. Gunn et al., Scientific Reports 4 (2014) 6461] argued that the Kirchhoff-law-Johnson-noise (KLJN) secure key exchange system could…

A Mathematica Program for heat source function of 1D heat equation reconstruction by three types of data

Tomasz M. Lapinski, Sergey Leble

We solve an inverse problem for the one-dimensional heat diffusion equation. We reconstruct the heat source function for the three types of data: 1) single position point and diffe…

Quantum randomness protected against detection loophole attacks

Piotr Mironowicz, Gustavo Cañas, Jaime Cariñe +6

Device and semi-device independent quantum randomness generators (DI- and SDI-QRNGs) are crucial for applications requiring private randomness. However, they are vulnerable to dete…

No quantum realization of extremal no-signaling boxes

Ravishankar Ramanathan, Jan Tuziemski, Michał Horodecki +1

Pure states are very important in any theory since they represent states of maximal information about the system within the theory. Here, we show that no non-trivial (not local rea…
