| 0:00:20 | after a whole inverting merman |
|---|
| 0:00:21 | it is known that there cannot be any sharp phase transition in the one we |
|---|
| 0:00:26 | system |
|---|
| 0:00:27 | then an interesting question is there |
|---|
| 0:00:29 | what should be the behavior of an array of aligned in weakly coupled superconducting data |
|---|
| 0:00:35 | layers |
|---|
| 0:00:39 | example of such a system is the five zero carbon yellow to me if i |
|---|
| 0:00:46 | possibly one d bundle can be obtained by the interaction between the nearest carbon being |
|---|
| 0:00:51 | able to |
|---|
| 0:00:57 | here is schematic view of the experimental sample the af i acted as the backbone |
|---|
| 0:01:03 | of the c n t |
|---|
| 0:01:04 | in our theoretical model |
|---|
| 0:01:06 | the c n t combined to be an aligner bundle and then the downloads connected |
|---|
| 0:01:12 | to beginning or made by the we josephs in coupling |
|---|
| 0:01:16 | the monte carlo simulation was based on the jeans burned land on model will algorithm |
|---|
| 0:01:22 | was used to because of the weakness of the josephs and coupling between the bundles |
|---|
| 0:01:29 | we first discuss the specific you |
|---|
| 0:01:35 | since the josephs an interaction is weak amplitude of the wave function is determined mainly |
|---|
| 0:01:41 | by the coupling inside the bundle |
|---|
| 0:01:43 | we have |
|---|
| 0:01:44 | in each simulation |
|---|
| 0:01:46 | only a single done belonging to be considered |
|---|
| 0:01:55 | in the figure |
|---|
| 0:01:56 | the specific universes temperature under different magnetic field we shown |
|---|
| 0:02:01 | as reference |
|---|
| 0:02:02 | experimental result was also presented |
|---|
| 0:02:08 | because of the josephs and coupling between the bundles is weak |
|---|
| 0:02:12 | in the phase order simulation |
|---|
| 0:02:14 | we fix the amplitude of each bundle which was obtained in the specific you simulation |
|---|
| 0:02:26 | the phase order was calculated by the presented formula |
|---|
| 0:02:30 | the results under different magnetic field is shown in the figure |
|---|
| 0:02:34 | it can be seen that the transfer temperature t c is question by the magnetic |
|---|
| 0:02:39 | field |
|---|
| 0:02:40 | this is agree with the experimental results |
|---|
| 0:02:43 | from the figure |
|---|
| 0:02:44 | we can also see that although the interaction between them down the list is weak |
|---|
| 0:02:50 | it plays an important role in the phase transition |
|---|
| 0:02:55 | this is the correlation function in xy plane under different temperature |
|---|
| 0:03:01 | it can be seen that |
|---|
| 0:03:02 | above tc correlation length decays exponentially but below tc decays according to what power low |
|---|
| 0:03:13 | this is the exact peak at transition feature |
|---|
| 0:03:20 | to verify the results |
|---|
| 0:03:22 | for the temperature around three |
|---|
| 0:03:24 | we don't a numerical fitting of correlation length versus t c |
|---|
| 0:03:32 | the appearance of coherence in the transverse plane should have a crunching affect on the |
|---|
| 0:03:37 | phase fluctuations along the z axis |
|---|
| 0:03:40 | as shown in figure |
|---|
| 0:03:42 | it is indeed happen twenty below the transfer temperature given the coupling between the bundles |
|---|
| 0:03:48 | is very weak |
|---|
| 0:03:52 | from |
|---|
| 0:03:52 | conclusion can be obtained is that |
|---|
| 0:03:55 | the system have transferred from the one d the three d |
|---|
| 0:04:01 | in summary |
|---|
| 0:04:02 | we shown in this paper that for the quasi one d system specific you is |
|---|
| 0:04:07 | mainly determined by the closet one d character but the transverse coupling between the bundles |
|---|
| 0:04:13 | plays an important role in the phase order by which |
|---|
| 0:04:18 | one d the three d crossover transition can happen |
