Non-Invertible Symmetry Webs
Lakshya Bhardwaj, Lea E. Bottini, Sakura Schafer-Nameki +1
Non-invertible symmetries have by now seen numerous constructions in higher dimensional Quantum Field Theories (QFT). In this paper we provide an in depth study of gauging 0-form s…
Unifying Constructions of Non-Invertible Symmetries
Lakshya Bhardwaj, Sakura Schafer-Nameki, Apoorv Tiwari
In the past year several constructions of non-invertible symmetries in Quantum Field Theory in have appeared. In this paper we provide a unified perspective on these cons…
Interacting topological quantum chemistry of Mott atomic limits
Martina O. Soldini, Nikita Astrakhantsev, Mikel Iraola +6
Topological quantum chemistry (TQC) is a successful framework for identifying (noninteracting) topological materials. Based on the symmetry eigenvalues of Bloch eigenstates at maxi…
Topological Holography: Towards a Unification of Landau and Beyond-Landau Physics
Heidar Moradi, Seyed Faroogh Moosavian, Apoorv Tiwari
We outline a holographic framework that attempts to unify Landau and beyond-Landau paradigms of quantum phases and phase transitions. Leveraging a modern understanding of symmetrie…
Marginal quenches and drives in Tomonaga-Luttinger liquids
Shouvik Datta, Bastien Lapierre, Per Moosavi +1
We study Tomonaga-Luttinger liquids thrown out of equilibrium by marginal deformations in the form of interaction modulations. This is modeled by quenching or periodically driving…
Thermal and dissipative effects on the heating transition in a driven critical system
Kenny Choo, Bastien Lapierre, Clemens Kuhlenkamp +3
We study the dissipative dynamics of a periodically driven inhomogeneous critical lattice model in one dimension. The closed system dynamics starting from pure initial states is we…
Non-Invertible Higher-Categorical Symmetries
Lakshya Bhardwaj, Lea E. Bottini, Sakura Schafer-Nameki +1
We sketch a procedure to capture general non-invertible symmetries of a d-dimensional quantum field theory in the data of a higher-category, which captures the local properties of…
Anomalous gapped boundaries between surface topological orders in higher-order topological insulators and superconductors with inversion symmetry
Ming-Hao Li, Titus Neupert, S. A. Parameswaran +1
We show that the gapless boundary signatures - namely, chiral/helical hinge modes or localized zero modes - of three-dimensional higher-order topological insulators and superconduc…
Dephasing enhanced strong Majorana zero modes in 2D and 3D higher-order topological superconductors
Loredana M. Vasiloiu, Apoorv Tiwari, Jens H. Bardarson
The 1D Kitaev model in the topological phase, with open boundary conditions, hosts strong Majorana zero modes. These are fermion parity-odd operators that almost commute with the H…
Non-Hermitian topology in monitored quantum circuits
Christoph Fleckenstein, Alberto Zorzato, Daniel Varjas +3
We demonstrate that genuinely non-Hermitian topological phases and corresponding topological phase transitions can be naturally realized in monitored quantum circuits, exemplified…
