Geometric squeezing into the lowest Landau level

چکیده
The equivalence between neutral particles under rotation and charged in a magnetic field relates phenomena as diverse spinning atomic nuclei, weather patterns, the quantum Hall effect. In their descriptions, translations along different directions do not commute, implying Heisenberg uncertainty relation spatial coordinates. Here, we exploit ability to squeeze non-commuting variables dynamically create Bose-Einstein condensate occupying single Landau gauge wavefunction lowest level. We directly resolve extent of zero-point cyclotron orbits, demonstrate geometric squeezing orbits' guiding centers by more than ${7}~$dB below standard limit. attains an angular momentum ${1000}\,{\hbar}$ per particle, interatomic distance comparable size orbits. This offers new route towards strongly correlated fluids bosonic states.

Anyons and Lowest Landau Level Anyons
Intermediate statistics interpolating from Bose statistics to Fermi statistics are allowed in two dimensions. This is due to the particular topology of the two dimensional configuration space of identical particles, leading to non trivial braiding of particles around each other. One arrives at quantum many-body states with a multivalued phase factor, which encodes the anyonic nature of particle...
متن کاملThe Electromagnetic Interactions of Electrons in the Lowest Landau Level
Starting from a system of planar electrons in a strong magnetic field normal to the plane, interacting with perturbing electromagnetic fields, an effective Lagrangian for the fermions in the lowest Landau level (L.L.L.) has been derived. By choosing a suitable background electrostatic potential, an incompressible droplet of these electrons is constructed. The gauge invariant effective Lagrangia...
متن کاملSkyrmion physics beyond the lowest Landau-level approximation
The effects of Landau-level mixing and finite thickness of the two-dimensional electron gas on the relative stability of Skyrmion and single spin-flip excitations at Landau-level filling factor n51 have been investigated. Landau-level mixing is studied by fixed-phase diffusion Monte Carlo, and finite thickness is included by modifying the effective Coulomb interaction. Both Landau-level mixing ...
متن کاملWhy the lowest Landau level approximation works in strongly type
Higher than the lowest Landau level contributions to magnetization and specific heat of superconductors are calculated using Ginzburg Landau equations approach. Corrections to the excitation spectrum around solution of these equations (treated perturbatively) are found. Due to symmetries of the problem leading to numerous cancellations the range of validity of the LLL approximation in mean fiel...
