Giant Nernst effect due to fluctuating cooper pairs in superconductors.
A theory of the fluctuation-induced Nernst effect is developed for a two-dimensional superconductor in a perpendicular magnetic field. First, we derive a simple phenomenological formula for the Nernst coefficient, which naturally explains the giant Nernst signal due to fluctuating Cooper pairs. The latter signal is shown to be large even far from the transition and may exceed by orders of magni...
متن کاملAdiabatic Quantum Computation with Cooper Pairs
We propose a new variant of the controlled-NOT quantum logic gate based on adiabatic level-crossing dynamics of the q-bits. The gate has a natural implementation in terms of the Cooper pair transport in arrays of small Josephson tunnel junctions. An important advantage of the adiabatic approach is that the gate dynamics is insensitive to the unavoidable spread of junction parameters @ 1998 Else...
متن کاملCosmic Strings and Cooper Pairs
It is shown that it is possible for bound fermions on a cosmic string to form a superconducting state. Due to the attractive force between them, particles moving in opposite directions along the string form bound pairs. This involves a similar mechanism to superconductivity in metals at low temperatures. The method of Gorkov is used to analyse the system. In contrast to the situation in metals,...

متن کاملComment on "Giant Nernst effect due to fluctuating Cooper pairs in superconductors".
A comment is made on a letter (Phys. Rev. Lett. 102, 067001) and a paper (Phys. Rev. B 83, 020506) regarding the correct expression of the thermal current vertex for Cooper pairs. In the Ginzburg-Landau (GL) theory [1, 2] the electronic current ~ J and the thermal current ~ J carried by fluctuating Cooper pairs (T > Tc) are given as ~ J = 2e ~ J, (1) and ~ J = ω ~ J, (2) in the limit of vanishi...
