Quantum Field Theory: Underdetermination, Inconsistency, and Idealization [PDF]
, 2009 Quantum field theory (QFT) presents a genuine example of the underdetermination of theory by empirical evidence. There are variants of QFT which are empirically indistinguishable yet support different interpretations.

Octonionic Magical Supergravity, Niemeier Lattices, and Exceptional & Hilbert Modular Forms
Fortschritte der Physik, Volume 72, Issue 2, February 2024.Abstract The quantum degeneracies of Bogomolny‐Prasad‐Sommerfield (BPS) black holes of octonionic magical supergravity in five dimensions are studied. Quantum degeneracy is defined purely number theoretically as the number of distinct states in charge space with a given set of invariant labels.

Multi-Well Potentials in Quantum Mechanics and Stochastic Processes
Symmetry, Integrability and Geometry: Methods and Applications, 2010 Using the formalism of extended N=4 supersymmetric quantum mechanics we consider the procedure of the construction of multi-well potentials. We demonstrate the form-invariance of Hamiltonians entering the supermultiplet, using the presented relation for ...

Superstructures on graded phase space [PDF]
, 1988 In this thesis we study problems associated with the generalisation, to include Grassmann type variables, of the 'group theoretical' approach to quantisation of C.Isham [37].

Fortschritte der Physik, Volume 72, Issue 2, February 2024.Abstract The string theory landscape may include a multitude of ultraviolet embeddings of the Standard Model, but identifying these has proven difficult due to the enormous number of available string compactifications. Genetic Algorithms (GAs) represent a powerful class of discrete optimisation techniques that can efficiently deal with the immensity of

Semiclassical monopole calculations in supersymmetric gauge theories [PDF]
, 2000 We investigate semiclassical contributions to correlation functions in N = 1 supersymmetric gauge theories. Our principal example is the gluino condensate, which signals the breaking of chiral symmetry, and should be exactly calculable, according to a ...

Solvable quantum mechanical examples of broken supersymmetry
, 1993 We construct several analytically solvable examples of broken supersymmetry in non-relativistic quantum mechanics. Our examples are motivated from known shape-invariant potentials obeying unbroken supersymmetry and are obtained from them via suitable ...

Gauge Theory and Supergravity Duality in the PP-Wave Background [PDF]
, 2005 We test the matrix theory conjecture in the pp-wave by studying two-body interactions between gravitons and membranes. We compute the one-loop effective potential of matrix theory and compare it to the light cone Lagrangian of linearized supergravity. We

A Method of Constructing Superpotentials by Combining Two Functions Based on Shape Invariance
Advances in Mathematical Physics, Volume 2024, Issue 1, 2024.Supersymmetric quantum mechanics (SUSYQM) plays an important role in solving the Schrödinger equation, and it is also important to find more superpotentials that can be solved accurately. On the basis of studying the characteristics of existing superpotentials, the authors find a missing superpotential and put forward a method by combining two ...

THEORETICAL FRAMEWORKS FOR UNIFIED FIELD THEORY: PROGRESS AND CHALLENGES
Worldwide Journal of Physics, 2023 The quest for a Unified Field Theory (UFT) represents a cornerstone challenge in theoretical physics, aiming to integrate all fundamental interactions—gravitational, electromagnetic, weak, and strong forces—into a singular, coherent framework. This study
