Quantum Brownian Representation for the Quantum Field Modes by Daniel Arteaga

“…When analyzing the particle-like excitations in quantum field theory it is natural to regard the field mode corresponding to the particle momentum as an open quantum system, together with the opposite momentum mode. …”

Isolated zeros destroy Fermi surface in holographic models with a lattice by Floris Balm, Alexander Krikun, Aurelio Romero-Bermúdez, Koenraad Schalm, Jan Zaanen

“…Abstract We study the fermionic spectral density in a strongly correlated quantum system described by a gravity dual. In the presence of periodically modulated chemical potential, which models the effect of the ionic lattice, we explore the shapes of the corresponding Fermi surfaces, defined by the location of peaks in the spectral density at the Fermi level. …”

Automated graph-based detection of quantum control schemes: Application to molecular laser cooling by Anna Dawid, Niccoló Bigagli, Daniel W. Savin, Sebastian Will

“…A central insight of this work is that the reinterpretation of quantum states and transitions between them as a graph can dramatically enhance the ability to identify new quantum control schemes for complex quantum systems. As such, this approach will also apply to complex atoms and, in fact, any complex many-body quantum system with a discrete spectrum of internal states.…”

Decoherence-enabled unconditional strongly sub-Poissonian squeezing by Qing Xu, Ke Zhang, Xiaobo Shen, Haijun Yu, Jiabing Zhu

“…This excludes the use of the paradigm that the good insulation of a quantum system from its surrounding environment is highly desirable to explore its quantum property and fuel the growth of quantum information science. …”

Integrability of open boundary driven quantum circuits by Chiara Paletta, Tomaž Prosen

“…Specifically, for a particular choice of free parameters, the solutions correspond to an open quantum system dynamics with the source terms representing injecting or removing particles from the boundary of the spin chain.…”

Remote cooling of spin-ensembles through a spin-mechanical hybrid interface by Yang Wang, Durga Bhaktavatsala Rao Dasari, Jörg Wrachtrup

“…Abstract We present a protocol for the ground-state cooling of a tripartite hybrid quantum system, in which a macroscopic oscillator acts as a mediator between a single-probe spin and a remote spin ensemble. …”

Geometrical Applications of Split Octonions by Merab Gogberashvili, Otari Sakhelashvili

“…It is shown how the G2 algebra’s chirality yields an intrinsic left-right asymmetry of a certain 3-vector (spin), as well as a parity violating effect on light emitted by a moving quantum system. Elementary particles are connected with the special elements of the algebra which nullify octonionic intervals. …”

Entanglement asymmetry and symmetry defects in boundary conformal field theory by Yuya Kusuki, Sara Murciano, Hirosi Ooguri, Sridip Pal

“…Abstract A state in a quantum system with a given global symmetry, G, can be sensitive to the presence of boundaries, which may either preserve or break this symmetry. …”

The Group-Algebraic Formalism of Quantum Probability and Its Applications in Quantum Statistical Mechanics by Yan Gu, Jiao Wang

“…As dynamical variables of a quantum system must respect certain commutation relations, we take the group generated by a Lie algebra constructed with these commutation relations as the bridge, so that the classical characteristic function defined in a Euclidean space is transformed to a normalized, non-negative definite function defined in this group. …”

Quantum features for a system of two qutrits in the presence of power-law potential field by Bahaaudin M. Raffah, K. Berrada, E.M. Khalil, S. Abdel-Khalek

“…We analyze the dynamical characteristics of this quantum system, taking into account the influences of both the T-Q initial state and the field parameters. …”

Nonreciprocal Synchronization of Active Quantum Spins by Tobias Nadolny, Christoph Bruder, Matteo Brunelli

“…Remarkably, continuous monitoring of the output field of the waveguides induces a quantum traveling-wave state: a time-crystalline state of a finite-size quantum system, in which parity-time symmetry is spontaneously broken. …”

Genetic Vectors as a Tool in Association Studies: Definitions and Application for Study of Rheumatoid Arthritis by Igor Sandalov, Leonid Padyukov

“…To identify putative relations between different genetic factors in the human genome in the development of common complex disease, we mapped the genetic data to an ensemble of spin chains and analysed the data as a quantum system. Each SNP is considered as a spin with three states corresponding to possible genotypes. …”

Relative entropy formulation of thermalization process in a Schwarzschild spacetime by Si-Wei Han, Zhichun Ouyang, Zhiyao Hu, Jun Feng

“…We derive the late-time dynamics of the detector in the context of open quantum system, and capture the path distinguishability and thermodynamic irreversibility of detector thermalization process by using quantum relative entropy (QRE). …”

Maximizing Free Energy Gain by Artemy Kolchinsky, Iman Marvian, Can Gokler, Zi-Wen Liu, Peter Shor, Oles Shtanko, Kevin Thompson, David Wolpert, Seth Lloyd

Limitations to Dynamical Error Suppression and Gate-Error Virtualization from Temporally Correlated Nonclassical Noise by Michiel Burgelman, Nattaphong Wonglakhon, Diego N. Bernal-García, Gerardo A. Paz-Silva, Lorenza Viola

“…By working within an open-quantum system Hamiltonian formulation, we revisit the validity of the notion of a constant gate error in the presence of noise that is both temporally correlated and nonclassical, and the impact of which is mitigated through perfect instantaneous dynamical decoupling subject to finite timing constraints. …”

Trellis Decoding for Qudit Stabilizer Codes and Its Application to Qubit Topological Codes by Eric Sabo, Arun B. Aloshious, Kenneth R. Brown

“…The resulting formalism is valid for any prime-dimensional quantum system. The modified decoder works for any stabilizer code <inline-formula><tex-math notation="LaTeX">$S$</tex-math></inline-formula> and separates into two parts: 1) a one-time offline computation that builds a compact graphical representation of the normalizer of the code, <inline-formula><tex-math notation="LaTeX">$\mathcal {S}^{\perp}$</tex-math></inline-formula> and 2) a quick, parallel, online query of the resulting vertices using the Viterbi algorithm. …”
