The physics of quantum materials

Most proponents of dialectical materialism claim it to be the most coherent understanding of developments within sciences.Hence, it should concern them that there exist seemingly contradictory dialectical materialist understandings of the accepted theory of micro physics.Among physicists who accept dialectical materialism, there are ones who argue in favour of the standard interpretation of quantum physics, as well as others who oppose it.We discuss arguments of two such physicists, Valdimir Fock and David Bohm.They both give physical arguments against the neo-Kantian and positivist elements of the dominant Copenhagen interpretation of quantum mechanics.While Bohm uses the notion of 'qualitative infinity of nature' against the maximalist form of this interpretation, Fock defends a minimalist form of this interpretation with the argument of the 'relativity to the means of observation'.Similarly, their proposals differ on the key question of the origin of randomness in quantum measurements.Despite having a consistent formalism, there are gaps in the physical understanding of quantum physics, and at least part of their divergent interpretations relates to these gaps.It is argued that the divergent views of Bohm and Fock should not be read polemically.Rather, they together help develop a more comprehensive characterization of dialectical materialism as a worldview in development.Arguments of Bohm and Fock explore and substantiate materialist and dialectical themes in physics.Their divergence shows that dialectical materialism cannot pre-empt science.In fact, as sciences discover new properties of matter, dialectical materialism needs to continually renew its repertory of generalized concepts to grasp these properties.

Abstract Quantum materials exhibit a wide array of exotic phenomena and practically useful properties. A better understanding of these materials can provide deeper insights into fundamental physics in the quantum realm as well as advance information processing technology and sustainability. The emergence of digital quantum computers (DQCs), which can efficiently perform quantum simulations that are otherwise intractable on classical computers, provides a promising path forward for testing and analyzing the remarkable, and often counter-intuitive, behavior of quantum materials. Equipped with these new tools, scientists from diverse domains are racing towards achieving physical quantum advantage (i.e. using a quantum computer to learn new physics with a computation that cannot feasibly be run on any classical computer). The aim of this review, therefore, is to provide a summary of progress made towards this goal that is accessible to scientists across the physical sciences. We will first review the available technology and algorithms, and detail the myriad ways to represent materials on quantum computers. Next, we will showcase the simulations that have been successfully performed on currently available DQCs, emphasizing the variety of properties, both static and dynamic, that can be studied with this nascent technology. Finally, we work through three examples of how to perform various materials simulation problems on DQCs, with full code included in the supplementary material ( https://stacks.iop.org/QST/6/043002/mmedia ). It is our hope that this review can serve as an organized overview of progress in the field for domain experts and an accessible introduction to scientists in related fields interested in beginning to perform their own simulations of quantum materials on DQCs.

Quantum Resonance Synchronization (QRS) represents a paradigm shift in materials science, offering the potential to manipulate physical properties through precisely orchestrated quantum phenomena. This paper explores the application of QRS to enhance material characteristics, focusing on the generation and stabilization of resonant states within materials leveraging quantum entanglement for feedback control. We detail a novel methodology for inducing and maintaining these resonant states, demonstrating the ability to influence macroscopic material behavior with unprecedented precision. The research highlights the potential for revolutionizing materials design and engineering, offering a pathway toward materials with tailored properties and enhanced functionalities. The core mechanism centers around creating and maintaining quantum entanglement within a material's structure, thereby facilitating controlled shifts in physical characteristics. This work presents a foundational study exploring the principles and potential applications of QRS, anticipating advancements in materials science and technology.
