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… -
Computational Phase Transitions in Two-Dimensional Antiferromagnetic Melting
Zach Weinstein - University of California, Berkeley
A computational phase transition in a classical or quantum system is a non-analytic change in behavior of an order parameter which can only be observed with the assistance of a nontrivial classical computation. Such phase transitions, and the computational observables which detect them, play a… -
Non-Hermitian operators in many-body physics
Jacob Barnett - University of the Basque Country
Non-Hermitian Hamiltonians are a compulsory aspect of the linear dynamical systems that model many physical phenomena, such as those in electrical circuits, open quantum systems, and optics. Additionally, a representation of the quantum theory of closed systems with non-Hermitian observables… -
Replica topological order in quantum mixed states and quantum error correction
Roger Mong - University of Pittsburgh
Topological phases of matter offer a promising platform for quantum computation and quantum error correction. Nevertheless, unlike its counterpart in pure states, descriptions of topological order in mixed states remain relatively under-explored. We will give various definitions for replica… -
Quantum Spin Liquid Oasis in Desert States of Unfrustrated Spin Models: Mirage ?
Baskaran Ganapathy - Institute of Mathematical Sciences
Hilbert spaces are incomprehensibly vast and rich. Model Hamiltonians are space ships. They could take us to new worlds, such as cold \textit{spin liquid oasis} in hot regions in Hilbert space deserts. Exact decomposition of isotropic Heisenberg Hamiltonian on a Honeycomb lattice into a sum of 3 non… -
The Stability of Gapped Quantum Matter and Error-Correction with Adiabatic Noise - VIRTUAL
Ali Lavasani - University of California, Santa Barbara
The code space of a quantum error-correcting code can often be identified with the degenerate ground-space within a gapped phase of quantum matter. We argue that the stability of such a phase is directly related to a set of coherent error processes against which this quantum error-correcting code… -
The Ising Model on $S^2$ - The Affine Conjecture
Richard Brower - Boston University
A formulation of the 2-dimensional Ising model on a triangulated Riemann sphere is proposed that converges to the exact conformal field theory (CFT) in the continuum limit. The solution is based on reconciling Regge's simplicial geometry for the Einstein Hilbert action with an Affine map to quantum…
