Design and Implementation of IGBT based Static Excitation System with Buck Converter [PDF]
2018 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2018 This paper presents the development of a DC-DC buck converter based static excitation system for a micro-alternator. The IGBT based AC to DC converter is used as Front End Converter (FEC) followed by a buck converter to control the field voltage of micro-alternator.

Optimal Dephasing for Ballistic Energy Transfer in Disordered Linear Chains
, 2017 We study the interplay between dephasing, disorder, and openness on transport efficiency in a one-dimensional chain of finite length $N$, and in particular the beneficial or detrimental effect of dephasing on transport.

Nonanalytic corrections to the specific heat of a three-dimensional Fermi liquid [PDF]
, 2005 We revisit the issue of the leading nonanalytic corrections to the temperature dependence of the specific heat coefficient, $\gamma (T)=C(T)/T,$ for a system of interacting fermions in three dimensions.
