Investigating CP Violating Majorana Phases of Neutrinos
Authors: Lisha  , Mahajan Neelu 
Published: December 2023

Abstract
Pontecorvo-Maki-Nakagawa-Sakata (PMNS) matrix is a complex symmetric matrix consisting of three generations of neutrinos and 12 real parameters. Diagonalizing the neutrino mass matrix and expressing the same in terms of three neutrino masses, three mixing angles, one Dirac phase and two Majorana phases such that it removes all the unphysical phases. The absolute neutrino mass scale and two Majorana CP-violating phases cannot be determined by neutrino oscillation experiments and hence an attempt has been made to investigate Majorana phases by drawing a correlation between the elements of neutrino mass matrix under the conditions of simultaneity and equated them to zero. We obtain twenty-five neutrino mass matrix textures for inverted hierarchy of Majorana neutrinos. Finally, numerical values of Majorana phases have been calculated for these textures and other phenomenological quantities are in consistent with the oscillation data.

Abstract

‘The Stopping and Range of Ions in Matter’ SRIM program, utilizing the built-in compound directory has been used to compute Bragg curve, projected range, longitudinal, lateral straggle of 12C ion with energies of 1 − 150 MeV in biological matter: liquid water (benchmark) human blood, skin, thyroid, and spleen are assessed. Results show that in the studied biological media for higher energy beam i): noticeable modification are seen in Bragg peak, shift in peak-position; ii) maximum projected range: 595.2 μm suggests effective use of 12C ions for cancer tumor therapy, especially for superficial cancer tumors, without much damage to healthier cells; iii) longitudinal straggling ~ 22.6 μm, low lateral straggling ~ 4.7 μm suggests potential application of 12C ions in treating cancer tumor nearby critical organs, causing minimal damage in nearby normal tissues.
Real-time gesture-based control of UAVs using multimodal fusion of FMCW radar and vision
Authors: Yang Lewei 
Published: December 2023

Abstract
Gesture-based control has gained prominence as an intuitive and natural means of interaction with unmanned aerial vehicles (UAVs). This paper presents a real-time gesture-based control system for UAVs that leverages the multimodal fusion of Frequency Modulated Continuous Wave (FMCW) radar and vision sensors, aiming to enhance user experience through precise and responsive UAV control via hand gestures. The research focuses on developing an effective fusion framework that combines the complementary advantages of FMCW radar and vision sensors. FMCW radar provides robust range and velocity measurements, while vision sensors capture fine-grained visual information. By integrating data from these modalities, the system achieves a comprehensive understanding of hand gestures, resulting in improved gesture recognition accuracy and robustness. The proposed system comprises three main stages: data acquisition, gesture recognition, and multimodal fusion. In the data acquisition stage, synchronized data streams from FMCW radar and vision sensors are captured. Then, machine learning algorithms are employed in the gesture recognition stage to classify and interpret hand gestures. Finally, the multimodal fusion stage aligns and fuses the data, creating a unified representation that captures the spatial and temporal aspects of hand gestures, enabling real-time control commands for the UAV. Experimental results demonstrate the system‘s effectiveness in accurately recognizing and responding to hand gestures. The multimodal fusion of FMCW radar and vision sensors enables a robust and versatile gesture-based control interface.
Transformer-based network with difference information aware attention module
Authors: Xu Jiahe , Liu Mengxin , Li Ziyan 
Published: December 2023

Abstract
Existing great progress has been made through remote sensing image change detection (CD) methods, which use convolutions and transformations appropriately. However, due to the complexity of the objects photographed on satellites, the out-of-phase of the same object may exhibit a fine feature diversity and a wide range of variations. Meanwhile, in the previous work, pure convolutional networks and Transformer networks that focus on local information perform better on non-local information. Therefore, current methods still have the problem of insufficient discrimination between irregular changes and diverse boundaries. Here, to solve this biphasic dilemma, we put forward a network that uses the difference information between bitemporal images as a guide to refine features. We use one feature map to subtract another and use multi-scale convolution to refine the difference map. We then designed an attention module similar to self-attention using differential information. In addition, considering the need for both local and global information in change detection, we use the full Swin Transformer framework with shift window self-attention to pass information between local areas. In addition, in order to enhance the network’s ability to recognize, members of our team reformulate supervised, traditional saliency map prediction through saliency and edge prediction. Notably, our proposed model significantly outperforms existing single-branch methods and state-of-the-art performance was achieved on four famous public datasets in terms of the F1-score index, interest in joint indices, and population indices.
Automating bird species classification: A deep learning approach with CNNs
Authors: Cai Renjun 
Published: December 2023

Abstract
Bird species identification and classification are challenging yet crucial for research and conservation. Traditional methods are labor-intensive, require specialized expertise, and can be prone to error. Recent advances in deep learning offer an automated solution to this complex problem. This study evaluates a convolutional neural network (CNN) model for classifying images of 525 bird species. The model employs transfer learning using the EfficientNetB0 architecture and was trained on over 84,000 images. With data augmentation, the model achieved 87% validation accuracy and 86.7% test accuracy, demonstrating its ability to overcome limited data and generalize well. Difficulties in obtaining balanced, high-quality data for each species were addressed through transfer learning and augmentation.
The Nicolai-map approach to supersymmetry
Authors: Lechtenfeld Olaf 
Published: December 2023

Abstract
In 1980 Hermann Nicolai proposed a characterization of supersymmetric theories that became known as the Nicolai map. This is a particular nonlocal and nonlinear field transformation, whose perturbative expansion is given by fermion-line trees with bosonic leaves. Quantum correlation functions can by evaluated using the inversely transformed fields in the free theory. After initial promise and excitement (fuelling the author’s PhD work!), the subject all but fell dormant for 35 years. Recently however, technical progress in the construction as well as a deeper insight into the nature of the map have been achieved, from quantum mechanics to super Yang–Mills in various dimensions. I will present the Nicolai map from this modern perspective and touch on some of the current developments.
Stable solitary vortices in two-dimensional quasi-integrable systems
Authors: Nakamula Atsushi , Obuse Kiori , Sawado Nobuyuki , Shimasaki Kohei , Toda Kouichi 
Published: December 2023

Abstract
Some solitary vortices to 2+1 quasi-integrable systems are discussed in the context of the planetary atmosphere. The Williams-Yamagata-Flierl (WYF) equation is one of the best candidates for the great red spot. We calculate the long-term simulation of the equation and find that the stable vortex is supported by a background zonal flow of a certain strength. The Zakharov-Kuznetsov (ZK) equation is a mimic of the WYF equation and considerably owes a great deal of its stability to the vortex. To learn more about the origin of longevity, we investigate the Painlevé test of the static ZK equation.
The Bethe Ansatz as a Quantum Circuit
Authors: Ruiz Roberto , Sopena Alejandro , Gordon Max Hunter , Sierra Germán , López Esperanza 
Published: December 2023

AbstractThe Bethe ansatz is an analytical method to solve exactly solvable models in quantum mechanics. It has been shown that the states of the Bethe ansatz can be prepared by a deterministic quantum circuit whose quantum gates were determined numerically. We report our progress in recasting the Bethe ansatz as a deterministic quantum circuit. We present the analytical expressions of the quantum gates. Formulae rely upon diagrammatic rules that define the wave functions of the Bethe ansatz by matrix product states. Based on the analytical expressions, we prove the unitarity of the quantum gates. We use our results to clarify on the equivalence between the coordinate and algebraic Bethe ansatze in light of matrix-product states.
Landau-Khalatnikov-Fradkin Gauge Transformations for the Propagator and Vertex in QED and QED2
Authors: Nicasio José , Bashir Adnan , Jentschura Ulrich D. , Edwards James P. 
Published: December 2023

Abstract
The non-perturbative Landau-Khalatnikov-Fradkin (LKF) transformations describe how Green functions in quantum field theory transform under a change in the photon field’s linear covariant gauge parameter (denoted ξ). The transformations are framed most simply in coordinate space where they are multiplicative. They imply that information on gauge-dependent contributions from higher order diagrams in the perturbative series is contained in lower order contributions, which is useful in multi-loop calculations. We study the LKF transformations for the propagator and the vertex in both scalar and spinor QED, in some particular dimensions. A novelty of our work is to derive momentum-space integral representations of these transformations; our expressions are also applicable to the longitudinal and transverse parts of the vertex. Applying these transformations to the tree-level Green functions, we show that the one-loop terms obtained from the LKF transformation agree with the gauge dependent parts obtained from perturbation theory. Our results will be presented in more comprehensive form elsewhere.
Supersymmetric Quantum Mechanics Formalism in a Modeling for Protein Folding
Authors: Drigo Filho E , Chahine J , Araujo M T , Ricotta R M 
Published: December 2023

Abstract
Recently, a mathematical method was developed to analyze the kinetics of the protein folding process, considering it as a diffusion process described by the Fokker-Planck equation and its solution, the time-dependent probability density. This work presents the main points of the methodology, based on the application of the algebraic formalism of Supersymmetric Quantum Mechanics associated with the variational method, to analyze the symmetric tri-stable free energy potential function that describes the unfolded and folded states, as well as an intermediate state of the protein.
Q-capacitor formulation of the ℂPN
nonlinear sigma model
Authors: Klimas P. , Kubaski L.C. , Sawado N. , Yanai S. 
Published: December 2023

Abstract
A multi-component ℂPN
model’s scalar electrodynamics is investigated. The model contains Q-balls/shells, which are non-topological compact solitons with time dependency eiωt
. Because of the compacton nature of solutions, Q-shells with another compact Q-ball or Q-shell inside their cavity can exist. Even if compactons do not overlap, they can interact with one another via the electromagnetic field. They look similar to the capacitor in the standard electromagnetism. We focus on the structure of such Q-capacitor with opposite charges.
Complex KdV rogue waves from gauge-Miura transformation
Authors: Adans Ysla F. , França Guilherme , Gomes José F. , Lobo Gabriel V. , Zimerman Abraham H. 
Published: December 2023

Abstract
The gauge-Miura correspondence establishes a map between the entire KdV and mKdV hierarchies, including positive and also negative flows, from which new relations besides the standard Miura transformation arise. We use this correspondence to classify solutions of the KdV hierarchy in terms of elementary tau functions of the mKdV hierarchy under both zero and nonzero vacua. We illustrate how interesting nonlinear phenomena can be described analytically from this construction, such as “rogue waves” of a complex KdV system that corresponds to a limit of a vector nonlinear Schrödinger equation.

Noncommutative spacetimes versus noncommutative spaces of geodesics
Authors: Herranz Francisco J , Ballesteros Angel , Gubitosi Giulia , Gutierrez-Sagredo Ivan 
Published: December 2023

Abstract
The aim of this contribution is twofold. First, we show that when two (or more) different quantum groups share the same noncommutative spacetime, such an ‘ambiguity’ can be resolved by considering together their corresponding noncommutative spaces of geodesics. In any case, the latter play a mathematical/physical role by themselves and, in some cases, they can be interpreted as deformed phase spaces. Second, we explicitly show that noncommutative spacetimes can be reproduced from ‘extended’ noncommutative spaces of geodesics which are those enlarged by the time translation generator. These general ideas are described in detail for the κ-Poincaré and κ-Galilei algebras.

Published: December 2023

Abstract
This is a brief survey of some recent results on infinitesimal symmetries of bundle gerbes and their relation to three Lie 2-algebras associated to manifolds equipped with a closed 3-form, such as 2-plectic manifolds: the Poisson Lie 2-algebra of local observables, the Lie 2-algebra of sections of an associated exact Courant algebroid, and the Atiyah Lie 2-algebra.
Exact solution for anisotropic Dirac materials interacting with position-dependent electric and magnetic fields
Authors: Mojica-Zárate J A , O-Campa D , Díaz-Bautista E 
Published: December 2023

Abstract
The interaction between massless Dirac fermions in anisotropic Dirac materials and position-dependent electric and magnetic fields is discussed here. The effect of the electric field strength in the energy spectrum and probability density of the eigenstates of the system is analyzed. Results show that the Landau levels are dispersive and the external electric field induces a collapse on them.
Integrable vortices on compact Riemann surfaces of genus one
Authors: Miyamoto K , Nakamula A 
Published: December 2023

Abstract
The Jackiw-Pi equation, which is one of the integrable vortex equations, is studied on a torus, a compact Riemann surface of genus one. The solutions are given in terms of doubly periodic functions, i.e., the elliptic functions. We reconsider the Jackiw-Pi vortex on a torus and provide the analytical method for determining the vortex number with explicit examples.
Liouville integrable binomial Hamiltonian system
Authors: Mullahasanoglu Mustafa 
Published: December 2023

Abstract
In this study, we work on a novel Hamiltonian system which is Liouville integrable. In the integrable Hamiltonian model, conserved currents can be represented as Binomial polynomials in which each order corresponds to the integral of motion of the system. From a mathematical point of view, the equations of motion can be written as integrable second-order nonlinear partial differential equations in 1 + 1 dimensions.
On polynomial symmetry algebras underlying superintegrable systems in Darboux spaces
Authors: Marquette Ian , Zhang Junze , Zhang Yao-Zhong 
Published: December 2023

Abstract
We review three different approaches to polynomial symmetry algebras underlying superintegrable systems in Darboux spaces. The first method consists of using deformed oscillator algebra to obtain finite-dimensional representations of quadratic algebras. This allow one to gain information on the spectrum of the superintegrable systems. The second method has similarities with the induced module construction approach in the context of Lie algebras and can be used to construct infinite dimensional representations of the symmetry algebras. Explicit construction of these representations is a non-trivial task due to the non-linearity of the polynomial algebras. This method allows the construction of states of the superintegrable systems beyond the reach of separation of variables. As a result, we are able to construct a large number of states in terms of Airy, Bessel and Whittaker functions which would be difficult to obtain in other ways. We also discuss the third approach which is based on the notion of commutants of subalgebras in the enveloping algebra of a Poisson algebra or a Lie algebra. This allows us to discover new superintegrable models in the Darboux spaces and to construct their integrals and symmetry algebras via polynomials in the enveloping algebras.
Quantum motion algebra
Authors: Pȩdrak A. , Góźdź A. 
Published: December 2023

Abstract
A notion of Quantum Motion Algebra (QMA) allows to construct quantum state spaces for various physical systems moving under a given group of motion. The main idea of QMA is a construction of a group algebra with involution generated by a group of motion G. After defining a linear and nonnegative functional on this algebra one can construct the appropriate quantum state space by means of the Gelfand-Naimark-Segal theorem. The QMA method can be also applied in the modeling of physical systems requiring additional degrees of freedom or additional constraints.
The presented paper gives a brief description of the QMA method. As an example of the QMA application, we present a model of nuclear collective pairing where the nonnegative functional is generated by a temperature dependent quantum density operator.
Dirac materials in parallel electromagnetic fields generated by supersymmetry
Authors: García-Muñoz Juan D , Pérez-Pedraza Julio Cesar , Raya A 
Published: December 2023

Abstract
In a Supersymetric Quantum Mechanics framework, the Dirac equation describing a Dirac material in the presence of electromagnetic fields is solved. Considering parallel static non-uniform electromagnetic fields, the Dirac equation is transformed into a two-dimensional system of equations. By means of variable separation, we can define one-dimensional eigenfunctions, which are solutions for two pairs of supersymmetric partner Schrödinger-like Hamiltonians. For Pöschl-Teller-like quantum potentials, we look for conditions that guarantee the existence of bound states, and determine an analytic zero-mode solution for the Dirac equation.
The Landau Problem and non-Classicality in Symplectic Carroll Symmetry
Authors: Petronilo G. X. A. , Ulhoa S.C. , Santana A. E. 
Published: December 2023

Abstract
Carroll’s group is shown as a group of transformations in a 5-dimensional space (𝒞) obtained from the embedding of the Euclidean space into a (4,1)-de Sitter space. Three of the five dimensions of 𝒞 are related to ℛ
3, and the other two to mass and time. A covariant formulation of Caroll’s group is established in phase space. The Landau problem was studied. Finally, the negative parameter of the Wigner function is calculated.
Variational Approach to Relativistic Fluid and Quantum Mechanics
Authors: Yahalom Asher 
Published: December 2023

Abstract
In previous papers we have shown how Schrödinger’s equation which includes an electromagnetic field interaction can be deduced from a fluid dynamical Lagrangian of a charged potential flow that interacts with an electromagnetic field. The quantum behaviour was derived from Fisher information terms which were added to the classical Lagrangian. It was thus shown that a quantum mechanical system is drived by information and not only electromagnetic fields.
This program was applied also to Pauli’s equations by removing the restriction of potential flow and using the Clebsch formalism. Although the analysis was quite successful there were still terms that did not admit interpretation, some of them can be easily traced to the relativistic Dirac theory. Here we repeat the analysis for a relativistic flow, pointing to a new approach for deriving relativistic quantum mechanics.
Classical conformal blocks, Coulomb gas integrals, and quantum integrable models
Authors: Pi¸atek Marcin R. 
Published: December 2023

Abstract
In this paper, we recall Richardson’s solution of the reduced BCS model, its relationship with the Gaudin model, and the known implementation of these models in conformal field theory. The CFT techniques applied here are based on the use of the free field realization, or more precisely, on the calculation of saddle-point values of Coulomb gas integrals representing certain (perturbed) WZW conformal blocks. We identify the saddle-point limit as the classical limit of conformal blocks. We show that this observation implies a new method for calculating classical conformal blocks and can be further used in the study of quantum integrable models.

The two integrals are of orders two and four, they are made from two components of the angular momentum and from the modified Laplace-Runge-Lenz vector, respectively.
