Invited Speaker / Conférencier invité
Developing new methods for generating and detecting spin currents has been the central task of spintronics. In the pioneering work of Johnson and Silsbee, the generation and detection of spin-polarized currents were both achieved through the use of ferromagnetic metals (FM). Recent breakthroughs reveal ferromagnetic insulators (FI) to be promising spin current sources, in which spin currents...

Exciton-polaritons are half-light, half-matter quasi-particles formed by excitons strongly coupled to the confined electromagnetic field of a microcavity. Their very low effective mass ($< 10^{-4} m_e$) and their bosonic character allows a phase transition to a Bose-Einstein Condensate (BEC) at relatively high temperature. Quantum effects such as spontaneous macroscopic coherence and...

We study the phase transition of the escape rate of exchange-coupled dimer
of single-molecule magnets which are coupled either ferromagnetically or antiferromagnetically in a staggered magnetic field and an easy $z$-axis anisotropy. The Hamiltonian for this system has been used to study dimeric molecular nanomagnet [Mn$_4$]$_2$ which is comprised of two single molecule magnets coupled...

There is substantial interest in enhancing the Figure of Merit of thermoelectric materials in their applications to diverse fields such as energy and environmental studies [1,2]. The relationship between thermal and electrical conductivities is often described by the empirical Wiedemann-Franz law.
Improvisations beyond this law have been found to be necessary to extend its scope to broader...
