From the very beginning quantum statistical mechanics can be formulated in terms of a thermodynamic potential, which has the electron density as the basic variable. By employing a well-known procedure in quantum statistical mechanics for the construction of stationarity principles [T. D. Lee and C. N. Yang, Phys. Rev. 113, 1165 (1959); 117, 22 (1960)], the variational principles of Hohenberg, Kohn [P. Hohenberg and W. Kohn, Phys. Rev. B 136, 864 (1964)], and Mermin [N. D. Mermin, Phys. Rev. A… Expand
Scaling, bounds, and inequalities for the noninteracting density functionals at finite temperature
Finite-temperature density functional theory requires representations for the internal energy, entropy, and free energy as functionals of the local density field. A central formal difficulty for anExpand

TLDR
The basic physico-chemical concepts of density functional theory are employed to highlight the energy role in chemical structure while its extended influence in electronic localization function helps in chemical bonding understanding. Expand
Density Functional Theory: From Conceptual Level Toward Practical Functionality
Density Functional Theory (DFT), the most productive and attractive method of computational chemistry in the last decades, a beacon expected to endure for a long time, is discussed in this chapter inExpand
First-principles calculations of Co7W6 doped with Re: Site occupancy and electronic properties
Abstract Using the first-principles calculations based on the density functional theory, we studied the site occupancy of Re in the Co7W6 μ phase and its effects on the electronic properties. TheExpand

TLDR
The pressure-induced phase transitions of bromine chloride (BrCl) were studied using the CALYPSO structure prediction method and first-principles calculations to find the high-pressure P4/mmm - BrCl phase, which is predicted to exist in BrCl compounds for the first time. Expand
