Peak-valley mechanism for Hilbert space fragmentation
Jianlong Fu, Hoi Chun Po
Ergodicity breaking in isolated systems has emerged as an important frontier in the study of quantum many-body physics. While generic Hamiltonians are expected to obey the eigensta…
Multipole phases in a type of spin ladders with local conserved quantities and generalizations
Jianlong Fu
We study spin ladder models with exact multipole phases, which are traditional spin phases formed by multipole moments. These phases feature non-trivial order with zero magnetizati…
Anomalous Landau levels and quantum oscillation in rotation-invariant insulators
Jianlong Fu, Chun Yu Weng, Hoi Chun Po
Landau levels in certain models are known to protrude into the zero-field energy gap. These are known as anomalous Landau levels (ALLs). We study whether ALLs can lead to Fermi-sur…
Exact weak bosonic zero modes in a spin/fermion chain
Jianlong Fu
We study an exactly solvable one-dimensional spin- model which can support weak zero modes in its ground state manifold. The spin chain has staggered XXZ-type and ZZ-t…
Majorana orthogonal transformation and Majorana zero modes in free fermionic systems
Jianlong Fu
We study free fermionic models that host Majorana zero modes using the Majorana orthogonal transformation, which is a type of transformation between different fermionic models unde…
Exact chiral spin liquid state in a Kitaev type spin model
Jianlong Fu
We study a frustrated two-dimensional lattice spin model with Kitaev type interaction. The lattice is obtained from the honeycomb lattice by replacing half of its sites with triang…
Properties and application of the SO(3) Majorana representation of spin: equivalence with the Jordan-Wigner transformation and exact gauge theories for spin models
Jianlong Fu
We explore the properties of the SO(3) Majorana representation of spin. Based on its non-local nature, it is shown that there is an equivalence between the SO(3) Majorana represent…
Majorana representations of spin and an alternative solution of the Kitaev honeycomb model
Jianlong Fu, Johannes Knolle, Natalia B. Perkins
Based on the Dirac spinor representation of the SO(4) group, we discuss the relationship between three types of representation of spin in terms of Majorana fermions, namely the Kit…
Fingerprints of quantum spin ice in Raman scattering
Jianlong Fu, Jeffrey G. Rau, Michel J. P. Gingras +1
We develop a theory of the dynamical response of a minimal model of quantum spin ice (QSI) by means of inelastic light scattering. In particular, we are interested in the Raman res…
Application of Mythen Detector In-situ XRD Study on The Thermal Expansion Behavior of Metal Indium
Rong Du, Zhongjun Chen, Quan Cai +3
A Mythen detector has been equipped at the beamline 4B9A of Beijing Synchrotron Radiation Facility, which can be used for in-situ real-time measurement of X-ray diffraction (XRD) f…
