Simulating fermionic fractional Chern insulators with infinite projected entangled-pair states
Hao Chen, Titus Neupert, Juraj Hasik
Infinite projected entangled-pair states (iPEPS) provide a powerful variational framework for two-dimensional quantum matter and have been widely used to capture bosonic topologica…
How quantum fluctuations freeze a classical liquid and then melt it into a topological one
Hao Chen, Dan Mao, Andrea Kouta Dagnino +5
Topologically ordered quantum liquids are highly sought-after quantum phases of matter, and recently, fractional Chern insulators (FCIs) joined the few experimental realizations of…
Exploiting the Hermitian symmetry in tensor network algorithms
Oscar van Alphen, Stijn V. Kleijweg, Juraj Hasik +1
Exploiting symmetries in tensor network algorithms plays a key role for reducing the computational and memory costs. Here we explain how to incorporate the Hermitian symmetry in do…
YASTN: Yet another symmetric tensor networks; A Python library for abelian symmetric tensor network calculations
Marek M. Rams, Gabriela Wójtowicz, Aritra Sinha +1
We present an open-source tensor network Python library for quantum many-body simulations. At its core is an abelian-symmetric tensor, implemented as a sparse block structure manag…
Simulating Spin Dynamics of Supersolid States in a Quantum Ising Magnet
Yi Xu, Juraj Hasik, Boris Ponsioen +1
Motivated by a recent experimental study on the quantum Ising magnet that presented spectroscopic evidence of zero-field supersolidity (Chen e…
Incommensurate order with translationally invariant projected entangled-pair states: Spiral states and quantum spin liquid on the anisotropic triangular lattice
Juraj Hasik, Philippe Corboz
Simulating strongly correlated systems with incommensurate order poses significant challenges for traditional finite-size-based approaches. Confining such a phase to a finite-size…
Phase diagram of the chiral SU(3) antiferromagnet on the kagome lattice
Yi Xu, Sylvain Capponi, Ji-Yao Chen +6
Motivated by the search for chiral spin liquids (CSL), we consider a simple model defined on the kagome lattice of interacting SU(3) spins (in the fundamental representation) inclu…
Improved summations of -point correlation functions of projected entangled-pair states
Boris Ponsioen, Juraj Hasik, Philippe Corboz
Numerical treatment of two dimensional strongly-correlated systems is both extremely challenging and of fundamental importance. Infinite projected entangled-pair states (PEPS), a c…
Quantum Melting of Spin-1 Dimer Solid Induced by Inter-chain Couplings
Yi Xu, Tianfu Fu, Juraj Hasik +1
Dimerized valence bond solids appear naturally in spin-1/2 systems on bipartite lattices, with the geometric frustrations playing a key role both in their stability and the eventua…
Chiral spin liquids on the kagome lattice with projected entangled simplex states
Sen Niu, Juraj Hasik, Ji-Yao Chen +1
The infinite projected entangled simplex state (iPESS), a type of tensor network (TN) state, has been used successfully for simulating and characterizing {\it non-chiral} spin liqu…
Static and dynamical signatures of Dzyaloshinskii-Moriya interactions in the Heisenberg model on the kagome lattice
Francesco Ferrari, Sen Niu, Juraj Hasik +3
Motivated by recent experiments on CsCuSnF and YCu(OH)Cl, we consider the Heisenberg model on the kagome lattice with nearest-neighbor su…
Symmetric projected entangled-pair states analysis of a phase transition in coupled spin-1/2 ladders

Doubts have been raised on the representation of chiral spin liquids exhibiting topological order in terms of projected entangled pair states (PEPSs). Here, starting from a simple…
The emergence of gapless quantum spin liquid from deconfined quantum critical point
Wen-Yuan Liu, Juraj Hasik, Shou-Shu Gong +3
A quantum spin liquid (QSL) is a novel phase of matter with long-range entanglement where localized spins are highly correlated with the vanishing of magnetic order. Such exotic qu…
