Transmission across non-Hermitian -symmetric quantum dots and ladders
Abhiram Soori, M. Sivakumar, V. Subrahmanyam
A non-Hermitian region connected to semi-infinite Hermitian lattices acts either as a source or as a sink and the probability current is not conserved in a scattering typically. Ev…

Slow dynamics of interacting antiferromagnetic nanoparticles
Sunil Kumar Mishra, V. Subrahmanyam
We study magnetic relaxation dynamics, memory and aging effects in interacting polydisperse antiferromagnetic NiO nanoparticles by solving a master equation using a two-state model…

Size-dependent magnetization fluctuations in NiO nanoparticles
Sunil Kumar Mishra, V. Subrahmanyam
The finite size and surface roughness effects on the magnetization of NiO nanoparticles is investigated. A large magnetic moment arises for an antiferromagnetic nanoparticle due to…
