Observation of Weyl nodes in TaAs

In 1929, H. Weyl proposed that the massless solution of the Dirac equation represents a pair of a new type of particles, the so-called Weyl fermions1. However, their existence in particle physics remains elusive after more than eight decades. Recently, sig ...

Orbit- and atom-resolved spin textures of intrinsic, extrinsic, and hybridized Dirac cone states

Jan Hugo Dil, Feng Liu, Chang Liu

Combining first-principles calculations and spin-and angle-resolved photoemission spectroscopy measurements, we identify the helical spin textures for three different Dirac cone states in the interfaced systems of a two-dimensional (2D) topological insulat ...

Quantum Monte Carlo Study of a Resonant Bose-Fermi Mixture

Gianluca Bertaina, Elisa Fratini

We study a resonant Bose-Fermi mixture at zero temperature by using the fixed-node diffusion Monte Carlo method. We explore the system from weak to strong boson-fermion interaction, for different concentrations of the bosons relative to the fermion compone ...

On the effective operators for Dark Matter annihilations

Alexander Monin, Andrea De Simone, Andrea Thamm

We consider effective operators describing Dark Matter (DM) interactions with Standard Model fermions. In the non-relativistic limit of the DM field, the operators can be organized according to their mass dimension and their velocity behaviour, i.e. whethe ...

Bio/CMOS Interfaces and Co-Design

Sandro Carrara

Understanding and mastering the key area of CMOS biointerfaces requires a plurality of skills going beyond traditional disciplines. Indeed, biosensor design requires knowledge of biology and chemistry, surface and semiconductor technology, and electronics. ...

Polarimetric control of reflective metasurfaces

Julien Perruisseau-Carrier

This letter addresses the synthesis of reflective cells approaching a given desired Floquet's scattering matrix. This work is motivated by the need to obtain much finer control of reflective metasurfaces by controlling not only their copolarized reflection ...

Heisenberg uncertainty principle as a probe of entanglement entropy: Application to superradiant quantum phase transitions

Pierre Marcel Nataf

Quantum phase transitions are often embodied by the critical behavior of purely quantum quantities such as entanglement or quantum fluctuations. In critical regions, we underline a general scaling relation between the entanglement entropy and one of the mo ...

Multiyear search for dark matter annihilations in the Sun with the AMANDA-II and IceCube detectors

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

A search for an excess of muon neutrinos from dark matter annihilations in the Sun has been performed with the AMANDA-II neutrino telescope using data collected in 812 days of live time between 2001 and 2006 and 149 days of live time collected with the AMA ...

SA2RAGE: A new sequence for fast B(1) (+) -mapping

Rolf Gruetter, Tobias Kober, José Pedro Rebelo Ferreira Marques, Florent Eggenschwiler

At high magnetic field strengths (≥3T), the radiofrequency wavelength used in MRI is of the same order of magnitude of (or smaller than) the typical sample size, making transmit magnetic field (B 1+) inhomogeneities more prominent. Methods such as radiofre ...

Multi-Valued Spin Switch in a Semiconductor Microcavity

Benoît Marie Joseph Deveaud, François Morier-Genoud, Taofiq Paraïso

In this work, we report on the first realization of multi-valued spin switching in the solid-state. We investigate the physics of spinor bistability with microcavity polaritons in a trap. Spinor interactions lead to special bistability regimes with decoupl ...
