Quantized pumping of boundary Hilbert space in chiral Floquet phases
Ryota Nakai, Taozhi Guo, Shinsei Ryu
Chiral Floquet phases support quantized chiral flow along their boundaries even when the bulk is fully localized. In this Letter, we establish a complementary phenomenon, which we…
Canonical Partition Function on a Quantum Computer through Trotter Interpolation
Taozhi Guo, Gumaro Rendon, Rutuja Kshirsagar
In this work, we present a Gibbs state observable estimation algorithm based on Trotter interpolation, which reaches a state-of-the-art quantum computational cost of $ \tilde{O}(β\…
Discrete time crystals detected by time-translation twist
Ryota Nakai, Taozhi Guo, Shinsei Ryu
We introduce a boundary condition twisted by time translation as a novel probe to characterize dynamical phases in periodically driven (Floquet) quantum systems. Inspired by twiste…
Twisted-Boundary-Condition Formalism for Thermal Transport and an Application to the One-Dimensional XY Spin Chain
Ryota Nakai, Taozhi Guo, Shinsei Ryu
We introduce and formulate the boundary condition twisted by the energy (time translation) in one-dimensional quantum many-body systems. The stiffness against this boundary conditi…
Spatial deformation of many-body quantum chaotic systems and quantum information scrambling
Kanato Goto, Taozhi Guo, Tomoki Nosaka +3
We study the effect of spatial inhomogeneity on quantum information scrambling, a process of spreading and locally hiding quantum information in quantum many-body systems. As a par…
Non-Hermitian boost deformation
Taozhi Guo, Kohei Kawabata, Ryota Nakai +1
The Hatano-Nelson model is one of the most prototypical non-Hermitian models that exhibit the intrinsic non-Hermitian topological phases and the concomitant skin effect. These phen…
Epitaxial growth, magnetoresistance, and electronic band structure of GdSb magnetic semimetal films
Hadass S. Inbar, Dai Q. Ho, Shouvik Chatterjee +12
Motivated by observations of extreme magnetoresistance (XMR) in bulk crystals of rare-earth monopnictide (RE-V) compounds and emerging applications in novel spintronic and plasmoni…
Energy-twisted boundary condition and response in one-dimensional quantum many-body systems
Ryota Nakai, Taozhi Guo, Shinsei Ryu
Thermal transport in condensed matter systems is traditionally formulated as a response to a background gravitational field. In this work, we seek a twisted-boundary-condition form…
Identifying the fingerprints of topological states by tuning magnetoresistance in a semimetal: the case of topological half-Heusler Pt1-xAuxLuSb
Shouvik Chatterjee, Felipe Crasto de Lima, John A. Logan +18
Topological materials often exhibit remarkably linear, non-saturating magnetoresistance (LMR), which is both of scientific and technological importance. However, the role of topolo…
Controlling magnetoresistance by tuning semimetallicity through dimensional confinement and heteroepitaxy
Shouvik Chatterjee, Shoaib Khalid, Hadass S. Inbar +7
Controlling the electronic properties via bandstructure engineering is at the heart of modern semiconductor devices. Here, we extend this concept to semimetals where, utilizing LuS…
