Nanomechanics has brought mesoscopic physics into the world of vibrations. Because
nanomechanical systems are small, fluctuations are significant, the vibrations already …

Cavity optomechanical systems enable interactions between light and mechanical
resonators, providing a platform both for fundamental physics of macroscopic quantum …

Quantum control of complex objects in the regime of large size and mass provides
opportunities for sensing applications and tests of fundamental physics. The realization of …

Entanglement, an essential feature of quantum theory that allows for inseparable quantum
correlations to be shared between distant parties, is a crucial resource for quantum …

In solid state physics, a bandgap (BG) refers to a range of energies where no electronic
states can exist. This concept was extended to classical waves, spawning the entire fields of …

Gaussian states have played an important role in the physics of continuous-variable
quantum systems. They are appealing for the experimental ease with which they can be …

In this work, we provide an overview of how well-established concepts in the fields of
quantum chemistry and material sciences have to be adapted when the quantum nature of …

Conversion between signals in the microwave and optical domains is of great interest both
for classical telecommunication and for connecting future superconducting quantum …

Quantum states of mechanical motion can be important resources for quantum information,
metrology and studies of fundamental physics. Recent demonstrations of superconducting …

Numerous astrophysical and cosmological observations are best explained by the existence
of dark matter, a mass density which interacts only very weakly with visible, baryonic matter …
