Help me with the Landau-Khalatnikov theory.

[DarkForXe]

I need to learn about this theory for my Final Year Project and I searched about it using google but all i found are about the theory being applied and nothing about the theory itself. Can anyone help me in this? Any lecture notes, books title, websites, pdf files will help me a lot or just teach me here! I need the theory for my study of two dimension ferroelectric material. Thanks alot, guys.

I know this is a good site for searching in old papers:

http://publish.aps.org/

Also use this for searcing after "Landau-Khalatnikov theory"

Have you not asked your supervisor? They should be able to put you in the right direction. othervise just spend lot of time in your library =P

Good luck with your project!

Sure, I would be happy to help you with the Landau-Khalatnikov theory. This theory is a mathematical model that describes the behavior of ferroelectric materials, such as two-dimensional ferroelectric materials, at low temperatures. It was developed by Soviet physicists Lev Landau and Isaak Khalatnikov in the 1950s.

To understand the Landau-Khalatnikov theory, it is important to have a basic understanding of ferroelectricity. Ferroelectric materials are materials that exhibit a spontaneous electric polarization, meaning that they have a permanent electric dipole moment. This polarization can be switched by applying an external electric field, making ferroelectric materials useful for various applications such as memory devices.

The Landau-Khalatnikov theory provides a framework for understanding the behavior of ferroelectric materials at low temperatures, where quantum mechanical effects become important. It takes into account the interactions between the electric polarization and the crystal lattice vibrations, known as phonons.

There are several resources available to learn more about the Landau-Khalatnikov theory. Some recommended sources include the original paper by Landau and Khalatnikov, titled "On the Theory of Ferroelectrics" (available online), the book "Theory of Elasticity" by Landau and Lifshitz, and the book "Ferroelectricity" by J.F. Scott. You can also find lecture notes and other resources on websites such as arXiv.org and ResearchGate.

I hope this information helps you in your study of the Landau-Khalatnikov theory. Good luck with your Final Year Project!
