Approximate symmetries of long-range Rydberg molecules including spin effects

Physical Review Research
An operator that generates an approximate symmetry of long-range Rydberg molecules (LRRMs) formed by two alkali atoms, one in a Rydberg state and the other in the ground state, is identified.

Numerical evaluation of energy shifts due to dipole moments interaction in a hydrogen atom

African Scientific Reports
This study aimed to numerically investigate the impact of dipole-dipole interactions on the energy levels of a hydrogen atom, specifically the energy shift caused by the interaction of the atom's dipole moment with external electric fields. This research

Induced quantum numbers of a magnetic vortex at nonzero temperature

, 2005
The phenomenon of the finite-temperature induced quantum numbers in fermionic systems with topological defects is analyzed. We consider an ideal gas of twodimensional relativistic massive electrons in the background of a defect in the form of a pointlike

Electronic Structure Reorganization in MPS3 via d‐Shell‐Selective Alkali Metal Doping

Advanced Science, EarlyView.
Alkali metal doping of layered MPS3 antiferromagnets reveals d‐shell‐selective responses. While MnPS3 resists charge transfer due to its half‐filled 3d5 shell, FePS3 and NiPS3 behave similarly to CoPS3 by accommodating extra d‐electrons. Yet only CoPS3, with its least stable d‐shell, undergoes pronounced band restructuring and a semiconducting‐to ...

Full confirmation of icosahedral Bose-Einstein statistics in cold ^{12}C_{60}

Physical Review Research
The quantum mechanical nature of high icosahedral symmetry, spherical top molecules, such as ^{12}C_{60}, is particularly evident at low total angular momentum quantum number J.

Total angular momentum representation for atom-molecule collisions in electric fields

, 2012
It is shown that the atom-molecule collision problem in the presence of an external electric field can be solved using the total angular momentum representation in the body-fixed coordinated frame, leading to a computationally efficient method for ab ...

Laser‐Induced Ultrafast Magnetic Phase Transition in 2D Van Der Waals Antiferromagnetic Heterostructures

Advanced Science, EarlyView.
In this work, ultrafast laser‐induced spin transfer and spin relaxation dynamics in 2D van der Waals antiferromagnetic CrI3/CrGeTe3 heterostructures are investigated. Laser excitation is demonstrated to induce pronounced interlayer nonequilibrium spin dynamics and ultrafast magnetic moment reconstruction, driving a transition from an antiferromagnetic (

Magnetic field sensing based on phase Ramsey interferometry with Bose condensed 87Rb atomic gases

Shenzhen Daxue xuebao. Ligong ban
Magnetic field sensing utilizing Bose-condensed atomic gases can achieve both high sensitivity and spatial resolution. Employing two-photon transitions from F=1, mF=1→F=2, mF=-1 (F is the quantum number of total atomic angular momentum, mF is the ...

Two-Body T-Matrices without Angular Momentum Decomposition: Energy and Momentum Dependencies

, 1997
The two-body t-matrix is calculated directly as function of two vector momenta for different Malfliet-Tjon type potentials. At a few hundred MeV projectile energy the total amplitude is quite a smooth function showing only a strong peak in forward ...

Photon‐Sphere Modes in Curved Optical Microcavities: A Black‐Hole Analogue Laser

Advanced Science, EarlyView.
An optical analogue of a Schwarzschild black hole is realized using curved microcavities that preserve light‐like geodesics. A new family of laser modes confined around the photon sphere is identified alongside conventional whispering‐gallery modes. Analytical theory, numerical simulations, and experiments reveal curvature‐induced confinement, enabling
