Confined Atomic Systems

I investigate the intersection of quantum information theory and condensed matter physics, particularly entanglement properties of many-body systems and their applications to quantum computing.

Quantum Information

Quantum information theory provides powerful tools for understanding quantum many-body systems. My research explores the connections between quantum entanglement, quantum computation, and condensed matter physics.

Key research directions include:

  • Characterizing entanglement in quantum many-body systems
  • Developing entanglement-based probes of quantum phase transitions
  • Studying the relationship between entanglement and geometry in holographic systems
  • Investigating quantum error correction in topological systems
  • Exploring quantum algorithms for simulating condensed matter systems

My recent work has focused on understanding how entanglement entropy scales at quantum critical points with emergent gauge fields, providing new insights into the structure of quantum correlations in these systems.

Entanglement in Many-Body Systems

A major focus of my research is understanding the structure of entanglement in quantum many-body systems. This includes:

  • Developing new measures of entanglement for many-body systems
  • Studying the scaling of entanglement entropy in critical systems
  • Investigating the relationship between entanglement and quantum phase transitions
  • Exploring the connection between entanglement and computational complexity

Quantum Computing Applications

I am also interested in applications of quantum information theory to quantum computing, particularly:

  • Topological quantum computing using Majorana fermions
  • Quantum error correction using topological codes
  • Quantum algorithms for simulating strongly correlated systems
  • Quantum machine learning for condensed matter problems
