1. 1. An Exploration of Q-Systems : From Spin Chains to Low-Dimensional AdS/CFT

   Författare :Simon Ekhammar; Dmytro Volin; Konstantin Zarembo; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum Spectral Curve; Integrability; AdS CFT; Physics and Astronomy specializing in Theoretical Physics; Fysik och astronomi med inriktning mot teoretisk fysik;

   Sammanfattning : The discovery of integrability in the planar limit of the AdS5/CFT4 correspondence has led to impressive progress in the study of string theory and four-dimensional N=4 Super-Yang-Mills. In particular, with the formulation of the Quantum Spectral Curve (QSC) the spectral problem is now solved. LÄS MER

3. 2. On string integrability : A journey through the two-dimensional hidden symmetries in the AdS/CFT dualities

   Författare :Valentina Giangreco Marotta Puletti; Konstantin Zarembo; Gleb Arutyunov; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; String Theory; AdS-CFT correspondence; Integrable Field theory; Sigma models; S-matrix; Factorized Scattering; Physics; Fysik; Mathematical physics; Matematisk fysik; Theoretical Physics; teoretisk fysik;

   Sammanfattning : One of the main topics in the modern String Theory are the conjectured string/gauge (AdS/CFT) dualities. Proving such conjectures is extremely difficult since the gauge and string theory perturbative regimes do not overlap. In this perspective, the discovery of infinitely many conserved charges, i.e. LÄS MER

4. 3. Exact Results in Supersymmetric Field Theories : A dissertation on the defect and deformed

   Författare :Erik Widen; Konstantin Zarembo; Nikolay Gromov; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AdS CFT correspondence; integrability; localization; supersymmetric deformations; Quantum Spectral Curve; defect CFT; one-point functions; Theoretical Physics; Teoretisk fysik;

   Sammanfattning : Quantum field theories (QFTs) are the most precise descriptions of the physical reality that humanity has found. Yet exact predictions are often missing as most computations are notoriously difficult to carry out. One generally resorts to perturbation theory which immediately limits the regime of validity.

5. 4. Emergent spacetime from simple field theories

   Författare :Julius Engelsöy; Bo Sundborg; Sumit R. Das; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AdS CFT; thermalization; quench; large N singlet models; emergent spacetime; fysik; Physics;

   Sammanfattning : Thermalization is an elusive phenomenon in quantum mechanics. Since according to the AdS/CFT correspondence, a black hole in the bulk spacetime is dual to a thermal state in the boundary CFT, thermalization in the CFT is dual to black hole formation in AdS. LÄS MER

7. 5. Topics on D-branes and Holography

   Författare :Mikael Smedbäck; Joseph Minahan; Anton Alekseev; Paolo Di Vecchia; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; theoretical physics; string theory; D-branes; dualities; AdS CFT; spin chains; Bethe ansatz; boundary conformal field theory; conformal bootstrap; tachyon condensation; string field theory; loop quantum gravity; black holes; area spectrum; Hawking radiation; holographic principle; Teoretisk fysik; Physics; Fysik;

   Sammanfattning : We discuss various aspects of D-branes in string theory and holography in string theory and loop quantum gravity.One way to study D-branes is from a microscopic perspective, using conformal field theory techniques. For example, we investigate the question of how D-branes can be introduced into orbifolded theories. LÄS MER
