CFT and Logarithmic Corrections to the Black Hole Entropy Product Formula by Parthapratim Pradhan

“…We examine the logarithmic corrections to the black hole (BH) entropy product formula of outer horizon and inner horizon by taking into account the effects of statistical quantum fluctuations around the thermal equilibrium and via conformal field theory (CFT). …”

Transparency, nonclassicality, and nonreciprocity in chiral waveguide quantum electrodynamics by Qingtian Miao, G. S. Agarwal

“…We also uncover a different type of critical coupling regime for qubits that enables complete suppression of forward-propagating amplitude transmission at specific driving powers, giving rise to enhanced nonreciprocal effects in both transmission and quantum fluctuations in amplitudes. Forward propagation amplifies the quantum fluctuations in amplitudes, while backward propagation significantly suppresses them. …”

Entanglement-Enhanced Atomic Gravimeter by Christophe Cassens, Bernd Meyer-Hoppe, Ernst Rasel, Carsten Klempt

“…However, their resolution is fundamentally restricted by quantum fluctuations. Improved resolutions with entangled or squeezed atoms were demonstrated in internal-state measurements for thermal and quantum-degenerate atoms and, recently, for momentum-state interferometers with laser-cooled atoms. …”

Quantum dimer models with Rydberg gadgets by Zhongda Zeng, Giuliano Giudici, Hannes Pichler

“…In these setups, we study the role of the quantum fluctuations induced by a coherent drive of the atoms and find signatures of U(1) and Z_{2} quantum spin liquid states in the respective ground states. …”

Emergent equilibrium and quantum criticality in a two-photon dissipative oscillator by V. Yu. Mylnikov, S. O. Potashin, G. S. Sokolovskii, N. S. Averkiev

“…Using the semiclassical Langevin equation and the truncated Wigner approximation, we construct a theory of nonperturbative quantum fluctuations and go beyond the semiclassical approximation. …”

Switching current distributions in superconducting nanostrips by Robert Vedin, Jack Lidmar

“…Due to thermal and/or quantum fluctuations the switching current will be random and follow a certain distribution depending on sweep rate, temperature, material properties, wire length, and width. …”

Connectomes as holographic states by Dmitry Melnikov

“…Generic states are linear combinations of connectomes, and the theory also has nonperturbative states which are global spacetime defects formed by a large number of quantum fluctuations. Topological presentation of quantum states and emergence of topology from entanglement may be useful for building a generalization to geometry, that is quantum gravity. …”

Soliton foam formation in the early Universe by A.A. Kirillov, B.S. Murygin, V.V. Nikulin

“…The realistic initial conditions are obtained through the simulation of multiple quantum fluctuations during the inflation epoch. The initial field distributions allow to form local soliton clusters in the early Universe without the need for the thermal production of a soliton network throughout the Universe. …”

Nonlocal Quantum Effects in Cosmology by Yurii V. Dumin

“…Since it is commonly believed that the observed large-scale structure of the universe is an imprint of quantum fluctuations existing at the very early stage of its evolution, it is reasonable to pose the question: do the effects of quantum nonlocality, which are well established now by the laboratory studies, manifest themselves also in the early universe? …”

Testing the lepton content of the proton at HERA and EIC by Leandro Da Rold, Anibal D. Medina, Subhojit Roy, Carlos E. M. Wagner

“…Abstract Although protons are baryons with an overall vanishing lepton number, they possess a non-trivial leptonic content arising from quantum fluctuations which can be described by lepton parton distribution functions (PDFs) of the proton. …”

Radiative corrections to the R and R 2 invariants from torsion fluctuations on maximally symmetric spaces by Riccardo Martini, Gregorio Paci, Dario Sauro

“…We also examine the conditions required to avoid ghost instabilities and ensure the validity of our assumption to neglect metric quantum fluctuations, demonstrating the compatibility between these two assumptions. …”

Quantum quench dynamics of geometrically frustrated Ising models by Ammar Ali, Hanjing Xu, William Bernoudy, Alberto Nocera, Andrew D. King, Arnab Banerjee

“…Abstract Geometric frustration in two-dimensional Ising models allows for a wealth of exotic universal behavior, both Ising and non-Ising, in the presence of quantum fluctuations. In particular, the triangular antiferromagnet and Villain model in a transverse field can be understood through distinct XY pseudospins, but have qualitatively similar phase diagrams including a quantum phase transition in the (2+1)-dimensional XY universality class. …”

Physics-Informed Deep Learning for Three Dimensional Black Holes by Emad Yaraie, Hossein Ghaffarnejad, Mohammad Farsam

“…Data has been collected by choosing minimally coupled massive scalar field with quantum fluctuations and we try to process two emergent and ground-truth metrics versus the holographic parameter which plays the role of depth of the neural network. …”
