Circular Magneto-Optical Trap for Neutral Atoms [PDF]

open access: yesJournal of the Physical Society of Japan, 2008
We propose and experimentally demonstrate a novel scheme to magneto-optically trap neutral atoms in a ring shaped trap that can be used to transfer atoms into a circular magnetic trap with high density. This inturn enables to evaporatively cool atoms and study the behaviour of ultra cold gases in a periodic 2-dimensional potential. The circular magneto-

Three-dimensional Doppler, polarization-gradient, and magneto-optical forces for atoms and molecules with dark states

open access: yesNew Journal of Physics, 2016
We theoretically investigate the damping and trapping forces in a three-dimensional magneto-optical trap (MOT), by numerically solving the optical Bloch equations. We focus on the case where there are dark states because the atom is driven on a ‘type-II’

Versatile Magneto‐Dielectric Response of Epitaxial Thin Films of the High Entropy Oxide Perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3

open access: yesAdvanced Materials, Volume 38, Issue 26, 8 May 2026.
The magnetic high entropy oxide perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3 exhibits a substantially large dielectric constant (εr) at room temperature, which shows distinct anionic and cationic contributions in the form of zero and finite bias peaks, respectively, down to its magnetic transition temperature (Tmag).

Bose-Einstein Condensation in a Surface Micro Trap

open access: yes, 2001
Bose-Einstein condensation has been achieved in a magnetic surface micro trap with 4x10^5 87Rb atoms. The strongly anisotropic trapping potential is generated by a microstructure which consists of microfabricated linear copper conductors at a width ...

Black Phosphorus‐Based Nanocomposites as Anode Materials for Lithium‐Ion Batteries: A Comprehensive Review

open access: yesBattery Energy, Volume 5, Issue 3, May 2026.
Multifunctional black phosphorus nanocomposites with carbon, metal/oxide, and polymers suppress volume expansion, enhance conductivity, and enable durable, high‐capacity LIB anodes. ABSTRACT Black phosphorus (BP) is a layered and two‐dimensional substance that has been discussed as an anode material for lithium‐ion batteries (LIBs) due to its ...

The Blue-Detuned Magneto-Optical Trap

open access: yes, 2017
It has been more than 30 years since the first demonstration of a magneto-optical trap (MOT) using sodium atoms. Since then the MOT has revolutionised the field of atomic physics by facilitating the emergence of a broad range of productive avenues of research using atoms prepared at low temperatures and high densities.

Direct Frequency Comb Laser Cooling and Trapping

open access: yesPhysical Review X, 2016
Ultracold atoms, produced by laser cooling and trapping, have led to recent advances in quantum information, quantum chemistry, and quantum sensors. A lack of ultraviolet narrow-band lasers precludes laser cooling of prevalent atoms such as hydrogen ...

Clinical Applications of Electrical Conductivity Imaging Using MRI

open access: yesJournal of Magnetic Resonance Imaging, Volume 63, Issue 5, Page 1224-1245, May 2026.
ABSTRACT Magnetic resonance imaging (MRI) has emerged as a noninvasive technique for probing the electrical properties of biological tissues: electrical conductivity and relative permittivity. This review focuses on the electrical conductivity and provides a comprehensive overview of applications across both low‐ and high‐frequency regimes.

Laboratory Courses on Laser Spectroscopy and Atom Trapping

open access: yesAtoms, 2020
We present an overview of experiments covered in two semester-length laboratory courses dedicated to laser spectroscopy and atom trapping. These courses constitute a powerful approach for teaching experimental physics in a manner that is both ...
