BCS Pairing Dynamics
نویسنده
چکیده
Experimental control over inter-atomic interactions by adjusting external parameters is discussed. Qualitatively different time evolution of the order parameter are predicted theoretically in ultracold atomic fermions with time-dependent pairing interaction. Following an abrupt change of the pairing strength, the order parameter undergoes undamped oscillation, damping oscillation and exponential decay in different dynamical regimes respectively.

Dynamics of emergent Cooper pairing at finite temperatures
We study the time evolution of a system of fermions with pairing interactions at a finite temperature. The dynamics is triggered by an abrupt increase in the BCS coupling constant. We show that if initially the fermions are in a normal phase, the amplitude of the BCS order parameter averaged over the Boltzmann distribution of initial states exhibits damped oscillations with a relatively short d...
متن کاملMolecular probe of pairing in the BEC-BCS crossover.
We have used optical molecular spectroscopy to probe the many-body state of paired 6Li atoms near a broad Feshbach resonance. The optical probe projects pairs of atoms onto a vibrational level of an excited molecule. The rate of excitation enables a precise measurement of the closed-channel contribution to the paired state. This contribution is found to be quite small, supporting the concept of...
متن کاملSolution for the dynamics of the BCS and central spin problems
We develop an explicit description of a time-dependent response of fermionic condensates to perturbations. The dynamics of Cooper pairs at times shorter than the energy relaxation time can be described by the BCS model. We obtain a general explicit solution for the dynamics of the BCS model. We also solve a closely related dynamical problem—the central spin model, which describes a localized sp...

To understand the mechanism of superconductivity in unconventional super onductors is one of the big challenges in the field of superconductivity. Based on the BCS theory, there is a direct relation between the pairing mechanism and the symmetry of the order parameter. Therefore, identification of the structure of the superconducting gap or the order parameter provides key information on the pa...

The recently discovered MgB2 superconductors have a record transition temperature for a BCS superconductor due to the high vibration frequencies associated with its light elements. The transition temperatures in the cuprate family of superconductors are much higher but these do not fit the BCS paradigm. The most promising microscopic origin for their many anomalous properties lies in magnetic...
