Kondo lattices are ideal testbeds for the exploration of heavy-fermion quantum phases of
matter. While our understanding of Kondo lattices has traditionally relied on complex bulk f …

The collective modes of the superconducting order parameter fluctuation can provide key
insights into the nature of the superconductor. Recently, a family of superconductors has …

Using scanning tunneling microscopy and spectroscopy, for a monolayer of transition metal
dichalcogenide H-NbS2 grown by molecular beam epitaxy on graphene, we provide …

Ultrathin superconducting films are the basis of superconductor devices. van der Waals
(vdW) NbSe2 with noncentrosymmetry exhibits exotic superconductivity and shows promise …

The possibility of realizing pair density wave (PDW) phases, in which Cooper pairs have a
finite momentum, presents an interesting challenge that has been studied in a wide variety …

Ising superconductivity, observed in NbSe2 and similar materials, has generated
tremendous interest. Recently, attention was called to the possible role that spin fluctuations …

The recent discovery of Ising superconductivity has garnered much interest due in part to the
resilience of these superconductors to large in-plane magnetic fields. In this Perspective, we …

Here we report a low-temperature and vector-magnetic-field scanning tunneling microscopy/
spectroscopy (STM/S) study on 3R-TaSe2. The sample surface was obtained by exfoliating …

We propose using tunneling spectroscopy with a superconducting electrode to probe the
collective modes of unconventional superconductors. The modes are predicted to appear as …

We study theoretically a junction composed of a PT-symmetric non-Hermitian
superconductor (PTS) placed between two conventional superconductors. We show that …
