Experimental entanglement swapping through single-photon χ(2) nonlinearity
The SFG-BSA configuration
Figure 1a shows a schematic of the SFG-BSA setup. A type-0 PPLN/W is incorporated in a Sagnac interferometer to extract two of the four Bell states in the polarization degree of freedom. It should be noted that this…

Unified theory of phonon in solids with phase diagram of non-Debye anomalies
We begin by abstracting an isotropic real solid as a homogeneous continuum model embedded with some scatterers. The system’s vibrations can be treated as the elastic phonons resonating with local modes. There are two system-averaged length…

Hund’s rule coupling and interlayer hybridization of intercalated transition metal dichalcogenides
Low-energy electronic structure
Although the intercalated TM 3d atoms in NbS2 significantly modify its magnetic and electronic structure, the dispersions around -1 eV to EF still mainly originate from NbS2 layers, as shown in Fig. 1b, c. The…
