Critical Temperature and Condensate Fraction of a Fermion Pair Condensate
Yasuhisa Inada, Munekazu Horikoshi, Shuta Nakajima +3
We report on measurements of the critical temperature and the temperature dependence of the condensate fraction for a fermion pair condensate of 6Li atoms. The Bragg spectroscopy i…
Dynamical symmetry in spinor Bose-Einstein condensates
Shun Uchino, Takaharu Otsuka, Masahito Ueda
We demonstrate that dynamical symmetry plays a crucial role in determining the structure of the eigenspectra of spinor Bose-Einstein condensates (BECs). In particular, the eigenspe…
Second Law of Thermodynamics with Discrete Quantum Feedback Control
Takahiro Sagawa, Masahito Ueda
A new thermodynamic inequality is derived which leads to the maximum work that can be extracted from multi-heat baths with the assistance of discrete quantum feedback control. The…
Density-Matrix Renormalization Group Study of Trapped Imbalanced Fermi Condensates
Masaki Tezuka, Masahito Ueda
The density-matrix renormalization group is employed to investigate a harmonically-trapped imbalanced Fermi condensate based on a one-dimensional attractive Hubbard model. The obta…
Stabilization of a Bose-Einstein droplet by hyperfine Rabi oscillations
Hiroki Saito, Randall G. Hulet, Masahito Ueda
A self-trapped Bose-Einstein condensate is shown to be stabilized in two-dimensional free space by Rabi oscillations between two hyperfine states which make an effective interatomi…
Accuracy matrix in generalized simultaneous measurement of a qubit system
Takahiro Sagawa, Masahito Ueda
We formulate the accuracy of quantum measurement for a qubit system in terms of a 3 by 3 matrix. This matrix, which we refer to as the accuracy matrix, can be calculated from a pos…
