Generalized Nested Summation of Powers of Natural Numbers
Patibandla Chanakya, Putla Harsha
In this paper, we provide a general framework for obtaining the formula for nested summation of powers of natural numbers. We define a special triangular array of numbers from whic…
Enhanced Seebeck effect in graphene devices by strain and doping engineering
Mai Chung Nguyen, Viet Hung Nguyen, Huy-Viet Nguyen +2
In this work, we investigate the possibility of enhancing the thermoelectric power (Seebeck coefficient) in graphene devices by strain and doping engineering. While a local strain…
Van der Waals Coefficients of Atoms and Molecules from a Simple Approximation for the Polarizability
Huy-Viet Nguyen, Stefano de Gironcoli
A simple and computationally efficient scheme to calculate approximate imaginary-frequency dependent polarizability, hence asymptotic van der Waals coefficient, within density func…
Efficient and accurate calculation of exact exchange and RPA correlation energies in the Adiabatic-Connection Fluctuation-Dissipation theory
Huy-Viet Nguyen, Stefano de Gironcoli
Recently there has been a renewed interest in the calculation of exact-exchange and RPA correlation energies for realistic systems. These quantities are main ingredients of the so-…
