The Langevin-equation description of optomechanics with the dispersive and dissipative optomechanical coupling

Alexander K. Tagantsev

The description of the optomechanical systems is commonly based on the quantum Langevin equation formalism. This framework is introduced phenomenologically or based on a model Hami…

Photovoltaic creation of charged domain walls in barium titanate

P. S. Bednyakov, P. V. Yudin, A. K. Tagantsev +1

The optical control of domain structures in ferroelectrics is of great interest. In the present work, we demonstrate the reliable creation of charged domain walls - conductive chan…

Paradoxical creation of a polydomain pattern by electric field in BaTiO3 crystal

Petr S. Bednyakov, Petr V. Yudin, Alexander K. Tagantsev +1

It is known that ferroelectric single crystals can be turned from a polydomain to a monodomain state by the application of an electric field. Here we report an unexpected opposite…

Generation of squeezed Fock states by measurement

S. B. Korolev, E. N. Bashmakova, A. K. Tagantsev +1

The generation of squeezed Fock states by the one or more photon subtraction from a two-mode entangled Gaussian (TMEG) state is theoretically addressed. We showed that an arbitrary…

Optimal optomechanical cavity setups with highly reflecting membranes

Georg Enzian, Eugene S. Polzik, Alexander K. Tagantsev

Highly reflecting mechanically compliant membranes based on photonic-crystal patterns have recently gained increasing attention within cavity optomechanics due to their prospects o…

Phononically shielded photonic-crystal mirror membranes for cavity quantum optomechanics

Georg Enzian, Zihua Wang, Anders Simonsen +6

We present a highly reflective, sub-wavelength-thick membrane resonator featuring high mechanical quality factor and discuss its applicability for cavity optomechanics. The $88.5~\…
