Insulating phases of electrons on a zigzag strip in the orbital magnetic field [PDF]
, 2010 We consider electrons on a two-leg triangular ladder at half-filling and in an orbital magnetic field. In a two-band regime in the absence of the field, the electronic system remains conducting for weak interactions since there is no four-fermion Umklapp

Superlight small bipolarons [PDF]
, 2007 Recent angle-resolved photoemission spectroscopy (ARPES) has identified that a finite-range Fr\"ohlich electron-phonon interaction (EPI) with c-axis polarized optical phonons is important in cuprate superconductors, in agreement with an earlier proposal ...

Molecule by Molecule Characterization of a Polymer Molecular Mass Distribution via Mass Photometry
Angewandte Chemie, EarlyView.Mass photometry (MP) was utilized to achieve label‐free, molecule‐by‐molecule measurement of the full polymer molecular mass distribution (MMD) of a synthetic polymer without the need for sample fractionation. The ability to elucidate the full MMD in minutes, as opposed to having only specific moments of the MMD acquired in hours via chromatography ...

Quantum scars in spin- isotropic Heisenberg clusters
New Journal of Physics, 2023 We investigate the influence of the external fields on the statistics of energy levels and towers of eigenstates in spin- $1/2$ isotropic Heisenberg clusters, including chain, ladder, square and triangular lattices.

Super (a; d)-H-Antimagic Total Covering of Triangular Cycle Ladder Graph for Developing Ciphertext
CGANT JOURNAL OF MATHEMATICS AND APPLICATIONS, 2020 A (a; d)-H-antimagic total covering is a total labeling dari V (G) [ E(G) to integer number f1; 2; 3; :::; jV (G) [ E(G)jg with condition, every subgraph A inP P PG isomorphic with subgraph H A = v2V (A) (v) + e2E(A) (e) on arith-metic sequence. A graph containing the labeling called super (a; d)-H-antimagic total covering. Furthermore , f (v)gv2V = f1;

Entanglement Spectra of the quantum hard-square model: Holographic minimal models
, 2012 We study the entanglement properties of a quantum lattice-gas model for which we can find the exact ground state (of the Rokhsar-Kivelson type). The ground state can be expressed as a superposition of states, each of which is characterized by a particle ...

Wave-function positivization via automatic differentiation
Physical Review Research, 2020 We introduce a procedure to systematically search for a local unitary transformation that maps a wave function with a nontrivial sign structure into a positive-real form. The transformation is parametrized as a quantum circuit compiled into a set of one-
