Local correlations in long-range dual-unitary kicked Hamiltonian chains
Vladimir Al. Osipov, Marc Cedric Spyra, Jana Carolina Schumann +2
Many-body Floquet models with exact space--time symmetry, such as the kicked Ising spin chain (KIC), provide natural examples of systems with dual-unitary dynamics. The requirement…
Stability of the Quantum Coherent Superradiant States in Relation to Exciton-Phonon Interactions and the Fundamental Soliton in Hybrid Perovskites
A. A. Gladkij, N. A. Veretenov, N. N. Rosanov +3
The use of macroscopic coherent quantum states at room temperature is crucial in modern quantum technologies. In light of recent experiments demonstrating high-temperature superflu…
Local correlations in partially dual-unitary lattice models
Vladimir Al. Osipov, Niclas Krieger, Thomas Guhr +1
We consider the problem of local correlations in the kicked, dual-unitary coupled maps on D-dimensional lattices. We demonstrate that for D>=2, fully dual-unitary systems exhibit u…
Hartree method for molecular polaritons
Vladimir Al. Osipov, Boris Fainberg
The formation of the composite photonic-excitonic particle, known as a polariton, is a phenomenon emerging in materials possessing strong coupling to light. The organic-based mater…
Power Spectrum of Long Eigenlevel Sequences in Quantum Chaotic Systems
Roman Riser, Vladimir Al. Osipov, Eugene Kanzieper
We present a non-perturbative analysis of the power-spectrum of energy level fluctuations in fully chaotic quantum structures. Focussing on systems with broken time-reversal symmet…
The nature of relaxation processes revealed by the action signals of phase modulated light fields
Vladimir Al. Osipov, Xiuyin Shang, Thorsten Hansen +2
We introduce a generalized theoretical approach to study action signals induced by the absorption of two-photons from two phase modulated laser beams and subject it to experimental…
Wavelet analysis on symbolic sequences and two-fold de Bruijn sequences
Vladimir Al. Osipov
The concept of symbolic sequences play important role in study of complex systems. In the work we are interested in ultrametric structure of the set of cyclic sequences naturally a…
Fluorescence correlation spectroscopy in thin films at reflecting substrates as a means to study nanoscale structure and dynamics at soft-matter interfaces
Daniela Täuber, Kathrin Radscheit, Vladimir Al. Osipov +2
Structure and dynamics at soft-matter interfaces play an important role in nature and technical applications. Optical single-molecule investigations are non-invasive and capable to…
Classical foundations of many-particle quantum chaos
Boris Gutkin, Vladimir Osipov
In the framework of semiclassical theory the universal properties of quantum systems with classically chaotic dynamics can be accounted for through correlations between partner per…
Universality in spectral statistics of "open" quantum graphs
Boris Gutkin, Vladimir Al. Osipov
The unitary evolution maps in closed chaotic quantum graphs are known to have universal spectral correlations, as predicted by random matrix theory. In chaotic graphs with absorpti…
Clustering of periodic orbits and ensembles of truncated unitary matrices
Boris Gutkin, Vladimir Al. Osipov
Periodic orbits in chaotic systems form clusters, whose elements traverse approximately the same points of the phase space. The distribution of cluster sizes depends on the length…
Counting of Sieber-Richter pairs of periodic orbits
Boris Gutkin, Vladimir Al. Osipov
In the framework of the semiclassical approach the universal spectral correlations in the Hamiltonian systems with classical chaotic dynamics can be attributed to the systematic co…
Electronic properties of disclinated flexible membrane beyond the inextensional limit: Application to graphene
E. A. Kochetov, V. A. Osipov, R. Pincak
Gauge-theory approach to describe Dirac fermions on a disclinated flexible membrane beyond the inextensional limit is formulated. The elastic membrane is considered as an embedding…
Correlations of RMT Characteristic Polynomials and Integrability: Hermitean Matrices
Vladimir Al. Osipov, Eugene Kanzieper
Integrable theory is formulated for correlation functions of characteristic polynomials associated with invariant non-Gaussian ensembles of Hermitean random matrices. By embedding…
Random Bures mixed states and the distribution of their purity
Vladimir Al. Osipov, Hans-Juergen Sommers, Karol Zyczkowski
Ensembles of random density matrices determined by various probability measures are analysed. A simple and efficient algorithm to generate at random density matrices distributed ac…
p-Adic Models of Ultrametric Diffusion Constrained by Hierarchical Energy Landscapes
V A Avetisov, A H Bikulov, S V Kozyrev +1
We demonstrate that p-adic analysis is a natural basis for the construction of a wide variety of the ultrametric diffusion models constrained by hierarchical energy landscapes. A g…
