Asymptotics for Beta-Splitting Trees via Homogeneous Fragmentations and Meromorphic Potential Theory
Yoana R. Chorbadzhiyska, Martin Minchev, Mladen Savov
Inspired by recent work of Aldous, Janson, and Pittel on the critical beta-splitting model, we study the full beta-splitting family for beta greater than minus two through a canoni…
Analytical determination of multi-time correlation functions in quantum chaotic systems
Yoana R. Chorbadzhiyska, Peter A. Ivanov, Charlie Nation
The time-dependence of multi-point observable correlation functions are essential quantities in analysis and simulation of quantum dynamics. Open quantum systems approaches utilize…
Some developments of exchangeable measure-valued Pólya sequences
Yoana R. Chorbadzhiyska, Hristo Sariev, Mladen Savov
Measure-valued Pólya sequences (MVPS) are processes whose dynamics are governed by generalized Pólya urn schemes with infinitely many colors. Assuming a general reinforcement rule,…
Onset of Quantum Thermalization in Jahn-Teller model
Yoana R. Chorbadzhiyska, Peter A. Ivanov
We investigate the onset of quantum thermalization in a system governed by the Jahn-Teller Hamiltonian which describes the interaction between a single spin and two bosonic modes.…
Random Matrix Theory Approach to Quantum Fisher Information in Quantum Many-Body Systems
Venelin P. Pavlov, Yoana R. Chorbadzhiyska, Charlie Nation +2
We theoretically investigate parameter quantum estimation in quantum chaotic systems. Our analysis is based on an effective description of non-integrable quantum systems in terms o…
