Engineering logical gates with irrep surface codes
Yabo Li, Zijian Song, Vieri Mattei +3
Fault-tolerant quantum computation can incur a substantial resource cost when a desired logical operation must be constructed from a restricted set of logical primitives. To make s…
Crystalline topological invariants in quantum many-body systems
Naren Manjunath, Maissam Barkeshli
Crystalline symmetries give rise to topological invariants that can distinguish quantum phases of matter. Understanding these in strongly interacting systems is an ongoing research…
Universal quantum computation with group surface codes
Naren Manjunath, Vieri Mattei, Apoorv Tiwari +1
We introduce group surface codes, which are a natural generalization of the surface code, and equivalent to quantum double models of finite groups with specific boun…
Quantum criticality at strong randomness: a lesson from anomaly
Yasamin Panahi, Subhayan Sahu, Naren Manjunath +1
Quantum criticality in the presence of strong quenched randomness remains a challenging topic in modern condensed matter theory. We show that the topology and anomaly associated wi…
In search of diabolical critical points
Naren Manjunath, Dominic V. Else
A phase transition is an example of a ``topological defect'' in the space of parameters of a quantum or classical many-body systems. In this paper, we consider phase diagram topolo…
Detection of 2D SPT phases under decoherence
Naren Manjunath, Alex Turzillo, Chong Wang
We propose a bulk order parameter for extracting symmetry-protected topological (SPT) invariants of quantum many-body mixed states on a two dimensional lattice using partial symmet…
Symmetry constrained field theories for chiral spin liquid to spin crystal transitions
Anjishnu Bose, Andrew Hardy, Naren Manjunath +2
We consider the spin rotationally invariant Kalmeyer-Laughlin chiral spin liquid (CSL) in systems with broken time-reversal symmetry and explore symmetry constraints on possible co…
Detection of 2D SPT Order with Partial Symmetries
Alex Turzillo, Naren Manjunath, Jose Garre-Rubio
A method of using partial symmetries to distinguish two dimensional symmetry protected topological (SPT) phases of on-site, unitary symmetries is proposed. This novel order paramet…
Anomalous continuous symmetries and quantum topology of Goldstone modes
Naren Manjunath, Dominic V. Else
We consider systems in which a continuous symmetry , which may be anomalous, is spontaneously broken to an anomaly-free subgroup such that the effective action for the Golds…
