Understanding the ferromagnetic insulating state in Cr doped VO
Shishir Kumar Pandey, Abhinav Kumar, Sagar Sarkar +1
Experimentally Cr doping in the rutile phase of VO is found to stabilize a charge ordered ferromagnetic insulating state in the doping range of 10\% to 20\%. In this work, we i…
Prediction of low energy phase transition in metal doped MoTe from first principle calculations
Abhinav Kumar, Alejandro H. Strachan, Nicolas Onofrio
Metal-insulator transitions in two dimensional materials represent a great opportunity for fast, low energy and ultra-dense switching devices. Due to the small energy difference be…
Higgs-Axion interplay and anomalous magnetic phase diagram in TlCuCl
Gaurav Kumar Gupta, Kapildeb Dolui, Abhinav Kumar +2
What is so unique in TlCuCl3 which drives so many unique magnetic features in this compound? To study these properties, here we employ a combination of ab-initio band structure, ti…
Chemical exfoliation of MoS2 leads to semiconducting 1T' phase and not the metallic 1T phase
Banabir Pal, Anjali Singh, Sharada. G +8
A trigonal phase existing only as small patches on chemically exfoliated few layer, thermodynamically stable 1H phase of MoS2 is believed to influence critically properties of MoS2…
Room temperature dynamic correlation between methylammonium molecules in lead-iodine based perovskites: An ab-initio molecular dynamics perspective
Jonathan Lahnsteiner, Georg Kresse, Abhinav Kumar +3
The high efficiency of lead organo-metal-halide perovskite solar cells has raised many questions about the role of the methylammonium (MA) molecules in the Pb-I framework. Experime…
The sphere packing problem in dimension 24
Henry Cohn, Abhinav Kumar, Stephen D. Miller +2
Building on Viazovska's recent solution of the sphere packing problem in eight dimensions, we prove that the Leech lattice is the densest packing of congruent spheres in twenty-fou…
