Electrostatics of solvated systems in periodic boundary conditions

Continuum solvation methods can provide an accurate and inexpensive embedding of quantum simulations in liquid or complex dielectric environments. Notwithstanding a long history and manifold applications to isolated systems in open boundary conditions, the ...

Unstable Avoided Crossing in Coupled Spinor Condensates

Nathan Rafaël Bernier

We consider the dynamics of a Bose-Einstein condensate with two internal states, coupled through a coherent drive. We focus on a specific quench protocol, in which the sign of the coupling field is suddenly changed. At a mean-field level, the system is tra ...

Cavity Quantum Optomechanics: Coupling Light And Micromechanical Oscillators

Tobias Kippenberg, Albert Schliesser, Stefan Alexander Weis

Cavity optomechanics(1) is a new research field that has seen spectacular advances in recent years. Optomechanics combines advances in nano-and electromechanical systems with radiation pressure enabled control. The radiation pressure backaction enables to ...

A Quantum Dynamics Study of the Ultrafast Relaxation in a Prototypical Cu(I)-Phenanthroline

Majed Chergui, Ursula Röthlisberger, Ivano Tavernelli, Thomas James Penfold, Gloria Capano

The ultrafast nonadiabatic dynamics of a prototypical Cu(I)phenanthroline complex, Cu(dmp)(2) (dmp = 2,9-dimethyl-1,10-phenanthroline), initiated after photoexcitation into the optically bright metal-to-ligand charge-transfer (MLCT) state (S-3) is inv ...

Two Dimensional Quantum Mechanical Simulation of Low Dimensional Tunneling Devices

Mihai Adrian Ionescu, Cem Alper, Livio Lattanzio, José Luis Padilla de la Torre, Pierpaolo Palestri

We present a 2-D quantum mechanical simulation framework based on self-consistent solutions of Schrodinger-Poisson system, using the Finite Element Method. The quantum mechanical model includes direct as well as phonon-assisted transitions and it is applie ...

Multimode entanglement in coupled cavity arrays

Vincenzo Savona, Timothy Chi Hin Liew

We study a driven-dissipative array of coupled nonlinear optical resonators by numerically solving the von Neumann equation for the density matrix. We demonstrate that quantum correlated states of many photons can also be generated in the limit where the n ...

Relation of exact Gaussian basis methods to the dephasing representation: Theory and application to time-resolved electronic spectra

Jiri Vanicek, Miroslav Sulc

We recently showed that the dephasing representation (DR) provides an efficient tool for computing ultrafast electronic spectra and that further acceleration is possible with cellularization [M. Šulc and J. Vaníček, Mol. Phys. 110, 945 (2012)]. Here, we fo ...

Conduction of Ultracold Fermions Through a Mesoscopic Channel

Jean-Philippe Brantut

In a mesoscopic conductor, electric resistance is detected even if the device is defect-free. We engineered and studied a cold-atom analog of a mesoscopic conductor. It consists of a narrow channel connecting two macroscopic reservoirs of fermions that can ...
