Understanding how the combined geometric quantities of the curve and surface affect the quantum dynamics calls for an effective theory. Here, we delve into the effective Hamiltonian governing a quantum particle confined to a curve that lies on a curved surface. By categorizing the constraints, we derive the effective Hamiltonians for two distinct scenarios: one where the curve is encapsulated in the surface, and another where the curve is a narrow ridge on the surface. The surface’s geometry substantially influences the dynamics of the curve, with the gauge potential in the former case being proportional to the geodesic torsion, and the emerging surface geodesic potential in the latter case being determined by both the geodesic curvature and geodesic torsion. We apply both the Hamiltonians to model quantum dynamics in circles on a sphere and helices on a cylinder, analyzing how the effective potential varies with different geometric parameters.

This phenomenon arises from the system’s evolution being influenced by its previous interactions with the environment. To better understand these complex dynamics, various measures have been proposed, including those based on divisibility, quantum mutual information, and trace distance. Each of these measures provides a different perspective on the behavior of OQSs. Here, we introduce a novel approach to quantifying non-Markovianity by focusing on metrological non-classical correlations. This approach is based on a discord-like measure of quantum correlations for multi-component quantum systems known as local quantum Fisher information (LQFI), which was introduced in Kim et al. (2018). It is defined as the minimization of quantum Fisher information with respect to local observables and measurements. Thereby, we examine some examples to clarify the use of our metric by applying it to three different channels: the phase damping channel, the amplitude damping channel, and the depolarizing channel. In contrast to other approaches, this new metric focuses on correlated bipartite <span><math><mrow><mn>2</mn><mo>⊗</mo><mi>d</mi></mrow></math></span> systems, has a clear physical interpretation, and effectively captures the features of non-Markovianity. We demonstrate that the non-Markovian or Markovian evolution of an open correlated bipartite system corresponds to an increase or decrease, respectively, in the quantumness of the quantum state. This quantumness is quantified by the maximum of the measurement-induced Fisher information across all local von Neumann measurements. Compared to measuring non-Markovianity based on local quantum uncertainty – a measure of non-classical correlation of the discord type based on single observables – our results confirm that the nonmonotonic evolution of the LQFI reveals a higher degree of backflow of quantum information and is more robust than the corresponding measure based on quantum uncertainty.</div></div>","PeriodicalId":8249,"journal":{"name":"Annals of Physics","volume":"480 ","pages":"Article 170142"},"PeriodicalIF":3.0,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144596621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}
