Self-Consistent Evolution of Magnetic Fields and Chiral Asymmetry in the Early Universe

We show that the evolution of magnetic fields in a primordial plasma, filled with standard model particles at temperatures T greater than or similar to 10 MeV, is strongly affected by the chiral anomaly-an effect previously neglected. Although reactions, e ...

Test Vehicle for Studying Thermal Conductivity of Die Attach Adhesives for High Temperature Electronics

Peter Ryser, Thomas Maeder, Fabrizio Vecchio, Conor Joseph Slater

Polymer adhesives offer a viable method for mounting silicon dies for high temperature applications. Here a test vehicle for comparing the thermal conductivity of different die attach materials is presented. The setup can be used to determine the degree of ...

Long-Lived States to Monitor Protein Unfolding by Proton NMR

Geoffrey Bodenhausen, Aurélien Bornet, Paul Romeo Vasos, Riddhiman Sarkar, Puneet Ahuja

The relaxation of long-lived states (LLS) corresponds to the slow return to statistical thermal equilibrium between symmetric and antisymmetric proton spin states. This process is remarkably sensitive to the presence of external spins and can be used to ob ...

Hydrodynamic Instabilities in Well-Balanced Finite Volume Schemes for Frictional Shallow Water Equations. The Kinematic Wave Case

Martin Rentschler

We report the developments of hydrodynamic instabilities in several well-balanced finite volume schemes that are observed during the computation of the temporal evolution of an out-balance flow which is essentially a kinematic wave. The numerical simulatio ...

Phase separation in binary eye lens protein mixtures

Nicolas Dorsaz, Giuseppe Foffi

Liquid–liquid phase separation occurs in young mammalian eye lenses and in concentrated solutions of isolated eye lens proteins, and has been linked to some forms of cataract. Here we study theoretically the protein compositions and cloud temperatures of t ...

Hydrodynamic nucleation of quantized vortex pairs in a polariton quantum fluid

Benoît Marie Joseph Deveaud, Gaël Nardin, Gabriele Grosso, François Morier-Genoud, Barbara Pietka

Quantized vortices appear in quantum gases at the breakdown of superfluidity. In liquid helium and cold atomic gases, they have been indentified as the quantum counterpart of turbulence in classical fluids. In the solid state, composite light-matter bosons ...

Condensation phase diagram of cavity polaritons in GaN-based microcavities: Experiment and theory

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Eric Feltin, Jacques Levrat

The evolution of the polariton condensation threshold (P-thr) under incoherent optical pumping is investigated both theoretically and experimentally over a wide range of temperatures (4-340 K) and exciton-cavity photon detunings (-120-0 meV) in a multiple ...

A partition-free approach to transient and steady-state charge currents

We construct a non-equilibrium steady state and calculate the corresponding current for a mesoscopic Fermi system in the partition-free setting. To this end we study a small sample coupled to a finite number of semi-infinite leads. Initially, the whole sys ...

Superfluidity of a nonequilibrium Bose-Einstein condensate of polaritons

Vincenzo Savona

We study theoretically superfluidity in a driven-dissipative Bose gas out of thermal equilibrium, and discuss the relation with conventional superfluids. We show how the superfluid behavior is characterized by a dramatic increase in the lifetime of a quant ...
