A Universal Crystal-Field Design Principle for Orbital-Order-Driven Altermagnetism
Shantanu Pathak, Saswata Bhattacharya
The paper proposes a universal crystal‑field design principle that predicts and explains orbital‑order‑driven altermagnetism across transition‑metal compounds, showing how structur…
Lone-Pair-Induced Lattice Softness Enables Ultralow Thermal Conductivity in Hybrid Organic-Inorganic Perovskite GuaPbI
Rudra P. Singh, Shantanu Pathak, Saswata Bhattacharya +1
Thermal conductivity () minimization of inorganic thermoelectrics can only be achieved to a certain extent via nanostructural engineering. Here, we introduce a lone-pair-driven…
Tunable Carrier Dynamics in Carbide Antiperovskites via A-Site Cation Substitution
Sanchi Monga, Saswata Bhattacharya
We present a comprehensive first-principles investigation of the electronic structure and excited-state carrier dynamics in the carbide antiperovskites CaCSe and SrCSe$…
Tuning Nonradiative Recombination via Cation Substitution in Inorganic Antiperovskite Nitrides
Sanchi Monga, Saswata Bhattacharya
Inorganic antiperovskite nitrides have recently emerged as promising materials for photovoltaic applications, yet their nonradiative recombination dynamics remain largely unexplore…
Strain- and Field-Tunable Nonrelativistic Spin Splitting and Wave-Symmetry-Dependent Spin Transport in Twisted Bilayer Altermagnets
Shantanu Pathak, Saswata Bhattacharya
Magnetism-driven nonrelativistic spin splitting (NRSS) provides a pathway toward efficient, spin-orbit-free spintronics. In centrosymmetric two-dimensional antiferromagnets, spin-p…
Ferroelectric Control of Spin Textures in Layered Hybrid Perovskites
Divyanshi Tyagi, Saswata Bhattacharya
Hybrid organic--inorganic perovskites with broken inversion symmetry provide a fertile ground for uncovering coupled spin-orbit and ferroelectric phenomena. Here, we investigate th…
