Emergent phenomena induced by spin-orbit coupling at surfaces and interfaces.

Area of Science:

• Condensed matter physics
• Materials science

Background:

• Spin-orbit coupling (SOC) is a relativistic electron interaction crucial for condensed matter phenomena.
• Low dimensionality combined with SOC has led to emergent phases like chiral spin textures and spin-polarized states.

Purpose of the Study:

• To discuss spin-orbit coupling as a method for generating new physical phenomena.
• To explore the potential of SOC-based thin films and heterostructures for room-temperature applications.

Main Methods:

• Theoretical discussion of spin-orbit coupling effects.
• Analysis of low-dimensional materials (thin films, heterostructures).

Main Results:

• Emergence of novel phases of matter due to interplay between SOC and low dimensionality.
• Identification of robust, room-temperature exploitable phenomena.
• Demonstration of spin-polarized surface and interface states.

Conclusions:

• Spin-orbit coupling is a key mechanism for discovering new physics in low-dimensional systems.
• SOC-based materials offer significant technological promise for future spin-based devices operating at room temperature.
