(English) Quantum many-body physics poses a substantial computational challenge resulting from the exponential growth of the wave function complexity and many non-trivial correlations encoded in it. ...
Kottmann, Korbinian Gebhard (Date of defense: 2022-10-14)
(English) We perform quantum simulation on classical and quantum computers and set up a machine learning framework in which we can map out phase diagrams of known and unknown quantum many-body systems ...
Guenther, Nils Eric (Date of defense: 2021-09-08)
At sufficiently low temperatures, fluids of bosonic particles may undergo a phase transition, below which a Bose-Einstein condensate (BEC) forms. The BEC is one of the most fundamental concepts in ...
González Cuadra, Daniel (Date of defense: 2020-12-11)
The outstanding progress achieved in the last decades to isolate and manipulate individual quantum systems has revolutionized the way in which quantum many-body phenomena, appearing across Nature's ...
Julià Farré, Sergi (Date of defense: 2022-06-28)
The last decades have witnessed impressive technical advances in all the fields of quantum science, including solid-state systems or atomic, molecular, and optical physics, allowing one to control ...
Aloy López, Albert (Date of defense: 2020-07-16)
Entanglement and non-local correlations give rise to unprecedented phenomena with no classical analogue. As a result, they have settled themselves as fundamental properties in the study of quantum ...
Charalambous, Christos (Date of defense: 2020-01-31)
Quantum Brownian motion is one of the most prominent examples of an open quantum system, a system which cannot be treated in isolation from its environment. The simplest method to study the dynamics of ...
Almeida, Jessica Oliveira de (Date of defense: 2022-07-28)
Quantum optics experiments are currently the most advanced techniques to under- stand, verify and simulate quantum phenomena. However, to access all the perfor- mance available in quantum states of ...
Muñoz Gil, Gorka (Date of defense: 2020-11-09)
Diffusion refers to numerous phenomena, by which particles and bodies of all kinds move throughout any kind of material, has emerged as one of the most prominent subjects in the study of complex systems. ...
