Advanced Condensed Matter Physics: Quantum Phase Transitions, SPT Phases, Spin Liquids, Majorana Fer

This final volume takes you to physics' frontier - where particles with no charge exist, spins never freeze, and black holes help understand superconductors. Welcome to the wild side of quantum matter.

✨ **What's Inside?**
✔ **Quantum critical points** - Phase transitions at absolute zero
✔ **SPT phases** - Symmetry-protected topological order
✔ **Kitaev honeycomb model** - Exactly solvable spin liquids
✔ **Majorana fermions** - Particles that are their own antiparticles
✔ **AdS/CMT correspondence** - When black holes explain metals

**Why This Book?**
Because this is where textbook physics ends and discovery begins. These ideas are rewriting what we know about matter itself.
