An argument by Banks, Susskind and Peskin (BSP), according to which violation of unitarity would violate either locality or energy-momentum conservation, is widely believed to be a strong argument against non-unitarity of Hawking radiation. We find that the whole BSP argument rests on the crucial assumption that the Hamiltonian is not highly degenerate, and point out that this assumption is not satisfied for systems with many degrees of freedom. Using Lindblad equation, we show that high… 
Black hole information paradox without Hawking radiation
By entangling soft massless particles one can create an arbitrarily large amount of entanglement entropy that carries an arbitrarily small amount of energy. Dropping this entropy into the black hole
AdS/CFT without holography: A hidden dimension on the CFT side and implications for black-hole entropy
We propose a new non-holographic formulation of AdS/CFT correspondence, according to which quantum gravity on AdS and its dual non-gravitational field theory both live in the same number D of
Unitary-Only Quantum Theory Cannot Consistently Describe the Use of Itself: On the Frauchiger–Renner Paradox
The Frauchiger–Renner Paradox is an extension of paradoxes based on the “Problem of Measurement,” such as Schrödinger’s Cat and Wigner’s Friend. All these paradoxes stem from assuming that quantum
No Purification Ontology, No Quantum Paradoxes
It is almost universally believed that in quantum theory the two following statements hold: (1) all transformations are achieved by a unitary interaction followed by a von-Neumann measurement; (2)
Return on Investment in Model‐Based Systems Engineering Software Tools
TLDR
The research finds that considerable organization returns are realized with investments in software tools, most significantly the reduction in engineering labor needed to perform engineering tasks.

TLDR
KDT improves MRP and quality of life in patients with abdominal symptoms; moreover, it is considered to be a safe and effective drug for elderly patients with FI.

Does black-hole evaporation imply that physics is non-unitary, and if so, what must the laws of physics look like? An Essay.
Stephen Hawking's discovery of black hole evaporation has the remarkable consequence that information is destroyed by a black hole, which can only be accommodated by modifying the laws of quantum

TLDR
It is argued (via consideration of other, non-Markovian models) that conservation of energy and momentum for all states is not fundamentally incompatible with causality in dynamical models in which pure states evolve to mixed states.
If time is a local observable, then Hawking radiation is unitary
In the usual formulation of quantum theory, time is a global classical evolution parameter, not a local quantum observable. On the other hand, both canonical quantum gravity (which lacks fundamental
Non-Unitary Holography
We propose gauge theory/gravity duality involving conformal theories based on U(N+k|k) gauge groups. We show that to all orders in 1/N these non-unitary theories based on supergroups are
Fundamental destruction of information and conservation laws
TLDR
It is proved that theories with information destruction can be made time-symmetric, thus impossing no arrow of time, and derived a generalisation of Noether's theorem for general theories.

Generalizations of normal ordering and applications to quantization in classical backgrounds
A nonlocal method of extracting the positive (or the negative) frequency part of a field, based on knowledge of a 2-point function, leads to certain natural generalizations of the normal ordering of
Squeezed quantum states of relic gravitons and primordial density fluctuations.
TLDR
It is shown that relic gravitons (and other primordial perturbations), created from zero-point quantum fluctuations in the course of cosmological evolution, should now be in strongly squeezed states.
