A unifying theme in understanding the macroscopic properties of quantum materials is the concept of emergence, where novel effects and unusual phases arise from the interplay of spin-orbit effects, band topology and strong correlation.
In the thin cylinder regime Haldane’s pseudo-potential corresponding to one-third filling results in a frustration-free fermionic lattice Hamiltonian which is dipole-conserving with an added electrostatic interaction. Its zero-energy eigenspace is exponentially large.
"Spectral Gaps, Incompressibility and Fragmented Matrix-Product State in a Fractional Quantum Hall System"

Unfortunately, due to the rapidly escalating health concerns relating to the spread of the coronavirus disease (COVID-19) and in an abundance of caution, we have decided to postpone the workshop until October...
As the age of WIMP-scale dark matter (DM) draws to a close thanks to the ever-increasing sensitivity of direct detection experiments, the majority of sub-GeV DM parameter space remains to be explored. Sub-GeV DM can excite electronic transitions in a variety of molecular and nano-scale systems which have sub-eV scale thresholds.
We propose a novel explanation for the smallness of the observed cosmological constant (CC). Regions of space with a large CC are short lived and are dynamically driven to crunch soon after the end of inflation. Conversely, regions with a small CC are metastable and long lived and are the only ones to survive until late times.
