    The scaled-invariant Planckian metal and quantum criticality in Ce1−xNdxCoIn5

    The mysterious Planckian metal state, showing perfect T-linear resistivity associated with universal scattering rate, 1/τ = αkBT/ℏ with α ~ 1, has been observed in the normal state of various strongly correlated ...

    Helical Majorana fermions in -wave topological superconductivity of doped correlated quantum spin Hall insulators

    There has been growing interest in searching for exotic self-conjugate, charge-neutral low-energy fermionic quasi-particles, known as Majorana fermions (MFs) in solid state systems. Their signatures have been ...
