Gregory C. Levine

Professor of Physics and Astronomy


PHD, 1989, Columbia University; MA, 1985, Columbia University; BA, 1983, Columbia University


Gregory Levine received his PhD in Physics from Columbia University in 1989 and was a postdoctoral fellow at the Texas Center for Superconductivity before joining the Physics Department at Hofstra in 1993. In 2004-6, Professor Levine was a KITP Scholar at the Kavli Institute for Theoretical Physics at the University of California. He has twice received research grants from the Research Corporation/Cottrell Foundation. Professor Levine has worked in the fields of nonlinear dynamics, strongly correlated systems (such as superconductivity and low dimensional magnetism), dissipative quantum systems and quantum information.

Research Interests

Quantum Information
The concept of information represented in a purely quantum mechanical form was first developed in an effort to generalize ordinary computation—operations performed on numbers represented as bits (0 and 1). In the quantum version of computation, the elements are quantum bits (qubits) that may be in an uncertain state, termed a quantum ”superposition” between states 0 and 1. Quantum computation has been shown to offer dramatic speed improvement over classical computation for certain classes of problems.  An essential ingredient of quantum computation is a type of long range-correlation between qubits termed “entanglement”—the feature of quantum mechanics Einstein famously called “…spooky action at a distance.”  My research has recently focused on the question of how entanglement dynamically evolves in a system with many quantum particles. I have also begun a project exploring the use of the newly discovered correspondences (dualities) between gravitational physics and quantum field theory to study entanglement entropy. Although these dualities were developed in string theory in a high energy physics context, they present a promising approach to a certain class of problems in condensed matter physics.

Dissipative Quantum Systems
Another area of my research focuses on the quantum mechanics of “open systems”—the quantum mechanics of systems embedded in a large and stochastic environment. This subfield of physics attempts to address how classical physics, which governs macroscopic or large-scale physics behavior, emerges from quantum mechanics, which governs the microscopic or small-scale behavior. As a quantum system is made larger, its wave-like properties become more sensitive to the coherence destroying effects of the environment. In fact, it is decoherence that renders the universe demonstrably classical (and makes Newtonian mechanics, rather than quantum mechanics, valuable to an engineering student.) This topic is at the frontier of modern theoretical physics and has a direct impact upon a number of pure and applied fields of physics such as quantum computing, conductivity and superconductivity in strongly correlated materials, and quantum cosmology.
