Quantum Graph Theory by Example

Quantum graphs have been introduced by Duan, Severini, and Winter to describe the zero-error behaviour of quantum channels. Since then, quantum graph theory has become a field of study in its own right. A substantial source of difficulty in working with quantum graphs compared to...

Thermodynamic Description of Wealth Inequality in the World

According to the recent Wealth Thermalization Hypothesis (WTH), the wealth inequality in the world is described by the Rayleigh–Jeans (RJ) thermal distribution of interacting agents in a society with social stratification. In this concept, the wealth layers of society are associa...

Physics by Constraint: From Consistency Conditions to Physical Claims

Physics by Constraint: From Consistency Conditions to Physical Claims is a source-bound comparative study of how theoretical-physics programmes use consistency conditions and how bounded formal outputs connect to physical claims. "Physics by constraint" is descriptive vocabulary,...

Efficient quantum implementation of dynamical mean field theory for correlated materials

The accurate theoretical description of materials with strongly correlated electrons is a formidable challenge in condensed matter physics and computational chemistry. Dynamical Mean Field Theory (DMFT) is a successful approach that predicts behaviors of such systems by incorpora...
