On-chip Germanium nanowires for hole spin qubits

The creation of a universal quantum computer that can solve complex problems beyond the reach of classical computers - the so-called "quantum supremacy" - is an open challenge. For this to become a reality, a large number of qubits should be integrated in ...

Liquid-phase electron microscopy of electrochemical processes: Microcells configuration, corrosion of aluminium current collector and lithium-ion battery cycling

Morgan Julien André Barbey-Binggeli

Electrochemical liquid-phase electron microscopy (ec-LPEM) has been seen as a promising technique for revealing new insights into electrochemical phenomena that occur at the micro- and nanoscale levels, particularly at the solid-liquid interface. Specifica ...

Modified Huygens Source for Maximum Gain of Implanted Antenna

Jiajun Li, Anja Skrivervik

Implanted antennas are a key part of wireless implanted medical devices. However, the lossy nature of the surrounding body tissue significantly reduces their radiation efficiency and gain. Therefore, it is important to maximize the power reaching free spac ...

Ultrafast momentum-resolved visualization of the interplay between phonon-mediated scattering and plasmons in graphite

Rémi Marcel Léon Claude, Fabrizio Carbone, Thomas La Grange, Ivan Madan, Michele Puppin, Francesco Barantani, Alexey Sapozhnik, Bruce Michael Raleigh Weaver

Scattering between charges and collective modes in materials governs phenomena such as electrical resistance, energy dissipation, and phase switching. Studying such scattering requires simultaneous access to ultrafast and momentum-resolved dynamics of sing ...

Weyl spin-momentum locking in a chiral topological semimetal

Jan Hugo Dil, Eduardo Bonini Guedes

Spin-orbit coupling in noncentrosymmetric crystals leads to spin-momentum locking - a directional relationship between an electron's spin angular momentum and its linear momentum. Isotropic orthogonal Rashba spin-momentum locking has been studied for decad ...

Pioneering non-thermal plasma as a defect passivator: a new Frontier in ambient metal halide perovskite synthesis

Mohammad Khaja Nazeeruddin

Growing energy demands make cost-effective, high-performance perovskite solar cells (PSCs) desirable. However, their commercial applications are limited due to defect formation and instability. Passivation technologies help enhance their favorable traits. ...

Decoherence in a crystal-phase defined double quantum dot charge qubit strongly coupled to a high-impedance resonator

Pasquale Scarlino

Decoherence of a charge qubit is usually credited to charge noise in the environment. Here we show that charge noise may not be the limiting factor for the qubit coherence. To this end, we study coherence properties of a crystal-phase defined semiconductor ...

Fluxonium qubits in a flip-chip package

Vladimir Manucharyan

The strong anharmonicity and high coherence times inherent to fluxonium superconducting circuits are beneficial for quantum information processing. In addition to requiring high-quality physical qubits, a quantum processor needs to be assembled in a manner ...

Analytical Modeling of Short-Channel MOSFET Differential Pair Non-Linearity

Christian Enz, Andreas Peter Burg, Catherine Dehollain, Hung-Chi Han

Energy efficiency is of utmost importance in modern applications. Power consumption optimisation could be improved by a comprehensive analytical modeling of the characteristics of critical blocks in a system. Dynamic range (DR) has a strong effect on the p ...

Complete field-induced spectral response of the spin-1/2 triangular-lattice antiferromagnet CsYbSe2

Bruce Normand, Andreas Martin Läuchli Herzig

Fifty years after Anderson's resonating valence-bond proposal, the spin-1/2 triangular-lattice Heisenberg antiferromagnet (TLHAF) remains the ultimate platform to explore highly entangled quantum spin states in proximity to magnetic order. Yb-based delafos ...

Prospects for detecting the circum- and intergalactic medium in X-ray absorption using the extended intracluster medium as a backlight

Yannick Michael Bahé

The warm-hot plasma in cosmic web filaments is thought to comprise a large fraction of the gas in the local Universe. So far, the search for this gas has focused on mapping its emission, or detecting its absorption signatures against bright, point-like sou ...
