generalizations of three-dimensional stabilizer codes
Chanbeen Lee, Yaozong Hu, Gil Young Cho +1
In this work, we generalize several three-dimensional Z2 stabilizer models--including the X-cube model, the three-dimensional toric code, and Haah's code--to their ZN counterparts.…
Most two-dimensional bosonic topological orders forbid sign-problem-free quantum Monte Carlo: Nonpositive Gauss sum as an indicator
Donghae Seo, Minyoung You, Hee-Cheol Kim +1
Quantum Monte Carlo is a powerful tool for studying quantum many-body physics, yet its efficacy is often curtailed by the notorious sign problem. In this Letter, we introduce a nov…
Non-invertible duality and symmetry topological order of one-dimensional lattice models with spatially modulated symmetry
Donghae Seo, Gil Young Cho, Robert-Jan Slager
We investigate the interplay between self-duality and spatially modulated symmetry of generalized -state clock models, which include the transverse-field Ising model and ordinar…
Emergence of Meron Kekulé lattices in twisted Néel antiferromagnets
Kyoung-Min Kim, Se Kwon Kim
A Kekulé lattice is an exotic, distorted lattice structure exhibiting alternating bond lengths, distinguished from naturally formed atomic crystals. Despite its evident applicabili…
Stacking of charge-density waves in 2H-NbSe bilayers
Fabrizio Cossu, Dhani Nafday, Krisztian Palotás +4
We employ ab-initio electronic structure calculations to investigate the charge-density waves and periodic lattice distortions in bilayer 2H-NbSe. We demonstrate that the verti…

Cheong-Eung Ahn, Wonjun Lee, Kunihiro Yananose +2
Utilizing the realistic continuum description of twisted bilayer MoTe2 and many-body exact diagonalization calculation, we establish that the second moiré band of twisted bilayer M…
Disordered non-Fermi liquid fixed point for two-dimensional metals at Ising-nematic quantum critical points
Kyoung-Min Kim, Ki-Seok Kim
Understanding the influence of quenched random potential is crucial for comprehending the exotic electronic transport of non-Fermi liquid metals near metallic quantum critical poin…
Modular extension of topological orders from congruence representations
Donghae Seo, Minyoung You, Gil Young Cho +1
We present an efficient method to compute the modular extension of both fermionic topological orders and -symmetric bosonic topological orders in two spatial dimensio…

Md. Nur Hasan, Ritadip Bharati, Johan Hellsvik +10
The V-based kagome systems AV3Sb5 (A = Cs, Rb and K) are unique by virtue of the intricate interplay of non-trivial electronic structure, topology and intriguing fermiology, render…
Induced quantum magnetism in CEF singlet ground state models: Thermodynamics and excitations
Peter Thalmeier, Alireza Akbari
We present a comparative investigation of singlet ground state induced magnetism for singlet, doublet and triplet excited CEF states of non-Kramers f-electrons relevant primarily f…
Emergent Quantum Phenomena of Noncentrosymmetric Charge-Density Wave in 1T-Transition Metal Dichalcogenides
Cheong-Eung Ahn, Kyung-Hwan Jin, Young-Jae Choi +5
1T-transition metal dichalcogenides (TMD) have been an exciting platform for exploring the intertwinement of charge density waves and strong correlation phenomena. While the David…
Beyond quantum chaos in emergent dual holography

Yuji Hirono, Minyoung You, Stephen Angus +1
Fractonic phases are new phases of matter that host excitations with restricted mobility. We show that a certain class of gapless fractonic phases are realized as a result of spont…
Controllable Floquet edge modes in a multi-frequency driving system
