Superconductivity = zero resistance 
New research digs into Cooper pair density and how it drives the superconducting state.
Big implications for quantum tech + energy.

(so I've been hunting for an information carrier…)
…a family of exactly solvable #quantumspin models in one and two dimensions, in which free #paraparticles emerge as quasiparticle excitations, and their exchange statistics can be physically observed and are notably distinct from fermions and bosons…the possibility of a new type of #quasiparticle in #condensedmatter systems and—more speculatively—the potential for previously unconsidered types of #elementaryparticle.
Yesterday Charlie-Ray Mann gave a talk as a part of the "Many-Body Quantum Optics" program at KITP. Charlie is a postdoc working in the same group as me. Part of presented work (2D numerics which is not directly referenced) was done by me within the QUINTO project. You can listen to the recording of the talk here: https://online.kitp.ucsb.edu/online/mbqoptics24/mann/

Spin liquid
As an example of how a topological order can look like, one can look at simplified picture of so-called Z2 spin liquid. This type of topological order is postulated to occur in some “frustrated magnets”.

Hi!
We are conducting a research project on the intersection of quantum optics and condensed matter. We study what happens if an ordered array of atoms absorbs many photons, thus becoming a complex system of many interacting particles. We want to find and exploit analogies between such systems and so-called topological orders, and build a “bridge” between the two fields of physics.

Hello! I'm a #TheoreticalPhysicist working in #Quantum #CondensedMatter #Physics, currently a #MarieSklodowskaCurie Fellow at FU Berlin. I'm interested in how #disorder affects quantum systems, and how we can use it to stabilise exotic phases of matter.
