However, existing studies on the dynamical behaviors of multi-homoclinic orbits and inter-well motions in multistable systems remain insufficient. A spring-coupled rotational inverted pendulum system (SRIP) was established by combining an inverted pendulum and a two-dimensional planar oscillator, enabling the structural multi-stability and homoclinic orbit characteristics to be modulated through parameter adjustments. The equations of motion for both the single-degree-of-freedom(SDOF) and the two-degree-of-freedom(2DOF) SRIP system were derived using Lagrange’s equations. The chaotic response characteristics were then analyzed via the energy and Melnikov functions of homoclinic orbits. The contour plots of energy function for the SDOF SRIP system characterize the topological structures of its phase plane, while the bifurcation characteristics of equilibrium points were examined by analyzing the stability of local extrema in the potential function. Homoclinic bifurcations were depicted by the contours corresponding to the energy levels of unstable equilibrium points. For the 2DOF system, dimensional reduction was performed, and a semi-analytical approach combining Melnikov functions was applied to evaluate the oriented distances between stable and unstable manifolds of various types of homoclinic orbits, thereby characterizing the chaotic responses under perturbations. Numerical simulations validated the analytical results. With increasing coupling stiffness, pitchfork bifurcations of equilibrium points and homoclinic-heteroclinic bifurcations emerge.

Electroosmosis is a fundamental phenomenon that enables the controlled flow of ionic solutions in response to an external electric field, thereby amplifying the pumping flow rate. This study presents an unsteady viscous flow of the Carreau fluid model, whose rheological properties are similar to those of blood in a microchannel, subjected to periodic membrane pumping along with heat transfer.

The perturbation series solution method is employed to solve the transformed, dimensionless governing equations together with the corresponding boundary conditions, and the results are presented graphically. The plotted results illustrate that the kinematics of membrane motion generate the transmural pressure, which is controlled by the velocity slip parameter and rheological properties of the fluid.

On the other hand, large-scale qutrit-based hybrid quantum computing usually requires performing hybrid multi-qutrit quantum gates with diverse qutrits, different in their nature or in their encoding format. In this work, we consider two types of qutrits, i.e., superconducting (SC) qutrits and cat-state qutrits. We propose to implement a hybrid controlled-SUM gate with one SC qutrit simultaneously controlling multiple-target cat-state qutrits. The gate is implemented in a circuit-QED system, which is composed of an SC ququart and multiple microwave cavities. The SC ququart here refers to a four-level quantum system, with the three lowest levels forming a qutrit and an auxiliary higher energy level utilized for the coherent state manipulation. The gate implementation does not require applying a classical pulse. Because the auxiliary higher energy level of the SC ququart is only virtually excited during the gate operation, decoherence from this level is greatly suppressed. The gate is deterministic, as it requires no measurement of the cavity or SC ququart states. Moreover, the gate operational time is independent of the number of qutrits, thus it does not increase with the number of qutrits. As an application of this gate, we further discuss the generation of a hybrid maximally entangled state of one SC qutrit and multiple cat-state qutrits. We also numerically analyze the experimental feasibility of creating the hybrid entangled state of one SC qutrit and two cat-state qutrits in a circuit QED system. This proposal may be extended to accomplish the same task in other physical systems, such as a four-level artificial atom (e.g., a quantum dot, an NV center, a magnon, etc.) coupled to multiple optical or microwave cavities.</div></div>","PeriodicalId":10340,"journal":{"name":"Chinese Journal of Physics","volume":"99 ","pages":"Pages 266-282"},"PeriodicalIF":4.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145837438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
