Optical orientation of carrier spins by circularly polarized light is the basic concept and tool of
spin physics in semiconductors. We study the optical orientation of electrons and holes in a …

Two-dimensional (2D) hybrid organic/inorganic perovskites are an emerging materials class
for optoelectronic and spintronic applications due to strong excitonic absorption and …

We present a general ab initio method based on Wannier functions using the covariant
derivative for simulating the photocurrent in solids. The method is widely applicable to …

Picosecond time-resolved and cw magneto-optical methods have been used for studying
the spin-related properties of excitons and photocarriers in methyl-ammonium lead bromide …

The hybrid organic–inorganic halide perovskite (HOIP), for example, MAPbBr3, exhibits
extended spin lifetime and apparent spin lifetime anisotropy in experiments. The underlying …

Quantum defects are atomic defects in materials that provide resources to construct quantum
information devices such as single-photon emitters and spin qubits. Recently, two …

We predict intrinsic spin relaxation times (T 1) of graphite due to spin-orbit–phonon
interaction, ie, spin-phonon interaction caused by spin-orbit coupling and electron-phonon …

The usefulness of solid-state spins in quantum technologies depends on how long they can
remain in a coherent superposition of quantum states. This Colloquium discusses how first …

Efficient conversion between charge currents and spin signals is crucial for realizing magnet-
free spintronic devices. However, the strong spin-orbit coupling that enables such a …

We investigate the circular photogalvanic effect (CPGE) in single-crystalline
methylammonium lead iodide microcrystals under a static electric field. The external electric …
