Fractional Quantum Hall states Under Decoherence
Zijian Wang - Tsinghua University
In this talk, I will introduce our recent studies on the effect of decoherence on fractional quantum Hall fluids and their robustness as topological quantum memories. Specifically, we examine the behavior of Laughlin states and Moore-Read states under dephasing noise using the plasma analogy as well… -
Nonabelian Anyon Condensation in 2+1d topological orders: A String-Net Model Realization
Yidun Wan - Fudan University
In this talk, we develop a comprehensive framework for realizing anyon condensation of topological orders within the string-net model by constructing a Hamiltonian that bridges the parent string-net model before and the child string-net model after anyon condensation. Our approach classifies all… -
The Charge Gap exceeds the Neutral Gap in Fractional Quantum Hall Systems
Bruno Nachtergaele - University of California, Davis
The so-called pseudo-potentials modeling fractional quantum Hall systems are quantum many-body Hamiltonians that are frustration free and have two symmetries, one related to the conservation of charge (particle number) and another to the conservation of dipole moment (angular momentum), in addition… -
Exploring Quantum Many-Body Scars: Anomalies to Thermalization in Quantum Systems
Julia Wildeboer - Brookhaven National Laboratory
Quantum many-body scars (QMBS) have emerged as a captivating anomaly within the landscape of quantum physics, challenging the conventional expectations of the eigenstate thermalization hypothesis (ETH). According to ETH, an isolated quantum system is expected to evolve toward thermal equilibrium… -
An SPT-LSM theorem for weak SPTs with non-invertible symmetry
Sal Pace
Like ordinary symmetries, non-invertible symmetries can characterize Symmetry-Protected Topological (SPT) phases. In this talk, we will discuss weak SPTs protected by projective non-invertible symmetries. Projective symmetries are ubiquitous in quantum spin models and can be leveraged to constrain… -
Microscopic Roadmap to a Yao-Lee Spin-Orbital Liquid
Hae-Young Kee - University of Toronto
The exactly solvable spin-1/2 Kitaev model on a honeycomb lattice has drawn significant interest, as it offers a pathway to realizing the long-sought after quantum spin liquid. Building upon the Kitaev model, Yao and Lee introduced another exactly solvable model on an unusual star lattice featuring… -
Exotic superconductivity in UTe2
Sheng Ran - Washington University in St. Louis
UTe₂ is an intriguing recently discovered superconductor that exhibits a wide range of exotic properties. Experimental evidence increasingly supports spin-triplet pairing, and under pressure or in magnetic fields, UTe₂ displays multiple superconducting phases, including a remarkable reentrant phase… -
Towards Anderson localisation of light by cold atoms
Robin Kaiser - The French National Centre for Scientific Research
The quest for Anderson localization of light is at the center of many experimental and theoretical activities. Cold atoms have emerged as interesting quantum system to study coherent transport properties of light. Initial experiments have established that dilute samples with large optical thickness… -
Condensation in topological orders and topological holography
Rui Wen - University of British Columbia
Condensation of topological defects is the foundation of the modern theory of bulk-boundary correspondence, also known as topological holography. In this talk, I discuss string condensation in 3+1D topological orders, which plays a role analogous to anyon condensation in 2+1D topological orders. I… -
A Practical Guide to the Patent Process for Scientists and Engineers
Scientists are always working on the forefront of technology, developing new ideas and solving important problems. But many researchers don’t realize that their work can be protected—and potentially monetized for a profit!—by filing a patent application. In this presentation, we will talk about the…
