An introduction to the problem of bridging quantum and classical dynamics

Simulating the exact quantum dynamics of realistic interacting systems is presently a task beyond reach but for the smallest of them, as the numerical cost for solving the time-dependent Schrodinger equation scales exponentially with the number of degrees ...

Communication: On the consistency of approximate quantum dynamics simulation methods for vibrational spectra in the condensed phase

Michele Ceriotti, Mariana Rossi Carvalho

Including quantum mechanical effects on the dynamics of nuclei in the condensed phase is challenging, because the complexity of exact methods grows exponentially with the number of quantum degrees of freedom. Efforts to circumvent these limitations can be ...

A comparison of different methods for fast single-cut near-to-far-field transformation [euraap corner]

Juan Ramon Mosig

Near-field-to-far-field transformation algorithms have been developed during the last decades of the last century. Spherical near-field measurements are nowadays the most accurate technique for characterizing one antenna. However, one of the drawbacks is t ...

Time-resolved measurements of suprathermal ion transport induced by intermittent plasma blob-filaments

Ambrogio Fasoli, Ivo Furno, Alexandre Dominique Bovet

Suprathermal ion turbulent transport in magnetized plasmas is generally non-diffusive, ranging from subdiffusive to superdiffusive depending on the interplay of the turbulent structures and the suprathermal ion orbits. Here, we present time-resolved measur ...

Playing quantum hide-and-seek with the muon: localizing muon stopping sites

Nicola Marzari

The most fundamental limitations of a muon-spin relaxation experiment can be the lack of knowledge of the implantation site of the muon and the uncertainty about the muon's perturbation of its host. Here we review some of the work done on the 'muon site pr ...

Nonlinear Quantum Optomechanics via Individual Intrinsic Two-Level Defects

Tobias Kippenberg, Vivishek Sudhir

We propose to use the intrinsic two-level system (TLS) defect states found naturally in integrated optomechanical devices for exploring cavity QED-like phenomena with localized phonons. The Jaynes-Cummings-type interaction between TLS and mechanics can rea ...

Nonlinearity in nanomechanical cantilevers

Luis Guillermo Villanueva Torrijo

Euler-Bernoulli beam theory is widely used to successfully predict the linear dynamics of micro-and nanocantilever beams. However, its capacity to characterize the nonlinear dynamics of these devices has not yet been rigorously assessed, despite its use in ...

Quantum-coherent coupling of a mechanical oscillator to an optical cavity mode

Tobias Kippenberg, Albert Schliesser, Stefan Alexander Weis

Optical laser fields have been widely used to achieve quantum control over the motional and internal degrees of freedom of atoms and ions(1,2), molecules and atomic gases. A route to controlling the quantum states of macroscopic mechanical oscillators in a ...

A hybrid on-chip optomechanical transducer for ultrasensitive force measurements

Tobias Kippenberg, Emanuel Gavartin

Nanoscale mechanical oscillators(1) are used as ultrasensitive detectors of force(2), mass(3) and charge(4). Nanomechanical oscillators have also been coupled with optical and electronic resonators to explore the quantum properties of mechanical systems(5) ...

On the Efficiency of Semiclassical and Classical Approximations of Quantum Fidelity in Many-Dimensional Systems

Cesare Mollica

This thesis is focused on classical and semiclassical approximations of a specific quantum time correlation function, the “quantum fidelity.” Namely, we rigorously study the efficiency of a continuous class of algorithms for the evaluation of its classical ...
