When electrons meet ferroelastic domain walls in Strontium Titanate
Shashank Kumar Ojha, Jyotirmay Maity, Srimanta Middey
Strontium titanate (SrTiO), famously described by Nobel laureate K. A. Müller as the "drosophila of solid-state physics", has been extensively investigated over the last sevent…
Beyond being free: glassy dynamics of SrTiO-based two-dimensional electron gas
Jyotirmay Maity, Shashank Kumar Ojha, Prithwijit Mandal +5
Electron glasses offer a convenient laboratory platform to study glassy dynamics. Traditionally, the interplay between long-range Coulomb interactions and disorder is deemed instru…
Orthorhombic distortion drives orbital ordering in an antiferromagnetic 3 Mott insulator
Prithwijit Mandal, Shashank Kumar Ojha, Duo Wang +9
The orbital, which represents the shape of the electron cloud, very often strongly influences the manifestation of various exotic phenomena, e.g., magnetism, metal-insulator transi…
Quantum fluctuations lead to glassy electron dynamics in the good metal regime of electron doped KTaO3
Shashank Kumar Ojha, Sankalpa Hazra, Surajit Bera +10
One of the central challenges in condensed matter physics is to comprehend systems that have strong disorder and strong interactions. In the strongly localized regime, their subtle…
Hole doping in a negative charge transfer insulator
Ranjan Kumar Patel, Krishnendu Patra, Shashank Kumar Ojha +7
NiO is a negative charge transfer energy system and exhibits a temperature-driven metal-insulator transition (MIT), which is also accompanied by a bond disproportionation (…
Spin liquid behavior of a three-dimensional magnetic system BaNiIrO with = 1
Siddharth Kumar, S. K. Panda, Manju Mishra Patidar +7
The quantum spin liquid (QSL) is an exotic phase of magnetic materials where the spins continue to fluctuate without any symmetry breaking down to zero temperature. Among the handf…
Epitaxial stabilization of ultra thin films of high entropy perovskite
Ranjan Kumar Patel, Shashank Kumar Ojha, Siddharth Kumar +4
High entropy oxides (HEOs) are a class of materials, containing equimolar portions of five or more transition metal and/or rare-earth elements. We report here about the layer-by-la…
Anomalous electron transport in epitaxial NdNiO films
Shashank Kumar Ojha, Sujay Ray, Tanmoy Das +8
The origin of simultaneous electronic, structural and magnetic transitions in bulk rare-earth nickelates (NiO) remains puzzling with multiple conflicting reports on the nat…
Epitaxial strain modulated electronic properties of interface controlled nickelate superlattice
S. Middey, D. Meyers, Shashank Kumar Ojha +5
Perovskite nickelate heterostructure consisting of single unit cell of EuNiO and LaNiO have been grown on a set of single crystalline substrates by pulsed laser interval de…
