Phase-Separation Transition in Liquid Mixtures Near Charged Objects

Gilad Marcus, Sela Samin, Yoav Tsori

We study the thermodynamic behavior of nonpolar liquid mixtures in the vicinity of curved charged objects, such as electrodes or charged colloids. For small enough charge on the ob…

Computational Complexity of interacting electrons and fundamental limitations of Density Functional Theory

Norbert Schuch, Frank Verstraete

One of the central problems in quantum mechanics is to determine the ground state properties of a system of electrons interacting via the Coulomb potential. Since its introduction…

Entanglement renormalization and topological order

Miguel Aguado, Guifre Vidal

The multi-scale entanglement renormalisation ansatz (MERA) is argued to provide a natural description for topological states of matter. The case of Kitaev's toric code is analyzed…

Conceptual problems in phenomenological interpretation in searches for variation of constants & violation of various invariances

Savely G. Karshenboim

At present a number of current or proposed experiments are directed towards a search for a `new physics' by detecting variations of fundamental physical constants or violations of…

Guide for atomic and particle physicists to CODATA's recommended values of the fundamental physical constants

Savely G. Karshenboim

The CODATA recommended values of the fundamental constants are widely applied in particle, nuclear and atomic physics. They are a result of a complicated evaluation (adjustment) of…

Dynamical creation of bosonic Cooper-like pairs

T. Keilmann, J. J. Garcia-Ripoll

We propose a scheme to create a metastable state of paired bosonic atoms in an optical lattice. The most salient features of this state are that the wavefunction of each pair is a…

Emission spectra of atoms with non-Markovian interaction: Fluorescence in a photonic crystal

Ines de Vega, Daniel Alonso

We present a formula to evaluate the spontaneous emission spectra of an atom in contact with a radiation field with non-Markovian effects. This formula is written in terms of a two…

Sequential Implementation of Global Quantum Operations

L. Lamata, J. Leon, D. Perez-Garcia +2

We study the possibility for a global unitary applied on an arbitrary number of qubits to be decomposed in a sequential unitary procedure, where an ancillary system is allowed to i…

Assessing non-Markovian dynamics

M. M. Wolf, J. Eisert, T. S. Cubitt +1

We investigate what a snapshot of a quantum evolution - a quantum channel reflecting open system dynamics - reveals about the underlying continuous time evolution. Remarkably, from…

Mesoscopic Spin-Boson Models of Trapped Ions

D. Porras, F. Marquardt, J. von Delft +1

Trapped ions arranged in Coulomb crystals provide us with the elements to study the physics of a single spin coupled to a boson bath. In this work we show that optical forces allow…
