Observation of a Dissipation-Induced Classical to Quantum Transition

J. Raftery, D. Sadri, S. Schmidt, H. E. Tureci, A. A. Houck
In this work, we study a novel dynamical phase transition of light, where photon-photon interactions and dissipation into the environment are key aspects of the physics. Together they give rise to a transition from a region of classical behavior into a regime where quantum effects dominate. The transition was observed in a Jaynes-Cummings dimer built from two coupled microwave cavities (shown in the upper picture. In this system, photons repel each other due to the presence of nearby superconducting

Landau Quantization and Quasiparticle Interference in the 3D Dirac Semimetal Cd3As2

Robert J. Cava and Ali Yazdani
Condensed matter systems provide a rich setting to realize Dirac and Majorana fermionic excitations and the possibility to manipulate them in materials for potential applications. Recently, it has been proposed that Weyl fermions, which are chiral, massless particles, can emerge in certain bulk materials or in topological insulator multilayers and can produce unusual transport properties, such as charge pumping driven by a chiral anomaly. A pair of Weyl fermions protected by crystalline symmetry, effectively forming a massless

Enzyme Molecules as Nanomotors

Samudra Sengupta, Krishna K. Dey, H. S. Muddana, Tristan Tabouillot, Michael E. Ibele, Peter J. Butler, and Ayusman Sen (Penn State)
MRSEC researchers have recently discovered that enzymes - molecules that catalyze chemical reactions in cells - move during the reaction.  Although this property is well known for motor proteins, it has not been previously known that movement is a general consequence of enzymatic reactions.  This movement depends on the concentration of the enzyme's substrate (the fuel for its reaction) and causes individual enzyme molecules t

Engineering Cellular Response Using Nanopatterned Bulk Metallic Glass (BMG)

Biomaterials implanted in the body evoke a “Foreign body response” which results in encapsulation of the material in a collagen-rich protein capsule. Fibroblast cells, which produce collagen, mediate this process that leads to biomaterial rejection / device failure in vivo. Surface nanotopography of BMGs can be used to engineer fibroblast-material interactions.
