Electron-photon interaction in quantum dots : spin and entanglement [PDF]

, 2005
The interaction of electrons and photons lies at the heart of quantum physics. The most notable phenomena which are described by quantum physics but which obviously invalidate a classical description of the electromagnetic field - the photoelectric ...

Optimal Control Drives Ultrafast and Energy‐Efficient Magnetization Switching in Van der Waals Magnets

Advanced Materials, EarlyView.
ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...

Research Update: Spin transfer torques in permalloy on monolayer MoS2

APL Materials, 2016
We observe current induced spin transfer torque resonance in permalloy (Py) grown on monolayer MoS2. By passing rf current through the Py/MoS2 bilayer, field-like and damping-like torques are induced which excite the ferromagnetic resonance of Py.

Synchronization Phenomena in Spin Torque and Spin Hall Nano-Oscillators [PDF]

, 2017
Spin-torque oscillators (STOs) belong to a novel class of spintronic devices and exhibit a broad operating frequency and high modulation rates. STOs take advantage of several physical phenomena such as giant magnetoresistance (GMR), spin Hal effect (SHE),

Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

Advanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

Switching performance comparison between conventional SOT and STT-SOT write schemes with effect of shape deformation

AIP Advances, 2021
We demonstrate the effect of shape deformation in spin–orbit torque magnetoresistive random access memory (SOT-MRAM) based on micromagnetic simulation by generating 1000 randomly deformed samples using the exponentially decaying autocorrelation function.

Coherent state transfer between an electron and nuclear spin in (15)N@C(60). [PDF]

, 2011
Electron spin qubits in molecular systems offer high reproducibility and the ability to self-assemble into larger architectures. However, interactions between neighboring qubits are "always on," and although the electron spin coherence times can be ...
