Whereas for bosons a point interacting system is always unstable this ques- tion is more subtle for a gas of two species of fermions. In particular the answer depends on the mass ratio between these two species. Most of this work will be focused on the N + M model which consists of two species of fermions with N, M particles respectively which interact via point interactions. We will introduce this model using a formal limit and discuss the N + 1 system in more detail. In particular, we will show that for mass ratios above a critical one, which does not depend on the particle number, the N + 1 system is stable. In the context of this model we will prove rigorous versions of Tan relations which relate various quantities of the point-interacting model. By restricting the N + 1 system to a box we define a finite density model with point in- teractions. In the context of this system we will discuss the energy change when introducing a point-interacting impurity into a system of non-interacting fermions. We will see that this change in energy is bounded independently of the particle number and in particular the bound only depends on the density and the scattering length. As another special case of the N + M model we will show stability of the 2 + 2 model for mass ratios in an interval around one. Further we will investigate a different model of point interactions which was discussed before in the literature and which is, contrary to the N + M model, not given by a limiting procedure but is based on a Dirichlet form. We will show that this system behaves trivially in the thermodynamic limit, i.e. the free energy per particle is the same as the one of the non-interacting system."}],"has_accepted_license":"1"},{"year":"2018","isi":1,"external_id":{"isi":["000439639700001"]},"related_material":{"record":[{"status":"public","relation":"dissertation_contains","id":"52"}]},"publist_id":"7767","project":[{"_id":"25C6DC12-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"694227","name":"Analysis of quantum many-body systems"},{"call_identifier":"FWF","name":"Structure of the Excitation Spectrum for Many-Body Quantum Systems","grant_number":"P27533_N27","_id":"25C878CE-B435-11E9-9278-68D0E5697425"},{"_id":"3AC91DDA-15DF-11EA-824D-93A3E7B544D1","call_identifier":"FWF","name":"FWF Open Access Fund"}],"publication":"Mathematical Physics Analysis and Geometry","status":"public","ec_funded":1,"date_published":"2018-09-01T00:00:00Z","acknowledgement":"Open access funding provided by Austrian Science Fund (FWF).","doi":"10.1007/s11040-018-9275-3","article_processing_charge":"No","publisher":"Springer","date_updated":"2023-09-19T09:31:15Z","_id":"154","type":"journal_article","ddc":["530"],"quality_controlled":"1","month":"09","department":[{"_id":"RoSe"}],"article_number":"19","file":[{"date_updated":"2020-07-14T12:45:01Z","creator":"dernst","date_created":"2018-12-17T16:49:02Z","file_size":496973,"file_id":"5729","content_type":"application/pdf","access_level":"open_access","file_name":"2018_MathPhysics_Moser.pdf","checksum":"411c4db5700d7297c9cd8ebc5dd29091","relation":"main_file"}],"oa":1,"language":[{"iso":"eng"}],"issue":"3","citation":{"mla":"Moser, Thomas, and Robert Seiringer. “Stability of the 2+2 Fermionic System with Point Interactions.” <i>Mathematical Physics Analysis and Geometry</i>, vol. 21, no. 3, 19, Springer, 2018, doi:<a href=\"https://doi.org/10.1007/s11040-018-9275-3\">10.1007/s11040-018-9275-3</a>.","apa":"Moser, T., &#38; Seiringer, R.

While for two particles the interaction corresponds to infinite scattering length, the presence of further particles effectively decreases the interaction strength. We show that the model becomes trivial in the thermodynamic limit, in the sense that the free energy density at any given particle density and temperature agrees with the corresponding expression for non-interacting particles.","lang":"eng"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"intvolume":"       107","has_accepted_license":"1","date_created":"2018-12-11T11:50:40Z","volume":107,"title":"Triviality of a model of particles with point interactions in the thermodynamic limit","oa_version":"Published Version","scopus_import":"1","day":"01","author":[{"first_name":"Thomas","last_name":"Moser","id":"2B5FC9A4-F248-11E8-B48F-1D18A9856A87","full_name":"Moser, Thomas"},{"full_name":"Seiringer, Robert","id":"4AFD0470-F248-11E8-B48F-1D18A9856A87","last_name":"Seiringer","orcid":"0000-0002-6781-0521","first_name":"Robert"}]},{"type":"conference","_id":"1428","date_updated":"2021-01-12T06:50:40Z","publisher":"IOP Publishing Ltd.","doi":"10.1088/1742-6596/691/1/012016","quality_controlled":"1","ddc":["510","530"],"publist_id":"5770","year":"2016","date_published":"2016-03-07T00:00:00Z","conference":{"location":"Shanghai, China","start_date":"2015-08-21","end_date":"2015-08-25","name":"24th International Laser Physics Workshop (LPHYS'15)"},"status":"public","publication":"Journal of Physics: Conference Series","project":[{"grant_number":"P27533_N27","name":"Structure of the Excitation Spectrum for Many-Body Quantum Systems","call_identifier":"FWF","_id":"25C878CE-B435-11E9-9278-68D0E5697425"}],"date_created":"2018-12-11T11:51:58Z","volume":691,"title":"Superfluidity and BEC in a Model of Interacting Bosons in a Random Potential","oa_version":"Published Version","day":"07","scopus_import":1,"author":[{"full_name":"Könenberg, Martin","last_name":"Könenberg","first_name":"Martin"},{"full_name":"Moser, Thomas","id":"2B5FC9A4-F248-11E8-B48F-1D18A9856A87","last_name":"Moser","first_name":"Thomas"},{"orcid":"0000-0002-6781-0521","first_name":"Robert","last_name":"Seiringer","id":"4AFD0470-F248-11E8-B48F-1D18A9856A87","full_name":"Seiringer, Robert"},{"last_name":"Yngvason","full_name":"Yngvason, Jakob","first_name":"Jakob"}],"file_date_updated":"2020-07-14T12:44:53Z","publication_status":"published","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"intvolume":"       691","abstract":[{"text":"We report on a mathematically rigorous analysis of the superfluid properties of a Bose- Einstein condensate in the many-body ground state of a one-dimensional model of interacting bosons in a random potential.","lang":"eng"}],"has_accepted_license":"1","file":[{"relation":"main_file","checksum":"109db801749072c3f6c8f1a1848700fa","file_name":"IST-2016-585-v1+1_JPCS_691_1_012016.pdf","content_type":"application/pdf","access_level":"open_access","file_id":"4847","file_size":1434688,"date_created":"2018-12-12T10:10:55Z","creator":"system","date_updated":"2020-07-14T12:44:53Z"}],"article_number":"012016","department":[{"_id":"RoSe"}],"month":"03","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","citation":{"ama":"Könenberg M, Moser T, Seiringer R, Yngvason J.
