Address / Location
START Fellowship Interview Day
START Fellowship candidates are invited to present their research proposals and for interviews. This also gives them the opportunity to discover the research environment in Munich and to get to know the MCQST community.
As first part of the program, the candidates will introduce themselves, present their previous work as well as their research proposal for their START projects. In the afternoon, the program continues with interviews in closed sessions.
All talks are open to the entire MCQST community.
09:00 | Welcome words by Professor Ignacio Cirac, MPQ
09:10 | Marko Ljubotina from ISTA, Austria - "Anomalous transport in kinetically constrained models"
Universal nonequilibrium properties of isolated quantum systems are typically probed by studying transport of conserved quantities. Significant progress has been made in this direction in recent years, particularly in regard to the anomalous transport discovered in some integrable systems. In this talk I will describe some recent results in kinetically constrained systems that demonstrate anomalous superdiffusive transport can also appear in chaotic quantum systems. Specifically, we have observed superdiffusive dynamics of energy in the PXP model and even ballistic dynamics of some states in a chaotic constrained hopping model.These results are sharp contract to the common intuition of dynamics in chaotic models and call for additional studies to attempt to understand the underlying properties that can give rise to the observed behaviours.
09:35 | Farsane Tabataba-Vakili from LMU Munich- "Towards moiré quantum magnets and moiré magneto-polaritons"
Moiré effects in twisted two-dimensional materials give rise to new and emergent quantum many-body physics, with demonstrations of superconductivity in twisted bilayer graphene, Wigner crystal and Mott insulator states in twisted bilayers of transition metal dichalcogenides, and moiré magnetism in twisted few-layer CrI3. The magnetic semiconductor CrSBr offers a unique platform for exploring moiré quantum magnetism and moiré magneto-polaritons, due to its correlated excitonic and magnetic properties. In this talk, I will discuss the three building blocks needed to realize the proposed project: the moiré superlattice, the magnetic semiconductor, and polariton microcavities, which are all related to expertise I gained in prior projects as a postdoc.
10:00 | Miguel Bello Gamboa from MPI of Quantum Optics - "Quantum Impurity Models in the XXI Century: Opportunities and Challenges"
Quantum impurity models have driven many of the advances in theoretical physics in recent years. Fundamental techniques such as the Schrieffer-Wolff transformation or the numerical renormalization group technique emerged from the study of impurity problems. Although this is an old topic, current experimental capabilities allow us to study these models in unprecedented detail and to ask questions that could not be answered before. In this talk, I will review some of the work that I and my collaborators have done in this area, especially in the context of quantum optics, and discuss some of the open problems that I want to tackle in the near future.
10:25 | Coffee Break
10:40 | Gianmarco Gatti from Université de Genève - "Accessing moiré physics in the electronic structure of atomic bilayers"
Moiré systems emerged as versatile platforms to investigate quantum many-body phenomena. Nevertheless, the nature of the experimentally reported correlated phases is still under debate. In this talk, I will present novel results from angle-resolved photoemission experiments that reveal signatures of moiré physics affecting the quasiparticle dispersion in semiconducting bilayers. Our methodology sets the pathway towards a deeper understanding of correlations in two dimensions.
11:05 | Benjamin Lienhard from Princeton University - "Interfacing with Quantum Information Processors—From Readout to Control"
Achieving the vision of practical quantum computing hinges on striking a delicate balance in managing the complexities of quantum system control, especially concerning measurements during system characterization, calibration, and correction. In this presentation, I will introduce protocols we have developed to improve superconducting qubit readout through machine learning. Additionally, I will discuss our approach to scalable quantum processor calibration and the potential for designing quantum control with inherent or engineered robustness to noise.
11:30 | Simone Rademacher from LMU Munich- "Mathematical analysis of interacting quantum systems"
In this talk I will give an overview of my career and my field of research, the mathematical analysis of interacting many-body quantum systems. At the microscopic level, many-body systems are completely described by the basic principles of quantum mechanics. Due to the large number of interacting particles, the microscopic description is hardly accessible for calculations. For this reason, my goal is to develop new techniques to derive mathematically rigorous macroscopic descriptions of the collective behavior of individual particles such as phase transitions, effective mass or effective dynamics.
