I am interested in materials where surprising behavior emerges from a dynamic, and sometimes subtle, interplay between many degrees of freedom.  A fundamental understanding of these emergent properties is key to designing new devices and tailoring materials with beneficial properties for energy production, harvesting, and storage.  The complexity of these systems means that large-scale, numerical simulations are crucial to an understanding of the root causes of material properties and their expression in different experimental probes.  I work closely with experimental groups who utilize leading light sources, such as SSRL and LCLS here at Stanford, to image electron dynamics through photon spectroscopies and use simulations to better interpret the results and guide future research.

In our group we study materials with unconventional magnetic and/or electronic properties, with the aim of better understanding emergent behavior in strongly correlated systems. We employ a combination of thermodynamic, transport and scattering measurements, often in high magnetic fields, and use a variety of techniques to grow high quality single crystals of the materials that we study. Current interests include superconductivity, charge density wave formation, electronic nematic order, aspects of quantum magnetism and the behavior of electrons in low-dimensional materials.

The unsolved problems that show up in high-temperature superconductors are fascinating challenges. I look for clues by trying to reconcile the diverse properties of these superconductors, and try to resolve them by synthesis of film and crystals.

My research interests are mostly focused on the field of mesoscopic physics, which explores length scales between the microscopic size of individual atoms and the macroscopic scale of everyday objects. Over the last decade, mesoscopic physics has forced us to grapple with new ways of thinking about quantum mechanics, measurement, and dephasing, especially for systems of interacting particles.

In my lab, we approach the mesoscopic regime in semiconductor devices, where electrons can be confined to small “boxes” and thus are restricted to discrete quantized states (instead of being able to move freely) in one, two, or even all three spatial dimensions.

Our group’s general aim is to contribute to the understanding of current problems in Physics including gravitational physics, quantum physics and condensed matter physics of strongly correlated electron systems. We use novel experimental techniques that are mostly developed in our laboratory.

Member, National Academy of Sciences 2010

I am interested in the qualitative understanding of the macroscopic and collective properties of condensed matter systems, and on the relation between this and the microscopic physics at the single electron or single molecule scale.

I have been particularly interested in exploring the spectacular consequences of strong correlation effects in electronic materials and devices where the low energy properties are qualitatively different from those of a non interacting electron gas. This field of study has been made particularly rich and exciting by the seemingly non-ending sequence of unexpected experimental discoveries that have occurred in over the past couple of decades — discoveries which undermine accepted beliefs and raise conceptually deep questions concerning the emergent behavior of systems with many strongly interacting degrees of freedom.

The Lee group seeks to develop a deeper understanding of quantum materials through research activities involving neutron scattering, x-ray scattering, and crystal growth. We are particularly interested in novel many-body states such as quantum spin liquids, exotic superconductivity, and topological phases of matter.

My academic career at Stanford has been focused on research efforts to understand the electronic properties of semiconductor surfaces and interfaces on an atomic scale using synchrotron radiation of importance for the development of modern electronic devices. I have taken a great interest in the development of synchrotron radiation and free electron laser facilities and instrumentation, and research policies for large scale facilities. I have been (and still am) a member/chairperson of a large number of review and advisory committees.

I am interested in the ultrafast properties of materials, using atomic-scale real-time probes to visualize and control processes of relevance to energy conversion and information processing.

What new science and technologies lurk at the smallest scales of condensed matter?  How does physics change in lower dimensions?  My experimental research group combines condensed matter physics, nanoscale science and technology, and atom manipulation to address these and related questions.  We focus on ultra-high resolution quantum imaging and probes of interesting electronic systems.  We also specialize in the science of atomic and molecular manipulation for atom-by-atom assembly of exotic nanostructures and artificial materials.

The main focus of my research lies in understanding the behavior of materials under compression. High pressure science is exceedingly multidisciplinary. Pressure induces dramatic changes in materials, adding a new dimension to applications in Earth, planetary, environmental, energy-related, biological, electromagnetic, optical, superhard and nano- materials, and contributing to our fundamental understanding of condensed-matter physics and chemistry. Pressure is also a clean, continuous, tuning knob for fundamental scientific research: testing theories, discovering new phenomena and novel materials.

Electrons create magnetic fields, so materials that manifest quantum mechanical and strongly correlated electron behavior must have magnetic signatures. Although distinctive, interesting, and informative, these signatures are hard to measure. Twelve years ago, I set out to build a group based on the strategy of specialized magnetic nanoprobes for basic condensed matter studies. This strategy enables the advances in knowledge described in the publications section of my group’s web site, as well as in my ongoing work and the ongoing work of my group alumni in their current positions.

Joseph W. Orenstein earned his Ph.D. in Solid State Physics from the Massachusetts Institute of Technology in 1980. He received an IBM Postdoctoral Fellowship 1978-79, and was a Member of the Technical Staff at the AT&T Bell Laboratories from 1981 to 1989. In 1989, he was made a Distinguished Member of the Technical Staff. He joined the Physics Dept. at UC Berkeley in 1990. He is a Fellow of the American Physical Society.

I am primarily interested in theoretical condensed matter physics and especially theories of excited state electronic structure and x-ray and electron spectra, e.g. as probed at modern synchrotron x-ray facilities. We are particularly interested in real-space, real-time approaches to many-body physics.

I am an experimentalist who studies dynamics that occur on extremely short time and distance scales. My background is in the areas of ultrafast laser, high field, accelerator, x-ray and condensed matter physics.

My main research interest lies in the area of condensed matter and materials physics. The questions that motivate my research are: what is the nature of quantum matter? How does complexity give rise to unusual and extreme properties?

His research interests include:

• developing numerical algorithms and fast implementation to accelerate scientific simulations
• developing efficient and robust algorithms and implementations for solving inverse problems
