My research focuses on a variety of phenomena associated with plasmas and liquid metals. Current research projects are: investigation of magnetic field self-generation by flows of conducting metal (experimental dynamo research); propagation of electron Bernstein waves in plasmas; stabilization of current driven instabilities in fusion plasmas by flowing liquid metal walls; transport of energy and … Continued
I study how cell adhesion and migration is regulated by the physical behaviors and structure of the actin cytoskeleton, focal adhesions and cell-cell adhesions and how the physical behaviors of complex cytoskeletal machines emerge from their molecular constituents. My research employs approaches from condensed matter physics, cell biology and biochemistry to study the physical properties … Continued
An interesting way to formulate some problems that arise in science and industry is the following: given sets A and B (usually in a high dimensional Euclidean space), find a point in their intersection. This presentation of the problem would be empty if it were not for the fact that in many situations, finding an … Continued
Motivated by current cosmological observations, as well by fundamental problems of the existing paradigm (of particle physics and gravity), such as the cosmological constant and the hierarchy problems, I intend to study theories that modify gravity at very large (cosmological) and short distances, but keep all the success of the standard theory at shorter length … Continued
My present research is focused on quantum phenomena in nanomagnets, time crystals, and cryogenic amplification for high speed time resolved measurements.
My research is focused on the macroscopic quantum physics of many-body quantum matter including studies of superconductors, superfluids, supersolids, heavy fermions, topological condensates, and of spin & monopole liquids.
My group is taking the techniques of precise quantum control and measurement that characterize modern atomic physics and applying them to the system of diatomic molecules. Molecules are more complex than atoms because of their internal vibrational and rotational motions, and this makes them more difficult to control. However, our group has learned how to … Continued
Ultracold atoms and molecules are incredibly versatile tools for creating designer science experiments. Their versatility stems from the many forms of precise control that physicists have developed over recent years, including: the use of laser cooling to remove nearly all entropy, the creation of almost arbitrary potential energy landscapes with optical fields, the ability to … Continued
I work in the field of theoretical condensed matter physics, focusing on the electronic properties of advanced materials of fundamental and technological interest. In the past few decades, our group has established itself as one of the leading groups in first-principles electronic-structure calculations. Our earlier studies on simple metal clusters have become a classic work … Continued
We want to understand how animal cells sense, generate, and respond to forces in their environment. Our goal is to generate a detailed physical model for cell viscoelasticity and to relate it to the cells’ biochemical regulatory pathways. Such understanding will likely prove crucial for medical studies related to cancer metastasis, stem cell differentiation, and … Continued
