Thermoelectric effects in magnetic nanostructures [PDF]

, 2012
Elektronentransport is een belangrijk natuurkundig verschijnsel dat vaak wordt gebruikt in de hedendaagse technologie. Alle elektrische apparaten, variërend van stofzuigers tot computerchips, zijn in principe gebaseerd op dit type transport.

Stochastic webs and quantum transport in superlattices : an introductory review. [PDF]

, 2009
Stochastic webs were discovered, first by Arnold for multi-dimensional Hamiltonian systems, and later byChernikov et al. for the low-dimensional case. Generated by weak perturbations, they consist of thread-like regions of chaotic dynamics in phase space.

Universal Conductance Fluctuations in Quantum Anomalous Hall Insulators

Advanced Materials, EarlyView.
Universal conductance fluctuations are observed in mesoscopic quantum anomalous Hall insulators. Two distinct fluctuation patterns are identified, arising from different interference processes of bulk and chiral edge states, respectively. These findings unveil rich quantum interference phenomena in quantum anomalous Hall insulators and provide insights

Gapless Superconductivity From Extremely Dilute Magnetic Disorder in 2H‐NbSe2‐xSx

Advanced Materials, EarlyView.
We demonstrate that 2H‐NbSe2‐xSx hosts gapless superconductivity at unexpectedly low magnetic impurity concentrations. Combining STM, Bogoliubovde Gennes simulations, DFT, and quasiparticle interference, we comprehensively study the development of gapless behavior and show that SeS substitution reshapes the band structure, enhances nesting, and drives ...

Three-dimensional Dirac semimetal and magnetic quantum oscillations in Cd3As2 [PDF]

, 2017
Single crystals of topological Dirac semimetal Cd3As2 were synthesized using a modified vapour transport technique. The magnetization of Cd3As2 single crystals was measured in the temperature range from 4.2-300 K and magnetic field up to 5 T along [001 ...

Coherent states in microwave-induced resistance oscillations and zero resistance states

Physical Review Research
We investigate irradiated high-mobility two-dimensional electron systems (2DES) under low or moderated magnetic fields. These systems present microwave-induced magnetoresistance oscillations (MIRO) which, as we demonstrate, reveal the presence of ...

Signatures of Edge States in Antiferromagnetic Van der Waals Josephson Junctions

Advanced Materials, EarlyView.
ABSTRACT The combination of superconductivity and magnetic textures leads to unconventional superconducting phenomena, including new correlated and topological phases. Van der Waals (vdW) materials emerge as a versatile platform for exploring the interplay between these two competing orders.

The functional roles of alpha-band phase synchronization in local and large-scale cortical networks

Frontiers in Psychology, 2011
Alpha-frequency band (8-14 Hz) oscillations are among the most salient phenomena in human electroencephalography (EEG) recordings and yet their functional roles have remained unclear.

Thermal‐Driven Diode Polarity Switching From Competing Helical Superconducting States in WTe2/α‐Fe2O3 Heterostructures

Advanced Materials, EarlyView.
A Nb‐proximitized Josephson junction based on a WTe2/α‐Fe2O3 heterostructure exhibits a robust superconducting diode effect with programmable polarity. The diode direction can be trained by magnetic fields and switched by temperature cycling, revealing tunable finite‐momentum pairing states and competing superconducting states in symmetry‐broken ...

The de Haas van Alphen effect near a quantum critical end point in Sr₃Ru₂O₇ [PDF]

, 2009
Highly correlated electron materials are systems in which many new states of matter can emerge. A particular situation which favours the formation of exotic phases of the electron liquid in complex materials is that where a quantum critical point (QCP ...
