Electric field control of SrVO3 double quantum well [PDF]

APL Materials
Field-effect transistors are widely used to control carrier density in a channel of a semiconductor by a gate voltage. Mott transistors employing strongly correlated electron systems as a channel are particularly intriguing due to their switching ...

Gapped nodal planes and large topological Nernst effect in the chiral lattice antiferromagnet CoNb3S6

Nature Communications
The electronic structure of compensated antiferromagnets (CAF) creates large functional responses, reminiscent of ferromagnets and suitable for data storage and readout, despite (nearly) net-zero spontaneous magnetization. Many experimental signatures of

Terahertz photon to dc current conversion via magnetic excitations of multiferroics

Nature Communications
Direct conversion from terahertz photon to charge current is a key phenomenon for terahertz photonics. Quantum geometrical description of optical processes in crystalline solids predicts existence of field-unbiased dc photocurrent arising from terahertz ...

Low-temperature hysteresis broadening emerging from domain-wall creep dynamics in a two-phase competing system

Communications Materials, 2023
Hysteretic behaviour accompanies any first-order phase transition, forming a basis for many applications. However, its quantitative understanding remains challenging, and even a qualitative understanding of pronounced hysteresis broadening at low ...

Coherent Resonant Soft X-ray Scattering Study of Magnetic Textures in FeGe

Quantum Beam Science, 2018
Coherent resonant soft X-ray scattering was utilized to examine the magnetic textures in a thin plate of the cubic B20 compound FeGe. Small-angle scattering patterns were measured with controlled temperatures and magnetic fields exhibiting magnetic ...

The supersolid phase of matter

Il Colle di Galileo, 2021
The supersolid is a phase of matter intermediate between a crystal and a superfluid. It was predicted more than fifty years ago, long sought in solid helium and only recently discovered in a quantum gas of magnetic atoms. This article explains how we came to discover the supersolid, how some surprising properties have already been characterized and ...

Quantum Hall states observed in thin films of Dirac semimetal Cd3As2

Nature Communications, 2017
Despite many achievements in the topological semimetal Cd3As2, the high-quality Cd3As2 films are still rare. Here, Uchida et al. grow high-crystallinity and high-mobility Cd3As2 thin films and observe quantum Hall states dependent on the confinement ...
