Lattice Laughlin states of bosons and fermions at filling fractions 1/q

New Journal of Physics, 2014
We introduce a two-parameter family of strongly-correlated wave functions for bosons and fermions in lattices. One parameter, q , is connected to the filling fraction.

Algebraic Geometry of Matrix Product States [PDF]

, 2014
. We quantify the representational power of matrix product states (MPS) for entangled qubit systems by giving polynomial expressions in a pure quantum state’s am-plitudes which hold if and only if the state is a translation invariant matrix product state

A non-integrable quench from AdS/dCFT

Physics Letters B, 2019
We study the matrix product state which appears as the boundary state of the AdS/dCFT set-up where a probe D7 brane wraps two two-spheres stabilized by fluxes.

Imaginary-Time Matrix Product State Impurity Solver for Dynamical Mean-Field Theory

Physical Review X, 2015
We present a new impurity solver for dynamical mean-field theory based on imaginary-time evolution of matrix product states. This converges the self-consistency loop on the imaginary-frequency axis and obtains real-frequency information in a final real ...

Chebyshev pseudosite matrix product state approach for the spectral functions of electron-phonon coupling systems

Physical Review Research, 2023
The electron-phonon (e-ph) coupling system often has a large number of phonon degrees of freedom, whose spectral functions are numerically difficult to compute using matrix product state (MPS) formalisms.

Matrix product state renormalization

, 2016
The truncation or compression of the spectrum of Schmidt values is inherent to the matrix product state (MPS) approximation of one-dimensional quantum ground states.

Matrix-Product-State Algorithm for Finite Fractional Quantum Hall Systems

, 2015
Exact diagonalization is a powerful tool to study fractional quantum Hall (FQH) systems. However, its capability is limited by the exponentially increasing computational cost.

Stochastic matrix product states [PDF]

, 2010
The concept of stochastic matrix product states is introduced and a natural form for the states is derived. This allows us to define the analogue of Schmidt coefficients for steady states of nonequilibrium stochastic processes.

Effect of DFPP on Ferroptosis in Peripheral Blood CD14+ Monocytes of Hyperlipidemic Patients Involving the ACSL4/LPCAT3/ALOX5 Pathway

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Hyperlipidemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD). Although statins are the cornerstone of lipid‐lowering therapy, their use may be limited in some patients by adverse effects. This study evaluated the possible impact of non‐drug treatment using double‐filtration plasmapheresis (DFPP) on CD14+

Matrix product state on a quantum computer

New Journal of Physics
Solving quantum many-body systems is one of the most significant regimes where quantum computing applies. Currently, as a hardware-friendly computational paradigms, variational algorithms are often used for finding the ground energy of quantum many-body ...
