Diamagnetic vortices in Chern-Simons theory

Yannis Burnier, Eray Sabancilar

We find a new type of topological vortex solution in the U(1)(Z) xU(1)(A) Chern-Simons gauge theory in the presence of a U(1)(A) magnetic field background. In this theory U(1)(Z) is broken spontaneously by the U(1)(A) magnetic field. These vortices exhibit ...

Ab initio simulation of particle momentum distributions in high-pressure water

Michele Ceriotti

Applying pressure to water reduces the average oxygen-oxygen distance, and facilitates the delocalisation of protons along the hydrogen bond. This pressure-induced delocalisation is further enhanced by the quantum nature of hydrogen nuclei, which is very s ...

Combinatorics of loop equations for branched covers of sphere

Nicolas Gerson Orantin

We prove, in a purely combinatorial way, the spectral curve topological recursion for the problem of enumeration of bi-colored maps, which in a certain way generalize the notion of dessins d'enfant. Furthermore, we give a proof of the quantum spectral curv ...

A kinetic neutral atom model for tokamak scrape-off layer tubulence simulations

Paolo Ricci, Federico David Halpern, Fabio Riva, Christoph Wersal

The first-principle understanding of the processes in the Scrape-Off-Layer (SOL) of a tokamak is crucial for the developement of a thermonuclear re- actor. Since the plasma temperature in the SOL is rather low, the plasma is typically not fully ionized, an ...

Alternative method for the quantitative determination of Rashba- and Dresselhaus spin–orbit interaction using the magnetization

Dirk Grundler

The quantum oscillatory magnetization M of a two-dimensional electron system in a magnetic field B is found to provide quantitative information on both the Rashba- and Dresselhaus spin-orbit interaction (SOI). This is shown by first numerically solving the ...

Measurements of B Meson Lifetime Ratios with the LHCb Detector

Johan Luisier

The LHCb experiment is one of the four main experiments at the Large Hadron Collider (LHC) at CERN. The LHCb detector is a one-arm spectrometer dedicated to precise measurements of the CP-violation and studies or rare b-hadron decays. The centre of mass en ...

Quantum-statistical properties of the emission from two-level atoms embedded in coupled cavities

Paolo Schwendimann, Antonio Quattropani

The quantum-statistical properties of the radiation emitted from two coupled cavities containing one or two two-level atoms are discussed, and both configurations are compared. The results concerning stationary photon statistics, photon blocking, squeezing ...

Quantum leptogenesis I

Marco Drewes

Thermal leptogenesis explains the observed matter-antimatter asymmetry of the universe in terms of neutrino masses, consistent with neutrino oscillation experiments. We present a full quantum mechanical calculation of the generated lepton asymmetry based o ...

PT-Symmetric Periodic Optical Potentials

In quantum theory, any Hamiltonian describing a physical system is mathematically represented by a self-adjoint linear operator to ensure the reality of the associated observables. In an attempt to extend quantum mechanics into the complex domain, it was r ...

The quantum mechanics of perfect fluids

Riccardo Rattazzi, Solomon G Shamsuddin Osman Endlich

We consider the canonical quantization of an ordinary fluid. The resulting long-distance effective field theory is derivatively coupled, and therefore strongly coupled in the UV. The system however exhibits a number of peculiarities, associated with the vo ...
