Supercritical CO2 synthesis of LaAlO3/SrTiO3 heterostructures with tunable room-temperature ferromagnetism Yonglong Zhu [1], Qun Xu* [1] https://www.academia.edu/3064-979X/3/2/10.20935/AcadQuant8304 Introduction: Two-dimensional magnets hold great promise for spintronic applications, and LaAlO3/SrTiO3 heterostructures provide an important platform for exploring emergent interfacial magnetic phenomena. Traditional fabrication methods such as pulsed laser deposition suffer from high vacuum requirements, high cost, and operational complexity, which limit their widespread use. https://www.academia.edu/journals/academia-quantum/articles?source=journal-top-nav

The continuous spectrum of bound states in expulsive potentials: self-trapping in the linear system Hidetsugu Sakaguchi [1], Boris A. Malomed* [2]ORCID iD, Andreas C. Aristotelous [3], Efstathios G. Charalampidis [4] https://www.academia.edu/3064-979X/3/2/10.20935/AcadQuant8294 Introduction: Contrary to common intuition, which suggests that a steep expulsive potential makes quantum states widely delocalized, we demonstrate that one- and two-dimensional (1D and 2D) Schrödinger equations, which include expulsive potentials that are steeper than the quadratic ones, give rise to normalizable eigenstates, which may be considered as a manifestation of effective self-trapping in the linear system. https://www.academia.edu/journals/academia-quantum/articles?source=journal-top-nav

A graph-based quantum-inspired approximation of the Feynman path integral Barbara Collignon* [1]

https://www.academia.edu/3064-979X/3/2/10.20935/AcadQuant8290 Introduction: We introduce a novel quantum-inspired simulator that approximates the Feynman path integral within a discrete, graph-theoretic framework, mapping logical qubits to graph vertices. https://www.academia.edu/journals/academia-quantum/articles?source=journal-top-nav

Bell’s concept of local causality does not preclude Bell correlations in local realist field ontologies Andrew Laidlaw* [1]

Bell’s concept of local causality does not preclude Bell correlations in local realist field ontologies Andrew Laidlaw* [1] https://www.academia.edu/3064-979X/3/2/10.20935/AcadQuant8384 Introduction: Bell’s concept of local causality assumes more than local action. It also presumes an ontology of point particles. Bell correlations are feasible in nonlinear field ontologies with quantised interactions between suitably correlated participants. https://www.academia.edu/journals/academia-quantum/articles?source=journal-top-nav

Quantum detection of microwave and terahertz signals using Rydberg EIT/EIA spectroscopy Gennady A. Koganov* [1] , Reuben Shuker [1]

https://www.academia.edu/3064-979X/3/1/10.20935/AcadQuant8222 Introduction: Quantum light–matter interaction provides an excellent application of Rydberg levels. Rydberg states are special in the sense that they have a long lifetime and large dipole moments. The large number of these levels and the spacing among them enable the detection of the incoming signals in the broad region of the electromagnetic spectrum, encompassing microwave (MW), terahertz (THz) and radio frequency (RF) ranges. Electromagnetically Induced Absorption (EIA) and Transparency (EIT) can be achieved at these levels. MW and THz signals can quantum-mechanically split the relevant spectral lines in which the splitting is proportional to the strength of an incoming em field. https://www.academia.edu/journals/academia-quantum/articles?source=journal-top-nav

Descubren cómo son los sistemas volcánicos del interior de Marte

Descubren cómo son los sistemas volcánicos del interior de Marte Los expertos pensaban que el planeta rojo poseía un vulcanismo mucho más simple que el de la Tierra al carecer de tectónica de placas, pero un nuevo estudio sugiere que tuvo una corteza igual de compleja, lo que pudo influir en la formación de una atmósfera y en su habitabilidad. https://www.agenciasinc.es/Noticias/Descubren-como-son-los-sistemas-volcanicos-del-interior-de-Marte

Más allá del límite: un millón de satélites y espejos amenazan la oscuridad del cielo nocturno

Más allá del límite: un millón de satélites y espejos amenazan la oscuridad del cielo nocturno Un estudio del Observatorio Europeo Austral concluye que las propuestas actuales para lanzar más de 1,7 millones de satélites tendrían consecuencias devastadoras para la astronomía. Según sus cálculos, la cifra no debería superar los 100 000, siempre que sean invisibles a simple vista, para preservar las observaciones con telescopios modernos. https://www.agenciasinc.es/Noticias/Mas-alla-del-limite-un-millon-de-satelites-y-espejos-amenazan-la-oscuridad-del-cielo-nocturno
