Topological Hall plateau in quasi-2D kagome magnet YMnSn
Sambit Jena, Nastaran Salehi, Manuel Pereiro Lopez +5
We examine the impact of the Dzyaloshinskii-Moriya interaction (DMI) in kagome magnets and show that a predominantly planar DMI together with ferromagnetic exchange stabilizes a di…
Selective Amplification of the Topological Hall Signal in CrTe: The Role of Molecular Exchange Coupling
Suman Mundlia, Ritesh Kumar, Anshika Mishra +3
Layered magnetic transition-metal chalcogenides (TMCs) are a focal point of research, revealing a variety of intriguing magnetic and topological ground states. Within this family o…
Interface controlled Berry phase and anisotropic spin-charge conversion in altermagnet-topological insulator bilayers
Juhi Singh, Narayan Mohanta
We propose an altermagnet-topological insulator bilayer as a platform to engineer Berry phase driven spin-charge responses using an interfacial buffer layer. Using a momentum-space…
Diode effect in a skyrmion-coupled high-temperature Josephson junction
Digvijay Singh, Pankaj Sharma, Narayan Mohanta
We show that a planar Josephson junction having -wave superconducting regions, with a skyrmion crystal placed underneath, produces a robust gate-tunable superconducting diode ef…
Multiple Majorana bound states and their resilience against disorder in planar Josephson junctions
Pankaj Sharma, Narayan Mohanta
Planar Josephson junctions are theoretically predicted to harbor zero-energy Majorana bound states (MBS) in a tunable two-dimensional geometry, at the two ends of the middle metall…
Magnetic field-free braiding and nontrivial fusion of Majorana bound states in high-temperature planar Josephson junctions
Pankaj Sharma, Narayan Mohanta
Demonstration of non-Abelian statistics of Majorana bound states (MBS) is crucial for the realization of fault-tolerant topological quantum computation. Two-dimensional platforms s…
