Dynamical properties of the random Heisenberg chain
Yu-Rong Shu, Maxime Dupont, Dao-Xin Yao +2
We use numerical techniques to study dynamical properties at finite temperature () of the Heisenberg spin chain with random exchange couplings, which realizes the random singlet…
Symmetry breaking and fermionic fractional Chern insulator in topologically trivial bands
Stefanos Kourtis
We describe a mechanism by which fermions in topologically trivial bands can form correlated states exhibiting a fractional quantum Hall (FQH) effect upon introduction of strong re…
Floquet Supersymmetry
Thomas Iadecola, Timothy H. Hsieh
We show that time-reflection symmetry in periodically driven (Floquet) quantum systems enables an inherently nonequilibrium phenomenon structurally similar to quantum-mechanical sy…
A model of chiral spin liquids with Abelian and non-Abelian topological phases
Jyong-Hao Chen, Christopher Mudry, Claudio Chamon +1
We present a two-dimensional lattice model for quantum spin-1/2 for which the low-energy limit is governed by four flavors of strongly interacting Majorana fermions. We study this…
Weyl-type topological phase transitions in fractional quantum Hall like systems
Stefanos Kourtis, Titus Neupert, Christopher Mudry +2
We develop a method to characterize topological phase transitions for strongly correlated Hamiltonians defined on two-dimensional lattices based on the many-body Berry curvature. O…
Nearly deconfined spinon excitations in the square-lattice spin-1/2 Heisenberg antiferromagnet
Hui Shao, Yan Qi Qin, Sylvain Capponi +3
We study the dynamic spin structure factor of the spin- square-lattice Heisenberg antiferromagnet and of the - model (with 4-spin interactions and Heisenberg exchang…
Signatures of fractionalization in spin liquids from interlayer thermal transport
Yochai Werman, Shubhayu Chatterjee, Siddhardh C. Morampudi +1
Quantum spin liquids (QSLs) are intriguing phases of matter possessing fractionalized excitations. Several quasi-two dimensional materials have been proposed as candidate QSLs, but…
Dynamics of the spin-1/2 Heisenberg chain initialized in a domain-wall state
Grégoire Misguich, Kirone Mallick, P. L. Krapivsky
We study the dynamics of an isotropic spin-1/2 Heisenberg chain starting in a domain-wall initial condition, where the spins are initially up on the left half-line and down on the…
Replica resummation of the Baker-Campbell-Hausdorff series
Szabolcs Vajna, Katja Klobas, Tomaz Prosen +1
We developed a novel perturbative expansion based on the replica trick for the Floquet Hamiltonian governing the dynamics of periodically kicked systems where the kick strength is…
Duality between the deconfined quantum-critical point and the bosonic topological transition
Yan Qi Qin, Yuan-Yao He, Yi-Zhuang You +5
Recently significant progress has been made in -dimensional conformal field theories without supersymmetry. In particular, it was realized that different Lagrangians may be…
Competing Bose-Glass physics with disorder-induced Bose-Einstein condensation in the doped antiferromagnet Ni(ClBr)-4SC(NH) at high magnetic fields
Maxime Dupont, Sylvain Capponi, Mladen Horvatić +1
We study the interplay between disorder and interactions for emergent bosonic degrees of freedom induced by an external magnetic field in the Br-doped spin-gapped antiferromagnetic…
Indicators of Conformal Field Theory: entanglement entropy and multiple-point correlators
Pranay Patil, Ying Tang, Emanuel Katz +1
The entanglement entropy (EE) of quantum systems is often used as a test of low-energy descriptions by conformal field theory (CFT). Here we point out that this is not a reliable i…
Dynamic scaling of the restoration of rotational symmetry in Heisenberg quantum antiferromagnets
Phillip Weinberg, Anders Sandvik
We apply imaginary-time evolution, , to study relaxation dynamics of gapless quantum antiferromagnets described by the spin-rotation invariant Heisenberg Hamiltonian…
Entanglement Complexity in Quantum Many-Body Dynamics, Thermalization and Localization
Zhi-Cheng Yang, Alioscia Hamma, Salvatore M. Giampaolo +2
Entanglement is usually quantified by von Neumann entropy, but its properties are much more complex than what can be expressed with a single number. We show that the three distinct…
Ground state degeneracy of non-Abelian topological phases from coupled wires
Thomas Iadecola, Titus Neupert, Claudio Chamon +1
We construct a family of two-dimensional non-Abelian topological phases from coupled wires using a non-Abelian bosonization approach. We then demonstrate how to determine the natur…
Critical level crossings and gapless spin liquid in the square-lattice spin- - Heisenberg antiferromagnet
Ling Wang, Anders W. Sandvik
We use the DMRG method to calculate several energy eigenvalues of the frustrated square-lattice - Heisenberg model on cylinders with . We…
