2020 •

Ebubechukwu Okeke

This is a pre-publication version of a forthcoming book on quantum atom optics. It is written as a senior undergraduate to junior graduate level textbook, assuming knowledge of basic quantum mechanics, and covers the basic principles of neutral atom matter wave systems with an emphasis on quantum technology applications. The topics covered include: introduction to second quantization of many-body systems, Bose-Einstein condensation, the order parameter and Gross-Pitaevskii equation, spin dynamics of atoms, spinor Bose-Einstein condensates, atom diffraction, atomic interferometry beyond the standard limit, quantum simulation, squeezing and entanglement with atomic ensembles, quantum information with atomic ensembles. This book would suit students who wish to obtain the necessary skills for working with neutral atom many-body atomic systems, or could be used as a text for an undergraduate or graduate level course (exercises are included throughout). This is a near-final draft of the b...

On quantum Hall effect, Kosterlitz-Thouless phase transition, Dirac magnetic monopole, and Bohr-Sommerfeld quantization

2020 •

Allan Roy Elnar

We addressed quantization phenomena in transport and vortex/precession-motion of low-dimensional systems, stationary quantization of confined motion in phase space due to oscillatory dynamics or compacti fication of space and time for steady-state systems (e.g., particle in a box or torus, Brillouin zone, and Matsubara time zone or Matsubara quantized frequencies), and the quantization of sources. We discuss how the self-consistent Bohr-Sommerfeld quantization condition permeates the relationships between the quantization of integer Hall effect, fractional quantum Hall effect, the Berezenskii-Kosterlitz-Thouless vortex quantization, the Dirac magnetic monopole, the Haldane phase, contact resistance in closed mesoscopic circuits of quantum physics, and in the monodromy (holonomy) of completely integrable Hamiltonian systems of quantum geometry. In quantum transport of open systems, quantization occurs in fundamental units of quantum conductance, other closed systems in quantum units ...

Advances in Physics Theories and Applications

A General Theory of Micro and Macro Mechanics in Complex Vector Space: Applications to Quantum Theory and Gravitation

2024 •

Muralidhar Kundeti

A new pre-quantum level physical theory underlying the quantum mechanics has been developed and its epistemological features are mainly derived from the fluctuating classical electromagnetic zeropoint field which induces random oscillations on charged particle. In complex vector space, the average random oscillations of the charged particle are treated as complex rotations so that a particle has extended structure. It is found that the quantum nature of particles arises from the superposition of internal oscillations on the center of mass motion. Using Lagrangian mechanics in complex vector space, a generalized Newton's equation is derived and which is shown to be acceptable for both micro and macro mechanics. The generalized Newton's equation contains additional relativistic terms at the micro level. Further, a complex Hamilton-Jacobi equation is derived and which is used to solve quantum mechanical problems in classical approach. The presence of zeropoint field also produces modifications in the central potential and the additional terms are responsible for the effects like advance of planets perihelion and deflection of light near massive objects at macro level. Further, in the case of atoms such terms lead to the estimation of Lamb shift using stochastic electrodynamics. The consideration of extended particle structure in stochastic electrodynamics allows deriving mass correction and charge correction and consequently the estimation of anomalous magnetic moment. The fundamental deeper level theory developed here, may further enhance the efforts for research connecting micro and macro aspects of matter.

FAQs

Is quantum mechanics physics hard? ›

Quantum mechanics is deemed the hardest part of physics. Systems with quantum behavior don't follow the rules that we are used to, they are hard to see and hard to “feel”, can have controversial features, exist in several different states at the same time - and even change depending on whether they are observed or not.

Why did Einstein disagree with quantum mechanics? ›

He thought it was incomplete. It was saying the wrong things about the true nature of reality. So what was quantum theory saying? The theory states that there is an absolute limit to what we can know about what goes on in nature at the atomic level.

Why is quantum physics so hard on Reddit? ›

Quantum mechanics, like all scientific theories, are about describing how the universe (or some aspect of it) works. Quantum mechanics is complex because as best we can tell, it's describing aspects of the universe that are complex.

What is the hardest part of quantum mechanics? ›

The probabilistic nature of quantum mechanics thus stems from the act of measurement. This is one of the most difficult aspects of quantum systems to understand.

Is quantum physics harder than mathematics? ›

But a more fair comparison is between Quantum Field Theory (the relativistic version of quantum mechanics) and General Relativity, and the answer is that Quantum Field Theory is harder and more complicated for several reasons.

Can I learn quantum physics by myself? ›

Quantum Physics does not come easy to most people as it is not at all intuitive, but I encourage you to keep trying and you will get it eventually. I will end with this: "If you think you understand quantum mechanics, you don't understand quantum mechanics."

What famous scientist didn t like quantum mechanics? ›

Given all these affronts to both common sense and classical physics, you would be forgiven if you figured there must be something wrong with quantum physics. Albert Einstein certainly did.

What is the biggest problem in quantum mechanics? ›

Problem of time: In quantum mechanics, time is a classical background parameter, and the flow of time is universal and absolute. In general relativity, time is one component of four-dimensional spacetime, and the flow of time changes depending on the curvature of spacetime and the spacetime trajectory of the observer.

What was Einstein's IQ? ›

Most theorists peg Einstein's IQ score between 160-190. Because he never took any kind of test to measure his intelligence, the definite score is still a mystery. But without a doubt, he was a brilliant man with an incredible brain. Who Has the Highest IQ in the World Today?

Does anyone fully understand quantum physics? ›

Quantum information is mathematically inequivalent to classical information. The quote “nobody understands quantum mechanics” is attributed to Richard Feynman (1965), and Carroll opens his opinion piece with it.

Is quantum physics harder than astrophysics? ›

Is quantum Mechanics harder than astrophysics? Quantum physics and astrophysics are two of the most challenging and fascinating fields of science. Both fields require a deep understanding of physics and mathematics, but they also have their own unique challenges.

Can a normal person learn quantum mechanics? ›

Anyone can learn quantum mechanics, but only with the proper motivation. The extent of this knowledge then depends on the mathematical background.

Who is the father of quantum mechanics? ›

Niels Bohr and Max Planck, two of the founding fathers of Quantum Theory, each received a Nobel Prize in Physics for their work on quanta.

Is quantum mechanics more physics or chemistry? ›

Quantum mechanics is the branch of physics that deals with the behavior of matter and light on a subatomic and atomic level. It attempts to explain the properties of atoms and molecules and their fundamental particles like protons, neutrons, electrons, gluons, and quarks.

How hard is it to be a quantum physicist? ›

A strong foundation of maths.

Therefore, the short answer to whether or not studying quantum physics is complex or not is yes. Of all scientific disciplines that deal with physics, quantum physics has been deemed most difficult by experts.

What is most difficult in physics? ›

That said, one of the most difficult in physics is the concept of quantum-mechanical spin. It is very counter-intuitive and requires rather advanced math, such as group representation theory and vector bundles, to formulate and understand properly.

Is quantum physics harder than rocket science? ›

Is Quantum Physics harder than Rocket Science? - Quora. Both are equally challenging, and both require you to have a capable brain and education to do them properly. It depends on the person, too, a field of science can be difficult for one but seemingly like a second nature for the other.
