Second quantization of many-body dispersion interactions for chemical and biological systems [PDF]
Nature Communications, 2023 The many-body dispersion (MBD) framework is a successful approach for modeling the long-range electronic correlation energy and optical response of systems with thousands of atoms.

From Quantum Time to Manifestly Covariant QFT: On the Need for a Quantum-Action-Based Quantization [PDF]
EntropyIn quantum time (QT) schemes, time is promoted to a degree of freedom, allowing Lorentz covariance to be made explicit for single particles. We ask whether this can be lifted to QFT so that Lorentz covariance becomes manifest at the Hilbert-space level ...

Boson–Fermion Algebraic Mapping in Second Quantization [PDF]
EntropyWe present an algebraic method to derive the structure at the basis of the mapping of bosonic algebras of creation and annihilation operators into fermionic algebras, and vice versa, introducing a suitable identification between bosonic and fermionic ...

Majorana Mass Term of Majorana Spinors
Physical Sciences Forum, 2023 We have proven that, under the standard charge conjugation approach, the Majorana mass term in QFT must vanish. We have derived formulas for the Majorana spinor field operator without any assumptions about the second quantization procedure. The fact that

Antimatter Gravity: Second Quantization and Lagrangian Formalism
Physics, 2020 The application of the CPT (charge-conjugation, parity, and time reversal) theorem to an apple falling on Earth leads to the description of an anti-apple falling on anti–Earth (not on Earth).

A fourth‐order incremental ADC in three‐step
The Journal of Engineering, 2021 This letter presents a second‐order incremental ADC (IADC) operated in three steps, which extends the performance of a second‐order IADC close to that of a fourth‐order IADC with only two amplifiers.

SECOND QUANTIZED KOLMOGOROV COMPLEXITY [PDF]
International Journal of Quantum Information, 2008 The Kolmogorov complexity of a string is the length of its shortest description. We define a second quantized Kolmogorov complexity where the length of a description is defined to be the average length of its superposition. We discuss this complexity's basic properties.

Quantum computation for periodic solids in second quantization
Physical Review Research, 2023 In this work, we present a quantum algorithm for ground-state energy calculations of periodic solids on error-corrected quantum computers. The algorithm is based on the sparse qubitization approach in second quantization and developed for Bloch and ...

Vojnotehnički Glasnik, 2023 Introduction/purpose: The quantization of the electromagnetic field gives rise to quantum fluctuations which in turn produce a force on macroscopic boundaries. This phenomenon is called the Casimir effect.

Light-cone quantization of scalar field on time-dependent backgrounds
European Physical Journal C: Particles and Fields, 2022 We discuss what is light-cone quantization on a curved spacetime also without a null Killing vector. Then we consider as an example the light-cone quantization of a scalar field on a background with a Killing vector and the connection with the second ...
