2 days ago · Spin is an intrinsic form of angular momentum carried by elementary particles, and thus by composite particles such as hadrons, atomic nuclei, and atoms. [1] [2] : 183 –184 Spin is quantized, and accurate models for the interaction with spin require relativistic quantum mechanics or quantum field theory . The existence of electron spin ...
3 days ago · Quantum mechanics is a fundamental theory in physics that describes the behavior of nature at and below the scale of atoms. [2] : 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science . Quantum mechanics can describe many systems that ...
May 23, 2024 · The elements of () are the "infinitesimal generators" of rotations, i.e., they are the elements of the tangent space of the manifold SO(3) at the identity element. If R ( ϕ , n ) {\displaystyle R(\phi ,{\boldsymbol {n}})} denotes a counterclockwise rotation with angle φ about the axis specified by the unit vector n , {\displaystyle ...
May 20, 2024 · The proximal nuclear spins, coupled to the electronic spin, present an opportunity for the realization of long-lived quantum registers for the electronic spin qubit—a critical element for large ...
May 24, 2024 · Many of today's quantum devices rely on collections of qubits, also called spins. These quantum bits have only two energy levels, the '0' and the '1'. However, spins in real devices also interact ...
May 7, 2024 · providing new advanced optical elements for applications to high-resolution microscopy, optical micro-manipulation, and classical and quantum information. 2 Material and methods 2.1 Dual-functional metalenses design In this work, we propose a spin-dependent dielectric metasurface made of a squared lattice (period of the lattice u =

6 days ago · The calculated spin-down d-band center is found to be higher for Fe atoms than for Ni atoms, −0.174 and −1.241 eV, respectively. Additionally, Fe atoms in the NiFe 1:5-BHT and NiFe 5:1-BHT display an even more positive spin-down d-band center, −0.117 and −0.059 eV, respectively. The alteration in the d-band center correlates with the ...
