Flux quench in a system of interacting spinless fermions in one dimension [PDF]
, 2016 We study a quantum quench in a one-dimensional spinless fermion model (equivalent to the XXZ spin chain), where a magnetic flux is suddenly switched off.

High Step-up Coupled Inductor Inverters Based on qSBIs
Energies, 2019 In this paper, two types of high step-up coupled inductor inverters based on qSBIs (quasi- switched boost inverters) are proposed. By applying the coupled inductor to the qSBIs, the voltage gain of the proposed inverter is regulated by turn ratio and ...

Star formation in shocked cluster spirals and their tails [PDF]
, 2014 Recent observations of ram pressure stripped spiral galaxies in clusters revealed details of the stripping process, i.e., the truncation of all interstellar medium (ISM) phases and of star formation (SF) in the disk, and multiphase star-forming tails ...

Improved switched-inductor quasi-switched-boost inverter with low input current ripple
2015 56th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON), 2015 The quasi-switched-boost inverter is an alternative to the quasi-Z-Source inverter. Its passive component number is two times smaller but it contains two additional semiconductor components. Earlier the switched-inductor cell was applied in this topology to enhance dc voltage gain at the cost of high input current ripple.
