Poor man's Majorana bound states in quantum dot based Kitaev chain coupled to a photonic cavity

This paper demonstrates that embedding a quantum dot-based Kitaev chain in a photonic cavity allows for the engineering of "poor man's" Majorana bound states by using the cavity's photon state to screen particle interactions and reach the necessary sweet spot conditions, while also revealing that a large photon population suppresses hopping and creates a degenerate spectrum.

Heat flux deflection induced by hydrodynamic electron transport in a homogeneous Corbino disk under magnetic field

This study demonstrates that in a homogeneous 2D Corbino disk under a magnetic field, hydrodynamic electron transport induces a deflection of heat flux into the tangential direction, a phenomenon driven by momentum-conserving scattering and capable of reversing heat flow direction under specific electric or thermal gradients.
