We study elementary low energy excitations inside a supersolid. We find that the coupling between the longitudinal lattice vibration mode and the superfluid mode leads to two longitudinal modes (one upper branch and one lower branch) inside the supersolid, while the transverse modes in the supersolid stay the same as those inside a normal solid. We also work out various experimental signatures of these novel elementary excitations by evaluating the Debye-Waller factor, density-density…

Quantum phase transitions are among the most fantastic phenomena in Nature. Here we show that observing them in different inertial frames may lead to new quantum phases through novel quantum phase
Response of a strongly interacting spin-orbit coupling system to a Zeeman field
A strongly spin-orbital coupled systems could be in a magnetic ordered phase at zero field. However, a Zeeman field could drive it into different quantum or topological phases. In this work, starting
