Manipulation of localized excitons in CrPS by temperature and magnetic field
Dipankar Jana, Swagata Acharya, Amit Pawbake +9
Layered van der Waals magnetic semiconductors provide a versatile platform for exploring excitonic phenomena intertwined with spin and lattice degrees of freedom, enabling excitons…
Spin-flip optical excitations in van der Waals antiferromagnet CrPS
Dipankar Jana, Aljoscha Soll, Zdenek Sofer +4
We investigate the near-infrared optical response of the semiconducting van der Waals antiferromagnet CrPS and identify previously unreported spin-entangled optical resonances.…
Deconstruction of the anisotropic magnetic interactions from spin-entangled optical excitations in van der Waals antiferromagnets
Dipankar Jana, Swagata Acharya, Milan Orlita +5
Magneto-optical excitations in antiferromagnetic d systems can originate from a multiplicity of light-spin and spin-spin interactions, as the light and spin degrees of freedom can…
Strong and selective magnon-phonon coupling in van der Waals antiferromagnet CoPS
Dipankar Jana, Diana Vaclavkova, Rajesh Kumar Ulaganathan +6
The Raman scattering response of the biaxial antiferromagnet CoPS has been investigated as a function of both magnetic field and temperature. The peaks observed in the low-freq…
Dynamics of surface electrons in a topological insulator: cyclotron resonance at room temperature
I. Mohelsky, F. Le Mardele, J. Dzian +13
The ability to manipulate the surface states of topological insulators using electric or magnetic fields under ambient conditions is a key step toward their integration into future…
Rydberg series of intralayer K-excitons in WSe multilayers
Piotr Kapuscinski, Artur O. Slobodeniuk, Alex Delhomme +6
Semiconducting transition metal dichalcogenides of group VI are well-known for their prominent excitonic effects and the transition from an indirect to a direct band gap when reduc…
Tuning THz magnons in a mixed van-der-Waals antiferromagnet
F. Le Mardele, I. Mohelsky, D. Jana +9
Alloying stands out as a pivotal technological method employed across various compounds, be they metallic, magnetic, or semiconducting, serving to fine-tune their properties to mee…
The temperature influence on the brightening of neutral and charged dark excitons in WSe monolayer
Ł. Kipczak, N. Zawadzka, D. Jana +9
The optically dark states play an important role in the electronic and optical properties of monolayers (MLs) of semiconducting transition metal dichalcogenides. The effect of temp…
Hybridization of terahertz phonons and magnons in disparate and spatially-separated material specimens
Marcin Białek, Yanko Todorov, Kamil Stelmaszczyk +6
The interaction between light and matter in condensed matter excitations and electromagnetic resonators serves as a rich playground for fundamental research and lies at the core of…
Transverse and longitudinal magnons in strongly anisotropic antiferromagnet FePSe3
F. Le Mardele, A. El Mendili, M. E. Zhitomirsky +7
FePSe3 is a collinear honeycomb antiferromagnet with an easy-axis anisotropy and large spins S=2. It belongs to a family of magnetic van der Waals materials, which recently attract…
Exchange-split multiple Rydberg series of excitons in anisotropic quasi two-dimensional ReS
P. Kapuściński, J. Dzian, A. O. Slobodeniuk +6
We perform a polarization-resolved magnetoluminescence study of excitons in ReS. We observe that two linearly polarized Rydberg series of excitons are accompanied by two other…
Magneto-optics of massive Dirac fermions in bulk Bi2Se3
M. Orlita, B. A. Piot, G. Martinez +13
We report on magneto-optical studies of Bi2Se3, a representative member of the 3D topological insulator family. Its electronic states in bulk are shown to be well described by a si…
