1. 21. Exactly solved quantum many-body systems in one dimension

   Författare :Martin Hallnäs; Edwin Langmann; Stefan Rauch-Wojciechowski; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Sammanfattning : This thesis is devoted to the study of various examples of exactly solved quantum many-body systems in one-dimension. It is divided into two parts: the first provides background and complementary results to the second, which consists of three scientific papers. LÄS MER

3. 22. Dynamics of open fermionic nano-systems -- a fundamental symmetry and its application to electron transport in interacting quantum dots

   Författare :Jens Schulenborg; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fermion parity; voltage switch; quantum dot; open fermionic quantum system; fermionic duality; master equation; non-equilibrium transport; charging energy; inverted energy; transient response; energy-dependent coupling;

   Sammanfattning : The study of electronic transport through strongly confined, interacting open quantum systems has regained considerable interest over the past years. One main motivation behind this concerns the possibility of time-dependently controlled operations on individual electrons, promising applications in, e.g. LÄS MER

4. 23. The Shape of Strangeness: Transverse Spherocity and Underlying Event studies of φ and its relation to Ξ in √s = 13 TeV pp collisions

   Författare :Adrian Nassirpour; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LHC; ALICE; Quark-Gluon Plasma; small systems; pp collisions; underlying event; event-shape engineering; transverse activity; strangeness enhancement; resonance production; Fysicumarkivet A:2022:Nassirpour;

   Sammanfattning : Through ultrarelativistic particle collisions at the LHC, it is possible to deconfine quarks and gluons. This deconfinement gives rise to a strongly interacting medium, referred to as the Quark-Gluon Plasma (QGP). LÄS MER

5. 24. Study of Ξ-Hadron Correlations in pp Collisions at √s = 13 TeV Using the ALICE Detector

   Författare :Jonatan Adolfsson; Fysiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LHC; ALICE; quark gluon plasma; small systems; pp collisions; strangeness enhancement; correlations;

   Sammanfattning : By colliding heavy nuclei at high energies, which is done at RHIC and the LHC, a strongly interacting Quark Gluon Plasma (QGP) is created. This manifests itself through several different signatures, which until recently was thought to uniquely probe the QGP. LÄS MER

7. 25. Trends in Magnetism : From Strong Correlations to “-onics” Technology

   Författare :Dmitry Yudin; Olle Eriksson; Grigori Volovik; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Strongly interacting electron systems; Spin dynamics; Topological matter; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : Despite of enormous progress in experimental nanophysics theoretical studies of low-dimensional electron systems still remains a challenging task. Indeed, most of the structures are strongly correlated, so that an effective perturbative treatment is impossible due to the lack of a small parameter. LÄS MER
