Entanglement, squeezing and state-swap in cholesteric liquid crystals
J. D. P. Machado, Ya. M. Blanter
Phenomena such as state-swap, quadrature squeezing, entanglement and violation of entanglement inequalities are frequently reported to occur in quantum systems only. It is shown he…
Realization of the degenerate parametric oscillator in electromechanical systems
E. Jansen, J. D. P. Machado, Ya. M. Blanter
We consider an electromechanical system where a microwave cavity is coupled to a mechanical resonator, with a mechanical frequency twice the microwave frequency. In this regime, th…
A universal tensor network algorithm for any infinite lattice
Saeed S. Jahromi, Roman Orus
We present a general graph-based Projected Entangled-Pair State (gPEPS) algorithm to approximate ground states of nearest-neighbor local Hamiltonians on any lattice or graph of inf…
Optomechanical damping as the origin of sideband asymmetry
J. D. P. Machado, Ya. M. Blanter
Sideband asymmetry in cavity optomechanics has been explained by particle creation and annihilation processes, which bestow an amplitude proportional to 'n+1' and 'n' excitations t…
Quantum nonlinear dynamics of optomechanical systems in the strong coupling regime
J. D. P. Machado, Ya. M. Blanter
With an increasing coupling between light and mechanics, nonlinearities begin to play an important role in optomechanics. We solve the quantum dynamics of an optomechanical system…
Dynamical structure factors of the spin-1/2 XXX chain at finite magnetic field
J. M. P. Carmelo, P. D. Sacramento, D. K. Campbell
We study the dynamical structure factors of the spin-1/2 XXX chain at finite magnetic field h, focusing in particular on the singularities at excitation energies in the vicinity of…
