Relaxation approach to quantum-mechanical modeling of ferroelectric and antiferroelectric phase transitions

Nikhilesh Maity, Sergey Lisenkov, Arlies Valdespino +5

Ferroelectrics and antiferroelectrics are the electric counterparts of ferromagnets and antiferromagnets. These materials undergo temperature- and electric-fieldinduced phase trans…

Giant Spin Splitting and its Origin in Methylhydrazinium Lead Halide Perovskites

Nikhilesh Maity, Ravi Kashikar, S. Lisenkov +1

Spin splitting, or removal of spin degeneracy in the electronic energy band/level is often a measure of spin-orbit coupling strength and a way to manipulate spin degrees of freedom…

Ferroelectricity at the extreme thickness limit in the archetypal antiferroelectric PbZrO

Nikhilesh Maity, Milan Haddad, Nazanin Bassiri-Gharb +4

Size-driven transition of an antiferroelectric into a polar ferroelectric or ferrielectric state is a strongly debated issue from both experimental and theoretical perspectives. Wh…

Coupling of structure and magnetism to spin splitting in hybrid organic-inorganic perovskites

Ravi Kashikar, D. DeTellem, P. S. Ghosh +6

Hybrid organic-inorganic perovskites are famous for the diversity of their chemical compositions, phases and phase transitions, and associated physical properties. We use a combina…
