Noncollinear spin textures and 90° domain walls in twisted XY magnets
Guanghui Cheng, Shiva T. Konakanchi, Andres E. Llacsahuanga Allcca +8
Twisted moiré magnets are promising in exploring noncollinear magnetic phases, yet current experimental studies have been restricted to uniaxial magnets, limiting the accessible ph…
Octupole-driven spin torque switching of antiferromagnetic tunnel junctions
Jaimin Kang, Mohammad Hamdi, Shun Kong Cheung +28
Magnetic tunnel junctions (MTJs) based on ferromagnets are canonical devices in spintronics, with wide-ranging applications in data storage, computing, and sensing. They simultaneo…
Emergent Synaptic Plasticity from Tunable Dynamics of Probabilistic Bits
Sagnik Banerjee, Shiva T. Konakanchi, Supriyo Datta +1
Probabilistic (p-) computing, which leverages the stochasticity of its building blocks (p-bits) to solve a variety of computationally hard problems, has recently emerged as a promi…
Electrically Tunable Picosecond-scale Octupole Fluctuations in Chiral Antiferromagnets
Shiva T. Konakanchi, Sagnik Banerjee, Mohammad M. Rahman +4
We present a theory for the relaxation time of the octupole order parameter in nanoscale chiral antiferromagnets (AFMs) coupled to thermal baths and spin injection sources. Using s…
Discovery of a high-temperature antiferromagnetic state and transport signatures of exchange interactions in a Bi2Se3/EuSe heterostructure
Ying Wang, Valeria Lauter, Olga Maximova +10
Spatial confinement of electronic topological surface states (TSS) in topological insulators poses a formidable challenge because TSS are protected by time-reversal symmetry. In pr…
A Platform for Braiding Majorana Modes with Magnetic Skyrmions
Shiva T. Konakanchi, Jukka I. Väyrynen, Yong P. Chen +2
After a decade of intense theoretical and experimental efforts, demonstrating braiding of Majorana modes remains an unsolved problem in condensed matter physics due to platform spe…
