They found other interesting events, too, such as the Centauro type, in the same region of extremely high energy. Experimental reports were published so far about these findings/> and their theoretical implications were synthetically discussed in a special issue of Supplement of Prog. Theor. Phys. in 1973.2> Later on, the experimental accuracy has been improved, and still more events have been discovered.8> This issue also contains their report of recent experimental results. I discussed the meaning of the importance of these findings in Prog. Theor. Phys. Suppl. No. 54 (1973), and also in my pamphlet \"Opening door to new physics\" distributed together with it. Almost all research workers of the theory of elementary particles seem to consider that the gauge theory or \"the unified theory of all fundamental forces\" has been a recent success in the theory of elementary particles. \"New physics\" that I mean, however, does not indicate the sort of things such as quark, charm, colour, gluon, weak boson, and so on, because all these things are what were considered on inferences from the theories hitherto presented, ranging from Sakata's two meson theory up to the Sakata model, the Nagoya model and others, and are what have been assumed in order to reinforce these former theories. \"New physics\" is the one that is concerned with such things as H-,SHand UH-quanta, Centauro phenomena and the related events, which were not expected at all from the former theories. These phenomena at ultra high energies are entirely new, and are named \"new states of matter\" by C. M.","PeriodicalId":20614,"journal":{"name":"Progress of Theoretical Physics Supplement","volume":"76 1","pages":"224-242"},"PeriodicalIF":0.0,"publicationDate":"2013-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1143/PTPS.76.224","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64900223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, this theory is a toy model for four-dimensional gravity. Second, two-dimensional quantum gravity is the theory on the world-sheet of both “critical” as well as “non-critical” string theories. Some of our conclusions apply to these two more general situations. Since we would like to draw lessons from this simple theory, which are generic and valid in more complicated systems, we should study it in continuum field theory language. In these notes we review the status of the continuum Liouville approach to quantum gravity. Our understanding of the subject is far from complete. We will point out what we think are the most important open problems, and will speculate about their solutions.","PeriodicalId":20614,"journal":{"name":"Progress of Theoretical Physics Supplement","volume":"102 1","pages":"319-349"},"PeriodicalIF":0.0,"publicationDate":"2013-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1143/PTPS.102.319","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64706907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a three band model to describe the relevant surface band structure, the line width due to this surface Auger process is found to be about 8 times larger on the Ni(111) surface than on the Cu surface. This significant difference results from the difference in surface state occupancy. Comparison with recent experimental data from two photon photoemission demonstrates that these surface states are essential for the decay of the excited electron at surface","PeriodicalId":20614,"journal":{"name":"Progress of Theoretical Physics Supplement","volume":"106 1","pages":"405-410"},"PeriodicalIF":0.0,"publicationDate":"2013-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64714310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
