Quantization of pure gravitational plane waves [PDF]
, 1998 Pure gravitational plane waves are considered as a special case of spacetimes with two commuting spacelike Killing vector fields. Starting with a midisuperspace that describes this kind of spacetimes, we introduce gauge-fixing and symmetry conditions ...

Advanced Optical Materials, EarlyView.Combining high‐order cluster‐correlation expansion with experiment, it is revealed that P1‐driven NV decoherence under dynamical decoupling deviates from semi‐classical scaling laws. The coherence‐time exponent depends on pulse number and bath conditions, demonstrating the necessity of a full quantum bath description.

KAM--renormalization-group for Hamiltonian systems with two degrees of freedom
, 1998 We review a formulation of a renormalization-group scheme for Hamiltonian systems with two degrees of freedom. We discuss the renormalization flow on the basis of the continued fraction expansion of the frequency. The goal of this approach is to understand universal scaling behavior of critical invariant tori.

On numerical bifurcation analysis of periodic motions of autonomous Hamiltonian systems with two degrees of freedom [PDF]
Journal of Physics: Conference Series, 2021 Abstract In this work we consider bifurcation problem for natural families of periodic motions of autonomous Hamiltonian systems with two degrees of freedom. While there exists a well-developed analytical approach to this problem, it is limited to small neighborhoods of known equilibria and stationary solutions.

Advanced Science, EarlyView.We combine altermagnet with topological insulators and subject the structure to Floquet driving. This breaks time‐reversal symmetry and creates a new type of higher‐order topological insulator. Its key feature is the emergence of programmable “0/π‐corner modes” that can be controlled by magnetic field direction, offering a novel dynamic platform for ...

On the dynamics of spring-pendulum system: an overview of configuration space and phase space
Jurnal NaturalThe dynamics of the spring-pendulum system with two degrees of freedom were studied. The motion of this system is restricted to be in a vertical plane so that the chosen generalized coordinates are the increased length of the spring and the swing angle ...
