Equatorial magnetoplasma waves
Cooper Finnigan, Mehdi Kargarian, Dmitry K. Efimkin
Due to its rotation, Earth traps a few equatorial ocean and atmospheric waves, including Kelvin, Yanai, Rossby, and Poincare modes. It has been recently demonstrated that the mathe…
Hybrid topological magnon-phonon modes in honeycomb and kagome lattices
Bahman Sheikhi, Mehdi Kargarian, Abdollah Langari
Magnons and phonons are two fundamental neutral excitations of magnetically ordered materials which can significantly dominate the low-energy thermal properties. In this work we st…
Topological spin-plasma waves
Dmitry K. Efimkin, Mehdi Kargarian
The surface of a topological insulator hosts Dirac electronic states with the spin-momentum locking, which constrains spin orientation perpendicular to electron momentum. As a resu…
Excitonic insulator phase and dynamics of condensate in a topological one-dimensional model
Zahra Khatibi, Roya Ahemeh, Mehdi Kargarian
We employ mean-field approximation to investigate the interplay between the nontrivial band topology and the formation of excitonic insulator (EI) in a one-dimensional chain of ato…
Effects of dynamical noises on Majorana bound states
Roya Radgohar, Mehdi Kargarian
The nonlocal nature of unpaired Majorana bound states (MBSs) in topological superconductors can be exploited to create topologically protected qubits and perform gate operations fa…
Phase diagram and thermal Hall conductivity of spin-liquid Kekulé-Kitaev model
Fatemeh Mirmojarabian, Mehdi Kargarian, Abdollah Langari
In this work we study the phase diagram of Kekulé-Kitaev model. The model is defined on a honeycomb lattice with bond dependent anisotropic exchange interactions making it exactly…
