Unified formalism for Thermal Quantum Field Theories: A geometric viewpoint [PDF]
Annals of Physics, 2018 In this paper we study a unified formalism for Thermal Quantum Field Theories, i.e., for the Matsubara approach, Thermo Field Dynamics and the Path Ordered Method. To do so, we employ a mechanism akin to the Hawking effect which explores a relationship between the concept of temperature and spacetimes endowed with event-horizons.

General Resource Theories in Quantum Mechanics and Beyond: Operational Characterization via Discrimination Tasks [PDF]
Physical Review X, 2019 We establish an operational characterization of general convex resource theories—describing the resource content of not only states but also measurements and channels, both within quantum mechanics and in general probabilistic theories (GPTs)—in the ...

General Quantum Resource Theories: Distillation, Formation and Consistent Resource Measures [PDF]
Quantum, 2020 Quantum resource theories (QRTs) provide a unified theoretical framework for understanding inherent quantum-mechanical properties that serve as resources in quantum information processing, but resources motivated by physics may possess structure whose ...

Topological holography, quantum criticality, and boundary states
SciPost Physics, 2023 Topological holography is a holographic principle that describes the generalized global symmetry of a local quantum system in terms of a topological order in one higher dimension. This framework separates the topological data from the local dynamics of a

Unified Theory of Local Quantum Many-Body Dynamics: Eigenoperator Thermalization Theorems [PDF]
Physical Review X, 2023 Explaining quantum many-body dynamics is a long-held goal of physics. A rigorous operator algebraic theory of dynamics in locally interacting systems in any dimension is provided here in terms of time-dependent equilibrium (Gibbs) ensembles.

Quantum magnetic monopole condensate
Communications Physics, 2021 Magnetic monopoles are predicted by grand unified theories but remain elusive as elementary particles. Here, extending electric-magnetic symmetry onto full quantum behavior, the authors demonstrate that magnetic monopoles emerge as excitations in ...
