Bose-Fermi Mapping and Multi-Branch Spin Chain Model for Strongly Interacting Quantum Gases in One-Dimension: Dynamics and Collective Excitations
We show that the wave function of a one dimensional spinor gas with contact
-wave interaction, either bosonic or fermionic, can be mapped to the direct
product of the wave function of a spinless Fermi gas with short-range -wave
interaction and that of a spin system governed by spin parity projection
operators. Applying this mapping to strongly interacting spinor gases, we
obtain a generalized spin chain model that captures both the static and
dynamics properties of the system. Using this spin chain model, we investigate
the breathing mode frequency and the quench dynamics of strongly interacting
harmonically trapped spinor gases.Comment: 5 pages of main text + 5 pages of Supplemental Materia
Imaging blood cells through scattering biological tissue using speckle scanning microscopy
Using optical speckle scanning microscopy [1], we demonstrate that clear
images of multiple cells can be obtained through biological scattering tissue,
with subcellular resolution and good image quality, as long as the size of the
imaging target is smaller than the scanning range of the illuminating speckle
pattern.Comment: Copyright statement remove
