Excitonic Magnetism in Ruthenium Pyrochlores
Swetlana Swarup, Yang Yang, Natalia B. Perkins
Strong spin-orbit coupling in systems is expected to stabilize a nonmagnetic singlet ground state, yet many ruthenium pyrochlores exhibit robust long-range magnetic ord…
Spin-lattice coupling induced chiral phonons and their signature in Raman Circular Dichroism
Eduard Koller, Swetlana Swarup, Johannes Knolle +1
Recent Raman experiments on the Kitaev material -RuCl have reported a finite Raman circular dichroism (RCD), revealing chiral phonon behaviour not expected from lattice symm…
Signatures of fractionalization in the optical phonons of hyperhoneycomb Kitaev magnet -LiIrO
Swetlana Swarup, Susmita Singh, Natalia B. Perkins
In this study, we propose that the signatures of spin fractionalization in quantum magnets can be identified through a detailed analysis of the temperature dependence of the asymme…
Footprints of the Kitaev spin liquid in the Fano lineshapes of the Raman active optical phonons
Kexin Feng, Swetlana Swarup, Natalia B. Perkins
We develop a theoretical description of the Raman spectroscopy in the spin-phonon coupled Kitaev system and show that it can provide intriguing observable signatures of fractionali…
Provable bounds for the Korteweg-de Vries reduction in multi-component Nonlinear Schrodinger Equation
Swetlana Swarup, Vishal Vasan, Manas Kulkarni
We study the dynamics of multi-component Bose gas described by the Vector Nonlinear Schrödinger Equation (VNLS), aka the Vector Gross--Pitaevskii Equation (VGPE) . Through a Madelu…
