Directional strain control of magnetism in MnBiSe, MnSbSe, and MnSbTe freestanding monolayers
Swarnava Ghosh, Tanvir Sohail, Markus Eisenbach
MnBiSe, MnSbSe, and MnSbTe are layered magnetic quantum materials of interest for spintronic and topological electronic applications, where control of magnet…
Mechanism of charge transfer and electrostatic field fluctuations in complex metallic alloys
Wai-Ga D. Ho, Wasim Raja Mondal, Swarnava Ghosh +6
Complex metallic alloys exhibit rich disorder-driven electronic, magnetic, and vibrational behavior arising from strong chemical disorder, leading to unconventional structure-prope…
Edge Dislocation Mediated Anomalous Charge Transfer in Face Centered Cubic High Entropy Alloys
Gautam Anand, Swarnava Ghosh, Suman Chabri +1
Charge transfer in concentrated alloys governs their structural stability and functional response, and can be strongly perturbed by lattice defects. In high-entropy alloys, the int…
Optimizing Density Functional Theory for Strain-Dependent Magnetic Properties of Monolayer MnBiTe with Diffusion Monte Carlo
Jeonghwan Ahn, Swarnava Ghosh, Seoung-Hun Kang +6
Monolayer MnBiTe (MBT) is an intrinsically magnetic topological insulator whose magnetic response is strongly affected by strain and electron correlation. In density fu…
Quantum solver for single-impurity Anderson models with particle-hole symmetry
Mariia Karabin, Tanvir Sohail, Dmytro Bykov +8
Quantum embedding methods, such as dynamical mean-field theory (DMFT), provide a powerful framework for investigating strongly correlated materials. A central computational bottlen…
